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 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!!!

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.

I see you have provided ideal vented box volume in your spec area but you haven't mentioned the port area/port length needed for the ideal ported enclosure. If you can give a flared port with part no. available on PE website for 4.54 ft.³ vented box.

Asked by: Kushagra
I would recommend a dual flared 4" diameter port that is 17" long in order to achieve the F3 numbers on our site.

Help! Opinions needed for music only application for stereo sealed subs and have 400+ watts/channel. My question is which sub to use, the RSS265HF-4 10" or the RSS315HF-4 12"? I am using an electronic cross integrating them with a mtm scan-speak 5'' kit.

Asked by: Chris1970

Will the RSS315HF-4 12" Reference HF be a suitable replacement for my driver from my Atlantic Technology 172 PBM. It is a sealed system with a 150 watt RMS Class G amp. The enclosure outer dimensions are 19.5" x 13" x 13.5". Primary use is home theater

Asked by: vinman
Yes this will work in that volume without a problem. You may want to upgrade the power eventually, but 150 watts will work for decent output levels.

Would this subwoofer driver work in an older ported infinity bu2 subwoofer with a 100 watt amp?  Not sure of enclosure measurements. Also looking at the classic subwoofer. Which would be better for my application?

hi, with what passive radiator do you recommend to use with this speaker in a 3 cuf box? thanks.

Asked by: asher
The best PR option for this woofer in that volume would be the TC Sounds VMP 15". With 460 grams of weight added, the tuning frequency will be 27 Hz and the F3 will be 28 Hz.

How much volume in the cabinet is taken up by this woofer if mounted flush in 3/4 MDF?

Asked by: Box Builder
When flush mounted in 3/4 MDF this would displace 0.114 cubic feet.
