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.

I have a dayton powered subwoofer and I blew the woofer. Can I use this to replace that one?

Asked by: dedcell13

I plan a build a down facing ported sub woofer cabinet with this sub. 1.25 cu. ft. Can I use this sub facing down?  I know in a previous question you said the SA70 would work well with this sub. Any benefit to using the SA100 plate amp. 

Asked by: Frank Glass
Yes this woofer can be used down-firing. The SA70 will be enough to drive the woofer to its limits so you won't benefit much from the extra power.

Does this speaker (SD270A-88) have an gasket on the front surface or do I need to provide my own? I will be mounting from the inside of the cabiner (non-removable grill)

Asked by: KK on the beach
I will answer my own question. I chatted with Parts Express support today (thanks Chris). There is a gasket on the rear mounting surface of the speaker (for front of cabinet mounting) To mount from the inside of the cabinet you need to provide your own gasket.

If I use a port that is 1-3/4" in diameter, and 4" long, what would be the best volume size for this subwoofer? Thanks.

Asked by: theodore
A 1.25 cubic foot enclosure will work fine with this port size, yielding a tuning frequency of 30 Hz.

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.
