Dayton Audio SD215A-88 8" DVC Subwoofer
Dayton Audio SD215A-88 8" DVC Subwoofer is rated 4.75 out of 5 by 28.
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.

Rated 5 out of 5 by from Worked wellPurchased as a replacement for the sub in my SW-200. A little slight modding to the wiring and it looks and functions better then the stock sub ever did

Rated 5 out of 5 by from Tight, accurate, yet low achiever.In the title I mention its tight and accurate. The subwoofer is exactly that, the bass notes are dead on, drum kicks are hit with authority. What really impresses me, is that for an 8 inch woofer, its low end extension and reproduction is unreal. It hits low notes as its 10 inch big brother would. The free air resonance of 31hz is easily achieved and with the right size box and port-tune, its a deadly combo.

Rated 5 out of 5 by from Excellent in vented enclosureI constructed 2 enclosures, a .5 cubic ft. sealed, and a 1 cubic ft.vented (with a 2" by 6" flared port tuned to 34 z). Both sounded great, but I preferred the deeper bass of port. Surprising output for such an inexpensive driver!

Is this a good replacement for the SUB-800 speaker? Is it worth it? Thanks

Asked by: From Houston

How would this be ported best in a Part # 300-7068 (.67 cu ft) box. 8" Dayton SD215A-88 & The Daton 70W plate amp? Or should it be ported at all?

Asked by: Spaker
That enclosure is a little on the small side for that woofer, but it can work. With a 2" diameter, 10" long port you will have a tuning frequency of 33 Hz. You will probably have port noise at higher levels however. Your best bet is to use a pair of the matching 8" passive radiators with 75 grams of weight added to each for the same tuning frequency.

I need an 8" subwoofer dual voice coil for my 2007 Rav 4. Do you have any suggestions? I plan on trading it in next year so I don't want to spend big bucks.

Asked by: Powerhouse66
Assuming it will physically fit, this Dayton would be a good choice. A cheaper option would be the Goldwood below, but you will have to compare dimensions with the stock woofer to make sure either option will fit.http://www.parts-express.com/goldwood-gw-408d-8-poly-dvc-woofer--290-357

Hi, I would like to use this driver with a pair of 8" dayton passive radiators, and a 100watt plate amplifier. What would be the best volume for the enclosure? Thanks. 

Asked by: albertaustralia
I would recommend 1 cubic foot total with 50 grams of weight added to each passive for a tuning frequency of about 30 Hz.

What would be optimum port configuration to use this in the Knock-Down MDF 0.75 cu. ft. Subwoofer Cabinet ?

Asked by: zdog
I would recommend a 2" diameter, 8" long port for a tuning frequency of 32 Hz.

2 -1 configuration for a satellite system.  Bookshelf speakers =8 ohms. This sub can be 8 or 4 ohms.  Since there is no separate volume controls from the plate amp (Dayton SA25 25W), do I need to match impedance between the speakers?

Asked by: TandEsdoorman
In order to use this and the SA25 with two small satellite speakers, you will need another small amplifier to power the satellites. I would recommend wiring the sub coils in parallel for a 4 ohm load to the SA25 and use the speaker level inputs and outputs with a small 2 channel stereo amp to power the satellites.
