Product Details

Dayton Audio RSS315HF-4 12" Reference HF Subwoofer 4 Ohm

As with the rest of the Dayton Audio Reference Series speakers, the main focus of these subwoofers is ultra-low-distortion. Second, third, and intermodulation distortion are kept extremely low by utilizing three short-circuit paths within the motor structure. A durable aramid fiber spider and extensive venting throughout provide quiet and uniform excursion for the Reference Series RSS315HF-4 12" subwoofer speaker. The black anodized cone, rubber surround, and custom basket give this driver and the rest of the Reference Series a unique, high-end look. Choose the high fidelity version for home systems when you are looking for clean, low bass and are not restricted by cabinet size.

Rated 5 out of 5 by from Nothing goes wrong with Dayton Audio!I bought two of these subs. I built a 3.3 cu. ft. ported box tuned to 30hz. These subs move a lot of air! I just love that deep bass!These subs can hit really hard and get really loud if you put them in the right enclosure. This way, you will get the most output from the sub and the sub will perform at its best!There's no distortion, very well built sub, very nice looking, sounds very good!This sub is the perfect match for you! Buy it today and this sub will not disappoint you!

Rated 5 out of 5 by from Great Sub - very satisfiedI had a 30 year old MK sub with a plate amp that quit on me and I started my search for a replacement. I found this site and after some research settled on a Dayton Audio RSS315HF-4 12" sub and a Dayton Audio SA230 amp. I wanted a component amp so I could easily make adjustments without crawling on the floor for the sub.I used the old enclosure (modified by me to keep a sealed box after I removed the old plate amp). My box is 1.97 cu ft and Parts Express suggested this speaker for my configuration.I have a large (28 x 24) room with high ceilings and a basic Onkyo 5.1 receiver with an older set of Mission speakers (3 way w/ 8" woofers). I selected the amp because it had both high and sub level inputs with a crossover. For normal music, I use the high level inputs (crossing at 100hz) take the bass off the Mission speakers. For 5.1 surround I use sub input from the Onkyo.On music, this combination rocks and is overpowering. This set-up has the potential to put the local high school student's boom box inspired car stereo to shame. Once dialed back to about 1/2 throttle it sounds excellent.On movies (Lord of the Rings blue ray) on the low level sub inputs it sounds very good but not nearly as overpowering. I wish it had a little more punch, but that could also be a reflection of my 10 yr old Onkyo receiver not delivering the goods to the sub.I have no complaints about this system and am very satisfied. I wish the larger Dayton amp had high level inputs because that would have been a serious contender for my set up.

Rated 5 out of 5 by from Just give it some time.Ok people. When this sub first meets power you will be disappointed. (dont stop reading, this is actually a positive review) you'll cus a bit and ask yourself why the heck you spent so much money on a subwoofer that seems to be very unresponsive and seems very quiet. Well.. just give it some time. Every subwoofer.. no, every speaker ever created has a break in period, which is very important. The way you treat your new equipment decides how that same equipment will play when its no longer brand new. Feed this sub maybe half the power it should handle for a few days and it will start to sound a lot better. After you baby it for a while give it some more juice for semi short amounts of time. Thoroughly break this thing in and it comes alive. Very responsive and powerfull through the whole range of what it should play. I will soon be buying another. Great sub

Rated 2 out of 5 by from DissapointedI recently purchased this subwoofer to replace my old SD315A-88. The old sub was mounted in a 3 cubic feet box with a SPA250 watt plate amp. As I played a few songs i noticed that the speaker did much more flexing and put out less sound. The old sub would reverberate beautifully and was a third of the price. I played songs that my old sub preformed well on, and my new sub slaughtered. I know that my plate amp doesn't exactly have the right power specifications to handle the sub, but with 100 watts running into it i expected much more. It was truly a disappointment with all the hype the reviews gave it.

