Dayton Audio SD215A-88 8" DVC Subwoofer
Dayton Audio SD215A-88 8" DVC Subwoofer is rated 4.6571 out of 5 by 35.
Rated 4 out of 5 by from 2001 Suburban SLT - factory sub upgrade.I purchased this to go into my 2001 Chevy Suburban SLT that had a stock 8" sub location, I need some space back so I removed my Dayton 10" in a 1ft³ enclosure. I wanted to use the stealth, stock location and still retain some low end.Well, it does not fit a 2001 Suburban SLT stock sub location without a handful of mods. Some reviews online state it does, however, that is not the case, but also not the speaker's fault. It takes a custom mount, all made from parts of the stock sub, to fabricate a mounting system. Have some rope seal available to use between the mounting system parts to stop air leaks and isolate the parts from one another. The stock sub box is too shallow by almost a 1/2" so the magnet hits the back wall, plus it needs @3/4lb of polyfil inside, and MLV on the interior and exterior surfaces to stop the ringing/vibration. You will also need longer screws since you must space the sub further out. Once I fabricated the baffles and gaskets, plus a mounting ring made from part of the stock sub's basket that I jig sawed apart, it sealed well and there were no air leaks around the mounting points. The fabricated mounting ring basically "sandwiches" the sub and baffles down to the stock sub mounting surface.I wired the dual voice coils for a 4 ohm load so that the sub has up to 75-80 watts of power available from my amp. Crossed about 80hz it is doing a very nice job of adding enough low end to the system to satisfy, and matches nicely with the 6.5" components in the front doors. The speaker surround does not hit any part of the stock grill while playing hard, very nice. Cabin gain picks up the lowest octaves nicely in these big Suburbans, so it digs deeper than I expected. If this had been a drop in replacement it would be perfect. As it is now, it is doing a satisfactory job! Plus I gained back some space since we haul 4-6 people around to weekend long soccer tournaments and games, and I need max cargo space for all the travel stuff. For around 40 bucks at the time I purchased, it is very impressive.

Rated 5 out of 5 by from Get it. Wait, don't. I need more.I put this in a 1 cubic foot ported fiberglass enclosure in my Corolla, feeding it 180 watts. It's great- meaty, defined, impactful bass. A bargain.

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.

Dayton Audio SD215A-88 8" DVC Subwoofer

I'm looking to use this driver in a box with 1.06 ft3, which has a 7" long port, and is 2.5" in diameter. This is my first DIY subwoofer, and I'm wondering if this would work and how low it might go. Would part # 264-854 be a better choice? 

Asked by: Dutchboy
The SD215A-88 would be a better choice for this enclosure. The port tunes that volume to 38 Hz.

In a box that is 1.16th what should the port size be dia & length for 45 hrtz 

Asked by: Pete345
A 3" diameter 7" long port will tune to 45 Hz, but I would strongly recommend a lower tune in this volume. A 2-1/2" x 8-1/2" port will tune to a flatter 35 Hz.

When I load these parameters into Bass box pro I get a suggested volume of .313 cu. ft. Do you have the file you used in BBP so I can see what I did wrong? Also, what port parameters do you recommend? thanks, Nick

Asked by: barderer
We use the high fidelity option in our models. It looks like the high output selection shows a volume similar to your numbers so I would double check your alignment settings.

Hi, what would be the net volume if wanted to use this sub with the 10" passive radiator? Any additional weight added? Thank you! Rony

Asked by: Rony
I would recommend 1 cubic foot and 50 grams added to the passive for a tuning frequency of 35 Hz and an F3 of 38 Hz.

Will this sub offer good performance as a replacement in my Infinity PS8 enclosure?

Can you recommend optimal box size for using this with 2 of the Dayton 8" passives? Seeking lowest possible F3 in a compact cabinet. Additional mass on the passives too?

Asked by: Zdog
I would recommend 1 cubic foot for this, with 75 grams added to each passive. This will tune the enclosure to 30 Hz.
