Dayton Audio SD270A-88 10" DVC Subwoofer
Dayton Audio SD270A-88 10" DVC Subwoofer is rated 4.7391 out of 5 by 23.
Rated 5 out of 5 by from ReplacementBought this subwoofer to go with my new plate amp and with some slight alterations fit in my AR cabinet.Sounds great gave me back some great sounding bass.

Rated 2 out of 5 by from Base Replace-mentI bought a pair of these to replace my 28 year old Kenwoods, but, was disappointed in their sound. The old speakers with deteriorating and taped up suspension foam, had more bass than they did, sorry to say. I was refunded promptly however.

Rated 5 out of 5 by from solid performerI got a pair of these 3 years ago. Still today, these sub put out plenty of low end bass. They were put in to a sansui sealed box. Not sure of the cubic inch. But with a bass test cd, I know they get to the bottom hertz. I've heard the same cd on many other systems. These subs have hit as low as some 12s that I've heard. Overall very pleased with performance.

Rated 5 out of 5 by from Nice sub at a great price!I bought this to match with a Dayton 12" PR in a relatively small box (1.35ft3 net volume, light fiber fill in box, no weights added to PR). The build quality is quite nice for this price range, sound quality is really good and in my setup, with the matching passive radiator facing the wall, it digs deep and has surprising output with only 150w. I've been listening to this setup for the past month or so in my workshop so it's seen 8-10 hours a day and is a pleasure to listen to on any type of music. This combo offers performance way beyond it's price point.

Rated 5 out of 5 by from Quality > PriceIts price and quality is not equal. Quality tops over its price. I have two of them and its pretty nice. Way worth its price.

Rated 5 out of 5 by from Much Better Than ExpectedReplaced the failed driver in a Cerwin-Vega HT-10PWR that I have been using on my computer with this one. For the price I wasn't expecting a lot, and after opening the box and comparing with the old driver, I was expecting even less. The old driver had a cast aluminum frame and weighed about twice as much as the new one. Of course the real comparison is how it performs. This driver seems to be a perfect match for this sub, it has as much or more output and better defined bass but, the real shocker for me was the absence of port noise. Don't know enough about this stuff to explain the lack of port noise but, this driver transformed this sub to perform better in every way. Definitely much better than expected.

Dayton Audio SD270A-88 10" DVC Subwoofer

Would the da 70 watt plate amp power this subwoofer ok. Or would I expect small results from the small amp.

Asked by: joEy B34
The SA70 will be a great match for this woofer.
Answered by: MattP

What sort of power handling and sensitivity would I get with this sub in a 1.3ft^3 (37L) sealed box?

Asked by: Darksteel
Sensitivity will be the same with or without the box. This woofer will handle up to 60 watts without excursion problems in that volume.
Answered by: MattP

What is the best box volume and port (single port) size for a downfiring subwoofer for F3 not higher than 30hz. is it going to give solid deep bass with car subwoofer amplifier? (200Watts 4ohm application)

Asked by: markpen883
The recommended volume for this woofer is 3.9 cubic feet with a single 3" diameter port that is 6-3/4" long. This will provide a tuning frequency of 23 Hz and F3 of 27 Hz.

Internal dimensions for sealed boxes are 9.5 x 12 x 17. I am getting 1.122 ft3. Will this work with this sub? Should I add any insulation?

Asked by:
That volume will work with this sub. We recommend about a half pound of stuffing per cubic foot of airspace.
Answered by: MattP
Date published: 2014-08-04

Can a lower frequency be obtained in a different sized sealed box? Is the f3 suggestion the best way to go and do I need to subtract the subwoofers mass from the f3? Also is the f3 suggestion for the 12" version accurate because it is a higher fs?

Asked by: buttchz
You can achieve a lower Q by putting this in a larger enclosure which will help the low end a little but not much. The volume online is total and is what the box needs to be built to. Yes the F3 of the 12 is accurate.

Is this the same driver as SD270-88 sans shielding? The reason I'm asking is that I currently use two SD270-88 per side in an open baffle, and they sound great. But I want two more per side for lower excursion and higher output capability.

Asked by: SweDavid
Yes these drivers are virtually identical in terms of performance. The overall sensitivity dropped a touch without the bucking magnet to aid the motor strength but this should not be a deal breaker.