Rated 5 out of 5 by from RSS315HF-4 12" Impressive SubwooferI have gone through many subwoofers over the years but usually it was automotive. I guess it was hard for me to get away from my roots as I am using auto subs for my HT. I am running an original JL Audio W6 15" on an OAudio 500 plate amp and thought it sounded great. I also replaced an Onkyo sub with an Audiobahn 10" just to see how it would perform. It sounds decent but obvious it does not belong.I read the many reviews on this speaker and figured the price was right. Being I paid over $300 for the JL 11 years ago. The first thing I noticed when it came out of the box was how sturdy this speaker felt. The magnet is HUGE and the basket extemely rigid. I felt as if I should attach a chain to it and use it as a weapon. Just kidding. Not really. At this time I have it placed in Atrend box you would usually find in my trunk. The box only has around 1.3 cu ft of room which in my opinion is really holding this sub back. The atrend box is well built so I think I will just add about 6 inches to the top of it and add a flare port.Even in its current cramped condition the sub pounds out the lows with precise clarity. I watched Transformers the day I hooked it up and was truly amazed. The JL still out performs this sub but just barely. I am positive when I give this bad boy some more room to breathe that it will easily put the JL to shame.Great Subwoofer at a great price. Just make sure you compliment it with a well designed box.

Rated 5 out of 5 by from Excellent subwoofersI made two sealed subwoofer cabinets for my home theatre out of MDF board. Each is 3 cubic feet with heavy internal bracing. The result is a smooth sound that doesn't just boom like my old '700' watt name brand subwoofer. They sound great with both movies and music. I used a Crown XLS series amplifier to push the subs and the team is a perfect match.

Rated 5 out of 5 by from Dayton HF 12" ReviewAnother excellent value from the folks @ PE & Dayton Audio!Very good mobile audio performance between 30-90 hz from a pair of these subs in 2.5 cu.ft. (Qtc = .9 / F3 ~ 40hz) powered by Kenwood eXcelon XR-1S (700 watts @ 2 ohms).

Rated 5 out of 5 by from Great DriverI probably have at least 30 of these in various customers theaters. What I like best about them is their ability to play both music and the big booms in movies equally well.And best of all, I have never had one fail.

Rated 5 out of 5 by from Paired with Bash300I built a 2.6ft^3 box and paired it with a Bash300 amp. This thing literally shakes my eyes in my 14x10x8 living room. Blows away my Onkyo HTIB sub by miles! The clarity of the low end just keeps going.

Rated 5 out of 5 by from Dayton Audio RSS315HF-4 12" Reference HF Subwoofer 4 OhmI used two of these in twin sealed subwoofers modeled after the RS1200 project found in the Parts Express project showcase. I prefer to build my own enclosures, so I built one a smidgeon larger @ 1.7 cubic feet net volume with a heathier brace. I used two of the Dayton Audio SPA500 500W subwoofer plate amplifiers as per the project. I reviewed the plate amplifiers as well is you wish to check it out. I could not be happier with these drivers. Low, smooth and deep. They respond well to the plate amps. Initally, I set the plate amps' parametric equalizer at a +4db boost on the 20-40 hz freqencies, but later turned it down to about 1.5 decibel boost to compensate for the shortcomings in the extreme low end frequencies of sealed enclosures. Very pleased. Would quickly replace if they break outside of warranty

Rated 5 out of 5 by from Musical subI love this subwoofer. I use two of them mostly for music to augment my mains in a 20 x 18 ft room that opens to other areas of the house. They are each in a sealed box ~ 2.5 cu ft driven by old cerwin vega plate amp (only 100watts). Efficient drivers and they integrate very well with the mains. They can rattle the picture frames on my walls when called for but that's not for a music lover like me.I started with one sub. It was quite sufficient for my listening room but I went overboard and added the second sub. Not so much to add extra volume to bass but to actually smooth/average out room modes. The subs actually bring out the tonal richness of the musical content quite well. And ofcourse the folks at PE are just great to do business with! Highly recommended subwoofer for music applications.

Rated 5 out of 5 by from Dayton Audio RSS315HF-4 12"I had a Paradigm 2200 subwoofer and the speaker went out. So I purchased this 12", knowing that I would have to modify the opening a little to get it to drop in. After I got it installed and turned it on. It worked just fine, I can't say that it sounded better, but it definetly sounded as good or even a little more output. The speaker itself is nicer build quality and heavier magnet then the original paradigm. Definetly worth the money, instead of building or buying new again!

