Dayton Audio SD215A-88 8" DVC Subwoofer
Dayton Audio SD215A-88 8" DVC Subwoofer is rated 4.6562 out of 5 by 32.
Rated 5 out of 5 by from Very Versatile and Solidly ConstructedIs there anything this Dayton DVC eight inch low-cost wonder can't do? I first used it in a small sealed enclosure as well as an even smaller aperiodic vented box, both to provide a simple "one woofer" stereo bass solution. Building on those successes, I next experimented with two per side in a pair of recording studio monitors employing a somewhat unusual stuffed slot aperiodic vent. Powered by 200 clean watts per side, these vividly recreate a solid bass guitar bottom octave and the impact of a hard hitting floor tom. Now, I am planning to explore the extent of their SUBwoofer capability via a one driver, two passive radiator "cube."What's fun about these is being able to try things without spending an enormous amount of money. Even more fun is hearing their bass come to life -- from room-filling with 15 watts per 8 ohm coil as a two channel driver on up to chest-punching with 200 watts into dual drivers wired for a single channel as 8 ohms.More expensive drivers will exhibit less distortion along with less power compression. However, the SD215A-88 is unbeatable as an affordable, heavy-duty, all around performer. Best of all, they have let me implement some interesting ideas that have resulted in very acceptable, better-than-expected results.

Rated 1 out of 5 by from cheaply madeI bought this sub-woofer to replace the speaker in my old Cerwin Vega powered sub-woofer box.At first I didn't think it was working at all because of the low volume, it's 4 ohm just like the original but it has 2 places to hook up like a dual voice coil but it doesn't wire like a dual voice coil because I tried to wire it at 2 ohms for more volume and it wouldn't even work.Even one of the terminals had broken off tying to un-solder the wire because it's very thin and cheap like cardboard

Rated 5 out of 5 by from Great product, great price.What can be said. It's a Dayton Audio product, so the quality is there for the price point. Sub DOES fit in a 2000-2005 tahoe in the built in sub enclosure in the fenderwell.

Rated 5 out of 5 by from Good 'lil subWorks well with the polk psw-50 as replacement. Had to trim out opening some and is much beefier than the oem.

Rated 5 out of 5 by from Fantastic for the priceI used this driver with Dayton Audio's 100W RMS subwoofer plate amp for a small vented sub build. The combination sounds great at low volumes and can really crank (for a small sub) when you turn it up, with no audible distortion. One thing that wasn't clear to me was that each voice coil is 8 ohms (8+8), so the driver can be wired for 4 ohms total. For the price, you can't go wrong with this little driver for any small subwoofer project.

Dayton Audio SD215A-88 8" DVC Subwoofer

I would like to know if this subwoofer would be ok to use as a replacement sub in a ford expedition? The truck has a 85 watt stock amp at 4ohms, and a small enclosure. just wondering if it would sound ok? I like clean bass. Thanks

Asked by: JVIN
Without knowing the enclosure volume it is impossible to know what kind of response it will have. Chances are it is a better woofer than the stock woofer in general, and if you can get it to fit properly it should do reasonably well.

What is the smallest feasible box size for a sealed application where musical accuracy and transient response are the main concerns (hardly concerned at all with high output).  I have dsp available to make up for the early roll off.

Asked by: strander
The smallest feasible box would be what is listed online, 0.33 cubic feet. You could probably squeeze it into 0.25 which will help excursion, but you will still hit your limits with just about any EQ below F3. This would only be recommended for very low output applications.

I received this speaker and it fits into my sub box that's 60 watts rms but the volume is low,,the original speaker is about the same but single voice coil and 4 ohms. This says 4 ohms but I checked and my meter reads 6.6 ohms.  How to wire?

Asked by: MitchABQ
It sounds like you only wired one of the connections on this woofer. They are each 8 ohm, so you will want to wire the two together in parallel (+ to +, - to -) which will present a 4 ohm load to the amplifier and provide about 3 dB more output.

In the catalog this is listed as 8 ohm, here on line it says 4 ohm.  Can we clear this up ? Finding a lot of things like this. Online shows one thing, catalog shows different info on the same part. Thanks for any help in advance.

Asked by: KMAT
DVC = Dual Voice Coil--two coils per driver. Each voice coil is 8 ohms. The two coils can be wired together parallel to yield 4 ohms for the driver, or in series to yield 16 ohms. Each coil can also be used individually (two amp output channels into one driver), which presents an 8 ohm load to each amp output.

Compatible with Dayton Audio SA100 100W Subwoofer Plate Amplifier? Best wiring for DVC with this amp? In a 1cu.ft vented box (2.5" x 8" port as above?).

Asked by: BruceSUB
Yes this will work with that amplifier. Simply wire the coils in parallel for a 4 ohm load to the amp.

How would this do in a free air application such as in mounting it in a rear deck of a car? 

Asked by: gpa1
This will work reasonably well in that type of application if you aren't expecting huge amounts of output from it. This should reach into the low 30's pretty easily and moderate volume levels.
