Dayton Audio SD315A-88 12" DVC Subwoofer
Dayton Audio SD315A-88 12" DVC Subwoofer is rated 4.5714 out of 5 by 14.
Rated 4 out of 5 by from 5 screw holes...really? No, I mean, reallyThough the speaker worked fine in my intended application, I was floored when I first put the speaker in the cabinet. None of the holes lined up, except one, as there were 5 holes for mounting the the speaker to the cabinet. As this was a DIY project, it was no big deat to drill new mounting holes, but really? 5 mounting holes. Who approved the tooling on that?

Rated 5 out of 5 by from Great Sub Great ValueReplaced a Cerwin Vega 12" DVC sub with this and I have to say it sounds as good or better. The CV sub voicecoil completely separated from the speaker cone about halfway through the latest Mission Impossible while they were blowing up the Kremlin. In addition to the Kremlin my speaker blew as well!!! HA!! Wondered what that loud pop was!!

Rated 5 out of 5 by from Awesome Subwoofer, Floor ShakingA very powerful and cheap subwoofer! It is a very simple subwoofer with decent power handling that provides lots of bass. I power it with the Dayton Audio SA100 100W Subwoofer Amplifier and it has more then enough power to make the floor shake. I like the dual voice coil it provides lots of options and good power rating at a low cost. I have it in a custom enclosure made from a old red wing crock with a "lid" on it to house the sub. I like it a lot it was the final piece in my surround sound system and works well with my other speakers. The plate amp has a gain level dial to match levels. My favorite song to play on it is Video Game by Lana del Ray the bass sound very nice and is exactly what I needed.

Rated 3 out of 5 by from You get what you pay forI ordered two of these and they both had bent frames on arrival. I straightened out the frames and used them anyway, because I live on the other side of the world to PE HQ. The voice coils did not measure 8 ohms each but 5.7, which made the use of a passive crossover with both coils active very troublesome. I ended up having to drive each unit on just one the the voice coils. The response and performance is acceptable, but not great. I should have spent more money on a different product. They do look nice though...

Rated 5 out of 5 by from Couldn't ask more for the price paidI have been very impressed with this sub over the last six months. For the price I don't think you could ask for more. I built the vented enclosure that the parts express staff provided from the bassbox software (Specs under Q&A section) paired with the dayton 240W plate amp. Exceeded my expectations!

Rated 5 out of 5 by from Kappa 7 ReplacementReplaced the bad woofers in a set of Kappa 7 speakers with these subwoofers. Needed 4 ohm and the specs show they go lower than the originals and upper frequency response was well past the crossover point. Speakers sound awesome! Excellent low bass extension. I am sure they will sound even better after a little breakin period. Outstanding value!

Dayton Audio SD315A-88 12" DVC Subwoofer

does the 2.4 cf recommended in one response include the port volume?

Asked by: Jimbo slice
Yes it does.

is it possible using resistors to make this 12Ohm?

Asked by: speakerfreak1
Unfortunately no, adding resistors is not the right way to raise impedance of a driver. They will also greatly reduce output by dissipating majority of the power as heat. You would need to find a driver than is rated for a 12 ohm load.

With a 180 wt marantz amp, would two of these, in a down firing sealed box, sound better than a single Dayton classic in a down firing sealed/ported box? I prefer tight musical bass but will be used for HT also.

Asked by: Shifty Switchblade
A pair of woofers will provide more output and better room coverage assuming they are in two separate enclosures.

box size for an F3 in the high 20Hz to low 30Hz range? i was thinking 28Hz

Asked by: speakerfreack
I would recommend a 2.4 cubic with a single 3" dual flared port that is 10" long for a tuning frequency of 27 Hz. This will provide in-room response into the mid 20's.

Asked by: Ronnie31

Now, this is an unorthodox question, but I was wondering how these would react in a fully deadened car door. I've been thinking of either using the door cavity as an enclosure, or building a fiberglass sealed enclosure. Which would yield better results?

Asked by: MattOC
These would not act any different in a sealed car door than they would in a sealed enclosure of the same volume. The door will be more resonant but you could expect low 40's out of these in a sealed car door.
