Dayton Audio SD270A-88 10" DVC Subwoofer is rated 4.7273 out of 5 by 22.
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.

Rated 5 out of 5 by from Really woke up my Kenwood 103SWSo I have been a "budget" audiophile for a long time. I have owned this Kenwood sub for a long time and the sigma servo branded woofer in it did a decent job for years. Well like all foam surrounds; the one on the sub gave up the ghost. So what to do? I decided to give this budget Dayton a spin... I mean it's under 50 bucks, what was there to lose? Well I was pleasantly surprised. The 8 ohm DVC was a good match for the original 4 ohm woofer once I wired the coils in parallel. Luckily the cabinet is tuned to about 25hz and the port tube is flared at both ends. It's no thousand dollar sub; however, it is much cleaner than the previous setup. The low end extension is actually pretty effortless given this price point... I keep it crossed at 55hz on a 24db/octave slope since it is pairing with my koss cm1030's... It disappears correctly and becomes just an extension of the already spectacular speakers in play. Maybe it's because there are 3 10's; maybe it is just better than it's price suggests... you make the call... there isn't much to lose here.The only con I can see with this inexpensive little jewel is the fact that the mounting pattern is somewhat odd.. It is a 5 screw affair and most of my gear have 8... had to redrill the mounting holes for this one. Not really a con; but there has to be something realistically negative said, right?

Dayton Audio SD270A-88 10" DVC Subwoofer

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.

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.

I've had a pair of these for a few years now. They perform great. I'm lookin to do a diy and was thinkin of the dayton designer 5" and dayton 1 1/8" silk tweet. Seein the subs fs so low; would it work well in a  vented size box but without the port? 

Asked by: David2682
You will have to elaborate on "vented sized box" since this could mean about anything. These will work pretty well in either type enclosure but the volume of the box will determine how low and loud they will play.

What would the volume of the box need to be if I plan on using the matching 10" passive radiator with this sub? Also would this sub function well in a down firing configuration? 

Asked by: JoshA
The recommended volume for this woofer and the matching PR would be 3.8 cubic feet with no weight added to the PR. This provides an F3 of 33 Hz and a tuning frequency of about 28 Hz.

Looking to run 16 of these into a 1 ohm load is this possible?

Asked by: swishahouse6
Yes this would be possible. You will need four sets of four each wired to 4 ohms, then all four sets wired together in parallel.
