Product Details

Dayton Audio RSS315HFA-8 12" Reference HF Subwoofer 8 Ohm

The Dayton Audio Reference Series subwoofers take the quality and performance of the much acclaimed RS line into the subwoofer realm. As with the rest of the Reference Series, the main focus of the RSS315HFA-8 12" driver is ultra-low-distortion. Second, third, and intermodulation distortion are kept extremely low by utilizing three magnetic short-circuit paths within the motor structure. A durable aramid fiber spider and extensive venting throughout provide quiet and uniform excursion. The black anodized cone, rubber surround, and custom basket give this driver a unique, high-end look. Choose this High Fidelity (HF) version for home speaker systems when your priority is clean, low bass and you are not restricted by cabinet size.

Dayton Audio RSS315HFA-8 12" Reference HF Subwoofer 8 Ohm is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from bad a** and wow!I used it in my surefire/bob carver box and it sounds awesome! the stuff rattles off my walls. It may be better than the original.

Rated 5 out of 5 by from Great SoundI matched this driver to the Dayton 2cu ft cabinet, and what a great combination. I am using only one channel (125W rms) of a backup amp while my dedicated sub-amp is being rebuilt, but wow even with only 125w pushing it the bass is nice and low and even (not thuddy) at medium volume levels.I am choosing not to port the cabinet for now since the bass is so tight and smooth. There is some drop off at very low freq but I was expecting that with this setup and no port.Music sounds rich and full and this is what I bought this unit for (paired with Mordaunt-Short satellites). Movies also sound great although I can't get the really intense bass yet as 125W is not enough to shake the house.Overall excellent bass driver.

Rated 5 out of 5 by from excellent sub for 8 ohm applicationsI am using two of these in seperate cabinets due to the odd shape of the room I am using them in. I am using these with a SA1000 Dayton outboard amp. These units perform very well together. The manual for the amp states not to go below 4 ohms so i chose these drivers. I originally used them in a 3 cubic foot sealed enclosure. I have since ported the cabinets (first one and then the other). They seemed to work well in both applications. I use them for movies, but mostly for music. I am very pleased with the overall performance. As you can imagine, I do not lack any bass response.

Rated 5 out of 5 by from great soundi matched this speaker with the dayton 240w b amp and it sounds really great...at first i was thinking i should have went with a more powerful amp but i tried the 2 together in a 2.5 ft sealed mdf box and the bass is punchy and low even at low volume, i am very pleased on the sound quality and the wall shaking capabilities of it all...i gave the value a good just because i'd wished i could of got it on sale, still a great sub speaker...

What is the height of the surround above the faceplate? My cabinet grill is 3/4 MDF but I think that may not be deep enough if I don't recess the drivers. Specs on Dayton's site show the faceplate is 3/8 deep. Trying to leave room for excursion

Asked by: SMF2k

I have an existing enclosure of 3.5 ft which previously held two Eminence DVC12s. The box is a heavily braced sealed design. I was never happy with the Eminence drivers. Are these drivers the best upgrade available? What would be the f3 and f10? Amp?

Asked by: SMF2k
These drivers would be an ideal choice for that volume. The F3 would be 40 and F10 Hz would be 23 Hz. I would recommend any of our Dayton 1000 watt amplifiers for this application.

Is this driver suitable for a open baffle dipole configuration ?

Asked by: ths61
This will work decent in an OB or dipole design. The bottom end will need some EQ to get the most from it.

If this sealed sub calls for 1.5 cu ft and you want two in a box, how many cu ft should it be? Any considerations for making them both front firing (vs. opposed to each other)?

Asked by: jhgkak
When using two drivers, the box volume doubles. The orientation of the drivers will not matter, but a dual opposed design will cut down on cabinet "rocking" at higher volume levels. For a home application, two separate subwoofers are better than two in one box for room placement options. This helps smooth out room nodes and peaks.

Looking at RSS315HFA-8 to replace a NHT1259 that just broke. Was in sealed cabinet 3.9 cu ft but never very happy with low end, read in the reviews and the specs how this speaker works well in either and good lows. Suggestions changing to ported box?

Asked by: LoudMscTH
I would recommend porting the enclosure using a 4" diameter Precision Port that is 17" long for a tuning frequency of 20 Hz.
