Dayton Audio SD215A-88 8" DVC Subwoofer is rated 4.7667 out of 5 by 30.
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.
Date published: 2014-09-25
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.

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.

Building a sub to fill in lows for W3-881SJF bookshelf speakers. Planning a 4th order bandpass using a 10" PR in place of a port.  This appears to give a flatish response to about 25Hz at expense of gain.  Will the speaker survive this treatment? 25W amp.

Asked by: Deadbugs
Yes this woofer will work fine for low to moderate volume levels. I don't see there being a problem with only 25 watts.

Hey guys, If I buy 2 of Dayton Audio SD215A-88 8" DVC Subwoofer what kinda Amp would I need to run them. Do you guys have links to some?

Asked by: Dro121
The type of amp depends on if you are powering both together, or separately. If you are powering them together, something like the Yung SD200 would suffice, providing about 100 watts RMS or so into an 8 ohm load. If they are being powered separately, the Dayton SA70 would work very well.

What would be the best box design for one of these for listening to mainly rap/hip-hop and some EDM? Or, would this be a good subwoofer for this purpose? Doesn't need to be stupid loud as its a $30 subwoofer, but i'm looking to add a decent sub to my dorm

Asked by: Tim H
I would recommend a 1.3 cubic foot vented box using our part number 260-478 for the port. This will tune the box to 30 Hz and provide a good mix between output and extension.
