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 Great SubwooferI've been in car audio for a few years and this was my first home audio subwoofer. I can say that I am very impressed with the response and output of this subwoofer. The build quality is very nice as well especially being around the mass amounts of subwoofers I've seen at competitions. It is in a 5.05 gross/ 4.53 cuft net box tuned to 26hz. The amp I have on it is a SPA250. I love it for movies and it is also great for music. It shakes everything on the walls. It kills the lower notes too on some of my songs (23hz)

Rated 5 out of 5 by from Better than the TitanicI got this item on exchange for a defective Titanic unit. I had two Titanics (MK III versions), and also purchased a second Reference sub, so that I have two matched drivers in my two cylinder-design enclosures. (The Titanic is going into still another cylinder that I may give to a relative.) The Reference is better than the second, non-defective Titanic, too, making less flexing noise (ticking) when pushed even moderately hard. Yes, it lacks the x-max of the Titanic, but in my home-theater installation (and with two operating nicely down to 20 Hz) that is no big deal. I also have two other Reference units in a second system in another part of the house. (These are in larger enclosures, tuned to 18 Hz.) That rig is used strictly for music. I would say that for automotive use (where flexing noise is no big deal) or for home theater (where explosions might require a large x-max and musical content is not critical), the Titanic is OK. However, for serious stuff the Reference is better. Of course, I have not experienced the new MK IV Titanic, and so with that one all bets are off.

Rated 5 out of 5 by from Punch and Deep Bass- Ok, I didn’t know I was gonna get Punch and Deep Bass at the same.. i was using a Sealed enclosure at first and this Driver sounded Great , now i have it in an Awesome Transmission Line enclosure designed for my single 12″ Subwoofer.. i use this in my car audio system.. if you want clean hard hitting bass, this sub will do without backing down ... go easy on it at first to allow break in period , sounds even better as it breaks in.

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!!!

I want bass +- ~3 dB from 28 Hz to 70 Hz for music listening in a ~1300 ft3 room to go with a RS621 pair. I like left and right woofers for sound space; one might do. Should I get this 12" or two 10"? Cabinet volume? Vented?

Asked by: Bela81
Two woofers are always better than one for smoother in room response. A pair of 10's will reach 28 Hz vented, but a pair of 12's will do it sealed. A 2 cubic foot box will work fine for the 12's, the 10's will need 2 cubes each, with a 3" diameter dual flared port that is 15" long for a tuning frequency of 25 Hz.

Prefer to power this sub w/Dayton SA230 based on $, phase & other avail. adjustments vs the 500w plate amp. Previous post recommended a 5cu/ft ported enclosure w/4" dia & 17" long port. Recommended amp combo & enclsre for tight music/theatre to ~20hz?

Asked by: Adam in Omaha
The previously recommended enclosure volume and port will work well for music and home theater applications and reach 20 Hz without much of a problem.

I would like to build a dual opposed sub with these drivers in a 4 cuft box. This would be for a near-field placement between two recliners with the drivers facing each recliner. What's the minimum recommended distance between the drivers?

Asked by: darrellh57
I would recommend at least one inch of space between the driver magnets.

Would 100 watt Mrs @ 4ohm be adequate to run this for home theater and music? Tia for the advice

Asked by: Jones1911
In order to get the most from this woofer you really want 350-400 watts RMS. You might be farther ahead using a more sensitive woofer like the DCS305-4 in a vented box which will take that 100 watts farther. The DCS305 in 3.5 cubic feet with a 3" diameter, 10" long dual flared port will reach 21 Hz and over 110 dB output with 100 watts, the RSS315HF in 1.5 sealed will only have an F3 of 42 and reach about 104 dB output with the same power.
