Dayton Audio SD215A-88 8" DVC Subwoofer is rated 4.6667 out of 5 by 33.
Rated 5 out of 5 by from Replacement of Paradigm Factory SubwooferAfter many years of faithful service it was (past) time to replace the failed Subwoofer in our home theater audio system. The cost to have replaced from the manufacturer was substantial, so looked into a DIY project.Parts Express' website was a God-send. The straightforward search tools made selection of a proper replacement a breeze. With some great technical assistance via phone, a selection was made, the replacement ordered and was shipped within 24 hours.Once received, it was a 30 minute DIY to install the new speaker and close up the cabinet. Job done!I am more than pleased with every aspect of the purchase process and especially the end result of great sound at a budget price. (1/6 of the cost of the factory repair estimate to replace).- Thanks Parts-Express team!

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.

I have a 23l cabinet sealed with room for 2 8" drivers.If I wire them in series parallel ,will a 200w 8ohm plate amp be fine and is the internal volume OK?

Asked by: Chrissy74
Yes that plate amp will work well for the application. The volume will also work well for a pair of those.

I would like to run two of these with an mtx amp. I would like to bridge the amp but it can only handle 4 ohms bridged. Is this possible? If so how do I run the wiring?

Asked by: 1jamin
You will have to wire the each set of coils in parallel and wire the two subwoofers together in series for an 8 ohm load.

I'd like to put this into a 5 speaker system in an antique radio cabinet. My thought is to run the lows from a pair of left & right 3-way crossovers into each coil. typical 3-way crossovers look to be in the 600-700Hz range. would this work?

Asked by: Tom17
Yes there would be no problems running it this way.

Hello! I have a box that I constructed that has approx 1 cu ft minus the driver volume. With two drivers sharing this box, 200wt RMS for each driver(parallel) should I polyfill it? Any idea the F3 of this config? It's In the trunk of a corolla. Thanks!

Asked by: 98corolla
With 2 of the drivers in parallel in a 1 cubic foot box, it appears to tune to 62 Hz with minimal or no damping material. Adding any additional damping material will push the tuning up to 66-70 Hz depending on how much is added. Please contact our tech support if you require additional help with this question, or 800-338-0531 x1.

what are the T/S Parameters on this woofer when the coils are wired in series rather than in parallel?i know it shouldn't make much of a difference, but if it does i would like to know.

Asked by: Ben Baker
The only parameters that will change with the coils wired in series will be the Le, Re, BL and sensitivity. The parameters in series are: Le: 4.64 mH, Re: 12.8 ohms, BL: 15.4 Tm, sensitivity: 84 dB.

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.
