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.

When hooking this up to the SA70...should it be wired in parallel to both VCs, series or just one terminal to one VC? thanks for you time.

Asked by: NJmike
I would wire the coils in parallel for a 4 ohm load to the amplifier.

I own two of these with the passive radiators as well. I need to build a box and I wanted to know if I could use a single chamber for both subs and the PRs?

Asked by: nicestereo
Having them in one or separate chambers will not matter. We do recommend bracing the cabinet, which is the only benefit to having two separate chambers.

For use with the dayton 12 inch passive radiator? Looking for sound quality but want it to dig down deep into the 20 hz area.. how would I build it with the PR? 

Asked by: AndrewsCarr
A relatively low tune is doable with the 12" PR, but the volume of the box would need to be about 3.7 cubic feet. With no weight added, a single PR will tune the box to about 28 Hz.