Rated 5 out of 5 by from Replacement for old subwooferI have an old Velodyne 1512 powered subwoofer. Never have been completely satisfied with this sub, mainly because I believed that it never had any guts.Over the years the surround gave way and I decided I would just replace the driver with the Dayton RSS315HF. I would say after a month of listening that I should have replaced the old speaker about 10 years ago. I had to turn the amp down on the sub so I wouldn't break anything. My experience has shown this to be an excellent speaker. I would purchase again without hesitation. Extremely strong, powerful, and accurate in my estimation. I don't get the sense that it is muddy like my old speaker. Excellent buy! One other note. I had to make a slight modification to the old sub box for the outside diameter of the speaker, but I knew this when I purchased the speaker. It was worth the modification, you can't see my router cut with the grill on anyway. The sound and power justified any mods to the box.

Rated 5 out of 5 by from SonosubBuilt 18"x48" sonosub with 6" port tuned to 19Hz powered by PE 240W plate amp. Sounds fantastic in my HT. Total build price was just over $300 and pretty simple if you have a plunge router. Can easily make you're own circle jig. This was so simple and cheap, I might have to make a second one for total overkill.

Rated 5 out of 5 by from Great sound even at high volumesI bought two and put them in a pair of 35 year old sealed boxes each of which originally had a set of 4 Jantzen electrostatics and a 12" driver. I had removed the ES drivers and covered over the openings. The new 12" drivers fit in perfectly, even the mounting holes. The sound is deep and clean, with no doubling over at high volumes. They seem to improve as time goes buy. I found them best positioned in a corner, one on top of the other, and each facing down an opposite wall. I run the subwoofer output from my Yamaha receiver to an old Onkyo receiver with 2 x 100 W, which is now the subwoofer amp. The new drivers handle everything below about 100 Hz, which is the best crossover frequency for subs because it eliminates the Doppler distortion in the lower midrange. Because of the huge magnet and stiff suspension I believe they can be mounted in almost anything. The enclosure should has only a small effect on performance.

Rated 5 out of 5 by from Awesome subwoofer driverBuilt a 3.3 cu.ft. box for it, tuned to it's free air resonance. Measures flat in my largish room to below 20Hz. Very musical bass, great LFE. I was leaning toward getting the Titanic, but I'm glad I chose this one instead. It's really well built, very stout.Literally shakes the room like an earthquake, and it's very efficient. At the moment I'm only running 100W into it. I can't imagine what it will do if run at it's rated power, but I intend to find out!

Rated 5 out of 5 by from Very Nice DriverInstalled this driver in a 3.2 cuft. cabinet (WinISD modeled for best sealed Q) but added a floor-firing, slot-loaded 12" Dayton passive radiator tuned to be -3db at about 18 Hz. (WinISd models that to achieve similar response from a ported design would require a 4" x 11" port in a 5.8 cuft cabinet - 80% larger!). Completely satisfied with outcome. No extra weight added to passive to keep it light and fast, 1 1/4" all around, all sides braced, with Dayton 240 watt amp installed. Weighs 118 lbs and lined with 1" Sonic Barrier - very solid, deep, powerful, clean sound. Very impressed. One audiophile friend says 'best bass he has ever heard!'. Highly recommend this driver.

Rated 5 out of 5 by from Good SubVery solidly built sub. Nice clean deep bass if you make the right enclosure. I just wish it had a bit more power handling. Don't care much for the terminals either but they do the job.I would definitely recomend this sub to anyone who wants a sub that hits low, clean and looks good doing it.

Rated 5 out of 5 by from Just What I Was Looking ForI wanted a sub that plays well with music and Home Theater. This Dayton RSS315HF-4 nails it. Very deep, very powerful, very clean bass for both applications.My Project Specs:I built an enclosure 19" H, 15" W, 18" D (external dimensions). Internal volume minus the driver, port and bracing (no plate amp) = 1.94 cu. ft. The bracing is 2 1/2" x 3/4" solid oak running down the middle of the length of each of the 4 side walls of the cabinet all the way from the front to the back (16.5").Used the 4" Flared Port Tube Kit (268-352). Cut the port to a total length of 10 inches. It exits the back of the enclosure directly behind the subwoofer.The sides and back of the enclosure are lined with 1 1/2" Acoustic Foam (260-516). The subwoofer is mounted using the #10-32 Speaker Mounting Kit (260-776). I used Hurricane Nuts (081-1082) instead of the supplied T-Nuts. I bought a 4" Test Plug (Oatey 33403) at Lowe's to plug the port to see what it would sound like sealed. I much prefer the ported enclosure -- it plays with much more power. But if you prefer a sealed enclosure the Test Plug makes this a very versatile enclosure.I built two of these enclosures and placed them next to the front left and right speakers. STUNNING deep, powerful and clean bass! Everyone who hears them is blown away by the shear power of these things.They are powered by two plate amps that I placed in the stereo cabinet next to the recliner. That way I can adjust them with ease.

