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

wil it work ok in a 1.5 ft3 sealed enclosure? Wil it go down to 20 hz (-3db)
wil Dayton Audio RSS315HF-4 12" Reference HF Subwoofer 4 Ohm work ok in a 1.5 ft3 sealed enclosure? wil it work ok down to 20-25hz?i already have a 1.5 ft3 / 42.5 liter sealed enclosure.

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!
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
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.

if I want to use two these for hi-fi stereo application using an active crossover, not for car audio or HT, what type of enclosure is recommended? Ported or sealed? if ported, what dimensions?
The recommended enclosure for this driver is 2 cubic feet sealed, with 300-500 watts RMS for the driver.

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
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?
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.
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?
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 sized sealed box is the best for these sub-woofers to get the lowest F3?
I currently have two sealed sub boxes that have inside measurments of 13 inches x 13 inches x 22.75 inches. Will these boxes work withthese sub-woofers and how to they rate with reagrds to F3 when compared to the optimal sealed box size for these seakers?
These subwoofers are ideal in 2 cubic feet sealed.

With SPA500 Amp plate ported enclouse
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?
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.

HiIs there any mounting kit with T-nut that I can use rather that the stock screw?Chance of frequent remove the amp plate.
Sorry for the misleading,actually the question is asking regard the Dayton SPA500 Amp plate mounting hole.

Can this speaker be used in a down firing configuration?
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 http://www.parts-express.com/resources/woofer-mount-up-down.cfm ... 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?
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.

Will the 4 ohm sub give me more volume then the 8 ohm version?
This is assuming that I am using the Dayton Audio SPA250 250 Watt amp.
"156 watts RMS into 8 ohms"..." 252 watts RMS into 4" yep

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?
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.

Volume of sub?
Hi, through guesstimates I'm getting a displacement of 0.1 cubic feet.

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?
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'.
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?
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.
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
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?
Due to the available power that you have on tap, I'd rather recommend the Dayton Audio RSS315HO-4 12" Reference HO Subwoofer listed below.
