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 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...

Will these work in a lab sub?

Asked by: Anonymous
These have never been tried as a replacement for the Lab 12 driver. They will probably work, but there might be lacking performance compared to the Lab 12 driver itself.

I just sent a question in but had the wrong information.  The box is sealed 5.36 cu ft.  15" passive radiator, 450W amp.  I had a Shiva MK 3 12" woofer that is now kaput.   Is the Dayton 12" subwoofer a compatible fit?   if not can you recommend one?

I am confused, it says a large sealed enclosure but list 1.54cuft...  I want to use this in a high end studio, we have no limits on size and placement.  Be interested in using real studio foam inside vs the cheap stuff.  Suggestions?..

Can't get win isd to work for me, could someone tell me how this would do in a 3 cu.ft. box accounting for driver and dayton 500w plate amp volume?  

Asked by: albey
Assuming sealed, this volume is about twice what is recommended but it will still work. You would have an F3 of about 39 Hz and in room response into the low 20's. You will want to watch cone excursion at low frequencies in order not to damage the woofer.

Any Body Have a recomendation about an Enclosure my space is a staud bay Deep wall 48" Hieght,13.5 wide 12" deep Can I make a box To fit that space I will be using two of these with outboard amp home theater aplication

Asked by: Curranav
The amount of space you have to work with will be plenty for a pair of these woofers. I would recommend leaving it sealed. The SA1000 amp would be a good choice to power them.

Can someone recommend a knock down cabinet for this subwoofer?  It will be used in a commercial space with an external amp.  thanks!

Asked by: dsmall
The best option for this woofer would be the 1.5 cubic foot cabinet below, which is pre cut for the 12" Reference woofers.