Rated 5 out of 5 by from Outstanding SubwooferI was very impressed with the build quality of this subwoofer (and I don't mean "for the price"); this unit is rock-solid, with a heavy-gauge aluminum cone, tough surround, and a healthy ~10 lb. magnet. Add a solid cast frame and gold-plated solderless connects and you've got a very well-constructed unit.As for the sound, I would have to agree with other reviews that this sub is very musical--perhaps not the best sub for home theater, but definitely very good in a hi-fi stereo setup. I have the sub in a forward-firing 1.8 cu. ft. sealed enclosure (I'd highly recommend a sealed box over a vented one--in my experience it has a flatter, more balanced sound). In this enclosure, the sub is very articulate and detailed, not overpowering, and overall it delivers a very pleasant sound with the two 6" bookshelf speakers I built. I'm currently driving the sub with a 1000 W RMS Klipsch amplifier, so I'm a little tentative about driving the sub too hard, but so far I've been impressed with the amount of output I can get from this unit.In short, if you're looking for a nice sub for musical applications, look no further. I've tried some car subs for past projects, some much more expensive than this Dayton unit, and by far this Dayton sub takes the cake for sound quality. For the price, this sub can't be beat.

Rated 5 out of 5 by from Nice speaker, great value, shakes the houseThis is a nice product. The speaker is heavy and built very well. The speaker performance is very solid. The only issue is that you need to drill out the holes to fit the mounting bolts,they are smaller than the bolts but that isn't a big deal. I built a 2cu ft enclosure with the Dayton 240 amp. Very nice.

Rated 5 out of 5 by from Outstanding performance at a great priceWhile in the market to replace my sub's dead plate amp, I decided to also replace the 15" speaker as well. The enclosure is a 2.9 CuFt downfiring unit that was originally a BSR passive sealed sub setup. After replies on a home theater forum, I decided on replacing the speaker with a 12", and porting the box. WinISD (A GREAT free app for speaker building) told me that I needed two - 2" by 7" ports. After plugging in the values for multiple speakers, I determined that the Reference HF 12" sub was a VERY close second to the Titanic 12" model, (At least for my enclosure) and the price sealed the deal. After receiving the speaker I was astounded by the heft of the magnet! It had to be at least 10 times the size and weight of the magnet on the paper coned 15" I was replacing! About an hour later, after installing the sub and ports, and the BASH 300W amp I also purchased. (VERY nice unit, BTW), I hooked it up to my system and popped in Star Wars, Phantom Menace. OMG! When the LFE channel hit during ship flyby sequences, the floor shook, and my pant legs fluttered with the air movement! My wife, who isn't all that impressed with my techno-geek speak regarding my system and speakers, was visibly shocked by the results. My 5 year old was scared by the vibration! I still want to play around with a tone generator and the port lengths, to truly dial in the sound, but it sound great right from the start.An excellent product and excellent shipping costs as well! Well Done!

Rated 5 out of 5 by from One Amazing Sub!I had an old sub box (MTX SW2) that needed an upgrade. After much research I decided on this speaker to replace the down-firing original that did not have much to offer. I replaced it and decided the 100W OE amp had to go, too. What a difference just the speaker made by itself! It sounded so good I decided to replace the original amp as well with a Bash 300W. I could not be more pleased; it sounds great--plenty of low end and volume. It shakes the house big time! Thanks to the PE parts guy I spoke to on the phone, this was an excellent choice for a down-firing configuration. Thanks so much Parts Express for offering great parts for a great price. You don't have to spend a fortune (I found out) to get a really good sounding sub.

