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 Best subwoofer I've ever owned!What can I say about this subwoofer. But simply it's awesome! Bought a 4 cubic foot ported subwoofer box from and two 3" ports 24" long tuned to 20 hz. With a BASH 500s amp. Best setup I've ever had! Hits everything I throw at it

Rated 5 out of 5 by from Why is the house shacking???This was my first sub build and won't be the last. I used boxnotes and winisd for modeling to get the sub I wanted. Also a lot of guidance from the forums at HomeTheaterShack. I've got it dialed in and it's starting to get broken-in and soundingbetter every time I use it. I haven't done any REW testing but when the wife hollered down asking why the whole house was shaking using an inuke 1000 in bridge mode with the gain on 4 I knew I had accomplished what I wanted!!!

Rated 5 out of 5 by from Cialis for ED.. A2-300Replaced the stock ED A2-300 driver with this one and am very impressed with the results. No more bottoming out on bass heavy scenes and it sounds great with music too. Sub is finally living up to all the hype it received when I first bought it. Good build and quality and am very happy with the purchase.

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

what is the optimal enclosure size for ported sub?

i have this sub in a 5.1 cf box w/ 4 by 11 port. the combonation of the box & sub is too heavy. looking for something smaller like 3 cf or so. if you know the answer, can you give me the box size and port to use for optimal enclosure size
Asked by: KSHIZO
Hello: I have this driver in a net ~ 2.5 cu ft sealed box and it's fantastic sounding and quite powerful in a 22ft x 18 ft listening room. Exterior dimensions: 21" x 17" x 15" . 3/4" mdf panels braced vertically and horizontally w/ 2" x 4" and box stuffed with R13 insulation.Deep controlled musical bass. Quite satisfied with HT perfomance also. If you still think you need a ported design for more impact over musicality, try the enclosure design site - tweaking Qtc to lower than 0.707 to achieve lower Vb and balance out with db peak.

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.

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
Definitely the HF woofer. And definitely stay with sealed. The HO woofer doesn't look good in the airspace or in a sealed cabinet. The HO also needs a lot more power to get moving.This driver looks very good in 2 cu ft sealed and is flexible enough to move up or down a good bit (depending on if the amp will be inside the box taking up space). The response stays smooth down to about 1.6 cu ft and still looks good with as much as 2.5 cu ft. Two feet appears to be pretty close to the sweet spot though and with the amp you are running it will produce a lot more (and better) sound that one might expect.Looks like a good choice to me.

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
Assuming an adequately large sealed enclosure (let's say larger than 1.8ft, 2.3-2.8 would be ideal) vs. a vented enclosure tuned to 20hz (this would want to be big, 4-6 cubic feet) you get the obvious extension of low end - which is pretty significant below 40hz.The other effects of a ported enclosure (vs. sealed) will be port response phase, and the group delay between the driver and the enclosure or port's resonance. Down to around 38hz the group delay is actually better (lower) on a large vented enclosure - owing to the larger size of the enclosure and its "leak" (the port) - but this delay starts getting long under 30hz. Most wouldn't consider that a problem, because the duration of the wave itself is fairly long at these frequencies so relative to wave duration, group delay doesn't actually increase much at all (%)Phase, again remains superior on a ported configuration to below 28hz, down past that is an obvious phase shift - not one that will affect musicality.In summary, if I had 4 or more cubic feet to play with I'd definitely choose a large, low velocity port tuned around 21hz , because it would exhibit cleaner response above 40hz and drastically more response below 40hz with very little coloration.

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?
Asked by: Jim Banneck
300hz is well within it's usable range, I think they'll work great.

Whats the Big Difference?

Is there really a big difference between this and the Dayton Audio RSS315HO-4 12" Reference HO Subwoofer 4 Ohm?
Asked by: Tim 46528
The HF (high fidelity) subwoofers feature a two layer voice coil that has very low inductance and a lighter cone for music applications.The HO (high output) subwoofers feature a thicker cone and a four layer voice coil for high power home theater applications. They also work very well in small sealed enclosures.