Rated 5 out of 5 by from Lotta sub!First put this sub in an old downfiring front ported Mitsubishi subwoofer cabinet because this was an ez switch, what a disaster, no luck at all. Decided to build a box to fit my HT center so I ended up with 17.5"x13.25"x19" used 3/4" mdf approx 1.85 c.f. internally braced, coupled with the older version Dayton 250W sub amp (P.E.)front firing. This puppy weighed in at 60lbs! The room is 16x16 with a valted ceiling. 1st config was a sealed box, outstanding performance for jazz and other detailed studio music but weak on live concert videos & movies. Of course box size & type has a lot to do with output. So I cut a 3" port 6" long on the bottom (D.F.), WOW, brought this thing to life! While watching a couple favorite scenes from Pearl Harbor my Levi's vibrated on my calves & shins along with the walls while my chest was being pounded by explosions or concussion! Output level set at aout 40% & crossed @120hz. For music, this sub brings out the full potential of the rest of your speakers, I was very impressed with the added detail to mains when going back to studio classic rock. Also the concert dvds put you in the front row! The bass is tight, plentiful & direct, this sub is a winner!

Rated 4 out of 5 by from Very musical contenderThis is an extremely tight and musical speaker. The fit and finish are very good, too. I'm using this driver mainly for music in a sealed 2.5 cu ft box with a 500-watt BASH amp. It's potent. Be sure to stuff the box with plenty of poly-fill.

Rated 5 out of 5 by from Solid build, Accurate,Output; as DesignedBuilt an enclosure 20"X20"X20" with a 13.5" long 3"diameter port tube and 240 watt plate amp. The results are an accurate output from 18 HZ up to 100 HZ as designed. This rattles the whole house when lower 20 - 40 HZ range is pumped in. This works well for both music and home theater applications.Built this for my son's birthday...he can't wait to get. Testing has be fun with it. Very nice unit.

Rated 5 out of 5 by from Great Musical SubThis sub will exceed your expectations if your looking for something that plays low with above average fidelity as the name states. But would not recommend for heavy HT use, it doesn't have the XMAX to play those low frequencies at intense volumes.

Rated 5 out of 5 by from Great for music and HTI am very impressed with this sub. It is in home-made sealed box roughly 1.6ft^3 well braced and sealed being driven by an sa240 (great amp, btw). First off, the sub is very clean looking, it is mounted in a box painted flat black and is flush mounted, the contrast between the two is very attractive. Second, the sound is incredible. Under normal loads and turned roughly 60% gain it will blend flawlessly with my speakers (The room is roughly 400sq feet and has a 15foot opening to the second floor of vaulted ceilings of the living room...the exact opposite of an easy room to fill) for any type of music including some of hte more difficult rock. Pushed with a high bass song, things begin falling, my electronics begin jumping up and down making annoying noises, and my ears start to hurt all with minimal to no distortion. I don't have a meter, but it goes quite low, especially for a small sealed box. I love this sub and am starting a 15" project with a 500wt. amp now also.

Dayton Audio RSS315HF-4 12" Reference HF Subwoofer 4 Ohm

I am thinking about building a subwoofer using the Dayton RSS315HF- `12" subwoofer in a 2.0 cu-ft sealed type enclosure. My question is would it be best to use the Dayton SP-500 plate amplifier or would the BASH 500 plate amp be a better choice?

Asked by: BigRon
Headroom is always a good thing when it comes to subwoofers. I would recommend the Dayton for this reason, plus it also has a built in parametric EQ to help flatten room response problems.

Will one of these do OK in a .95 FT^3 ported encloure at 36 hz. Or is that tuning much to high? WIll be running 850 RMS Clarion 7110

Asked by: jones3jd
In a volume that small I would recommend the HO version of this woofer instead. It will yield a flatter response with that tuning frequency.

I was looking at this or the Titanic 12" mk4 in a 2.0 dayton box sealed with a 500w amp. Which would be the better choice for 60%movies/40%music in a 16x12 room standard height?

Asked by: audiophizile
These are both very similar in response. They will both reach the low 20's in room and handle full RMS power to below 20 Hz, although the Titanic will have a bit more excursion clearance. If I were choosing, I would probably opt for the Titanic. You might also consider the UM12, it will take the best of both worlds and still work very well in that volume.

Isn't your BassBox "Sealed" ideal box volume incorrect? You list 0.71 ft3 optimum box volume with an f3 of 70 Hz.  Even in a sealed box an f3 of 70Hz doesn't make sense for this driver's TS parameters.  I have BassBox 6 and it is recommending 1.7 ft3.

Asked by: yotool
It appears the box alignments are wrong for this driver because I am getting the same numbers as you. I will have these updated on the site.

How much breathing room is required around the basket?  I want to build a box with as narrow a baffle as possible; I'd like to make the space between the side walls 11.1" to allow the driver to just fit.

The side walls should be no closer together than the required cutout size for the woofer. 11" will be fine.

The frequency response says its 23-1,000hz. Does that mean i cant or shouldn't play it below 23hz? Thanks

Asked by: lilquiids
This is just the free air resonance of the driver. In the proper enclosure this woofer can play safely below this frequency.

What would be a better plate amp for this driver? The dayton audio 250w or the dayton audio 500w? 2 cu ft sealed enclosure. I will be using it for 50/50 music/movies, thanks!

Asked by: lilquiids
I always recommend headroom with subwoofers. I believe the 500 watt amplifier would be a better choice.

I have a 3.8 cu ft sealed enclosure in my home studio. 300w @ 4ohms plate amplifier (keiga 5230) will this driver work for my application? suggestions? was also looking at titanic

Asked by: relaps
With the power you have available I would recommend this driver. It will work well in that volume and play into the mid 20's in room.

passive radiator for this subwoofer?

recently i bought this sub and its sitting in 1.55^ft sealed box, its sounds good, its a beast, but i want more low bass (for movies), which passive radiator will work best in same box?thank you
Asked by: gurgi
In that box the TC Sounds VMP 12" will be the best. With no weight added you will have a tuning frequency in the low 20's and an F3 of about 32 Hz.

Do I need gasket tape/caulk?

I received my driver and noticed it has a foam ring on the back side of the flange, however with no adhesive. Will this function as gasket tape or do I need additional sealing to ensure it is airtight?
Asked by: lallen
The foam on the back of the frame is all that is needed for an air tight seal.

Is the optimal cutout for this 11.10" ?

I know that it seems silly, but mine didn't come with any mounting diagrams or guides. It says 11.10" here on the web site, but I am measuring slightly different than that, but then again I am not 100% sure how it *should* fit. I don't want to make the wrong cut in my MDF and don't have much scrap to even test cut first. I will be using a nice circle jig and router, but want to double check. Thanks.
Asked by: nickbuol
Yes the cutout is 11.102". In my experience you always want to do a test fit on a piece of scrap anyway. I would personally start with a 11-1/8" hole which is 11.125". This should give you just enough wiggle room and still have plenty of meat for the screws.

Will it work in a Generic ported enclosure?

I plan on purchasing two of these and installing it in my living room, however, I am having trouble on building a vented enclosure or finding one tuned to the recommended freq. and size.I was thinking of buying a generic subwoofer enclosure usually used for car audio (I understand that its tuned a little higher, around 30+hz) and try to find one that has around 1.7cu ft. + of volume per chamber.Will it affect the quality of bass that much?
Asked by: maxpowers
I would not recommend using this in a generic enclosure that is vented, this will create a rise in the response at the tuning frequency and will basically eliminate all low end. These enclosures are actaully tuned closer to 50 Hz. If you want to use a generic enclosure I would recommend sealed only, around 1 cubic foot.

What be the idea size and port size using the SPA500 Amp ?If like to stay at 25Hz?Or which web provide the simple way understanding?
Asked by: woodknight
I would recommend 4 cubic foot (after displacement) with a 4" diameter, 10" long port for a tuning frequency of 25 Hz. i would personally lengthen the port to 17" for a lower tune especially if this is for movies.

Can this speaker be used in a down firing configuration?

Asked by: monomer
Okay, answering my own question I know makes me look like a dumba$$ but this is what I've found after a little research... referencing the resource here at PE ... where the calculation (using either one) yields a 2.78% sag for this particular driver. Accordingly the resource article says if the driver in question has a sag under 5% then it should be alright to use in a down firing configuration.

What is the spl db at 2.83V/1m?

The the 12 inch Titanic has the spl listed at 89db at 2.83V/1m and this sub is listed at 86 db 1w/1m with the 8 ohm version at 84.5 db 1w/1m. What is the spl db at 2.83V/1m for this 4 ohm sub and the 8 ohm version as well?
Asked by: cavemanmusic
At 2.83Vrms, the 4ohm version produces 89db. The 8ohm version at 2.83Vrms does as rated.

Would you recommend as a woofer

I may use this driver as a woofer rather then a sub-woofer. It would be crossed over at 300Hz. Would you recommend it?

300hz is well within it's usable range, I think they'll work great.

Outdoor application under my deck with lots of power....

I am looking at buying 2 of these for under my outdoor deck. I will have 700W RMS going to each and am curious as to the type (sealed or ported) and dimensions I should use for best output. I listen to mainly ROCK and RAP, so I want them to be loud but also handle low frequencies efficiently. I have seen and read about aiming the woofers toward the base of the foundation for better output. I am running 4 Klipsch AW650 outdoor speakers for full range and they sound amazing... just need some low end help. Your thoughts?
Asked by: Sessy Mike
Wouldn't recommend it. You need weather and water proof out doors speakers. There all sorts of bugs that love to feed on speakers.Look on page 16 & 18 of this yrs catalog you'll find some good out door speakers.

Open or closed for best musical response?

I will use this unit in a 3-way system where I would like to cross it over at around 250Hz, which is a bit higher than usual I suppose.To make this driver sound as "musical" as possible, is it best to go for a closed enclosure or is there no difference really with a ported enclosure besides the lower frequency extension?
Asked by: Maarten
for music, I always say closed. it has a much faster attack and is just more accurate and sharp.. you can get some good extention closed just a little bit larger. This sub with a powerfull amp will shake quite nicely

HO or HF for 2 cu ft sealed cabinet with SA240 amp?

I have the amp and cabinet, now I don't know which subwoofer would be a better choice. It will be used for movies and TV in our theater room which is 12'x21'.
Asked by: JTenn
Might work. This is the right woofer, really good speaker. But it's gonna want more space to breathe, + consider the amp takes up about 1/2 cu ft, so 4 cu ft minimum and port it.I use PVC tubing 2x 2x6" or 1x 3-4x5". For larger subs I use a toilet flange from hardware stores. They are cheap, paint-able, and look cool. Press fit if you cut the hole right.

Would swapping this speaker for the original found in a Dayton Sub-120 150 watt be a resonable upgrade for better sound?

Asked by: hoggman
Yes, it would. I believe this subwoofer box is sealed, and in it the RSS315HF-4 will be at a Qcb of approximately .770, with an F3 of about 36Hz. -6db at about 29Hz, and -10db at about 23Hz.It would be a bit under powered with this sub's amp, but it's an efficient subwoofer driver, and will likely play at a level more than good enough for most of your music and movie requirements.I own this driver myself, and find it very musical.

Is the impedance really 4 Ohm or is it less?

Did anyone measure the real-life average impedance on this sub?Reason for asking is that I want to connect it up to an 8 Ohm amp, which should be able to handle 4 Ohm as well but might give trouble with lower average impedances.Before anyone asks: the reason not going for the 8ohm version of this sub is that the 4ohm version is more flexible when it comes to re-using it in later designs.
Asked by: Maarten
Each speaker may measure slightly different. On average you will see 3.8 to 3.99 ohms on a meter with the speaker at rest. Impedance changes with frequency as well so the number is a reference point. You can use 4 as the number to calculate the impedance you are wiring to your amp. If it is 2ohm stable per channel then you can put two of these on that channel without fear.

Would 220watts min RMS run 2 of these at 8ohms and if not what would you recommend?

My power amplifier is a Kenwood Basic M2 have three of them and a M2A all of witch will produce min 220w at 8ohm and a 467w at 4ohm @ 0.004 THD. At the moment I am running 2 15" Kicker CVR rated at 500watts each sub woofer @ 8ohms each with one amplifier. and I am afraid of the amp blowing up

Yes, that will drive them fine.And as long as you are not consistently driving them into clipping, and they are well ventilated, you have no worries the amps will blow.Relax. LOL

which is better for a sealed home theater sub this or the ho version

60% music
Asked by: vander
In the Reference Series subwoofers, "HF" refers to "High Fidelity," where "HO" refers to "High Output." For mainly musical situations, the HF would be indicated. One is not necessarily better or worse than the other, they're simply optimized for clarity as opposed to sheer output volume. Both are very good.

Would this sub work as a car audio sub

I was told this would be a great sub for my car audio needs. I am looking for 2 subs to run at @2ohm total. I have a amp that output 650W RMS @12v. My enclosure is Q-Logic dual 12" enclosure, standard size.I know these are used primarily for home audio. Is there any reason they wouldn't be awesome in a SUV?
