Atrend 15" Single Vented

I'm using this in my stereo system in the living room. I'm using a Planet Audio driver, and a 950W RMS Yorkville amp. I cross it over at 16Hz (slope means it works up to ~40Hz) Plug the port with a pool noodle to eliminate "chugging" though. I will never run this at full power, but it works much better than a crappy active sub that won't go down past 25Hz.

Arrived early and in perfect condition. I installed a DS18 15" and so far so good. Got 2 American Bass DX15's now and they pound.

Good solid box just a bit smelly so take it out and air it for a few days before installing in vehicle.

This is a reallly good box for the price, can't go wrong. As another reviewer said, the description is a little misleading as part of the construction is 3/4" mdf (as advertised) and part is only 1/2" mdf. I sprayed the interior with plastidip to sort of thicken it up and prevent vibration, although I'm not sure if that was necessary, it does seem well built and glued together. Porting frequency seems a tad high (see UPDATE below), maybe 45 or 50hz or even higher? ...but it's easy to lower the porting frequency with a wadded up old tshirt or a pool noodle as another reviewer suggested. In an automotive application it might be low enough, for home theater or dnb or hiphop shows maybe experiment with a pool noodle in the port *grin*. Overall, this is a fantastic box, well built, pretty compact, a real steal for under $80 shipped. ~~~ Note you will need a drill bit for speaker holes, some screws for mounting, some wire to connect your sub to the terminal. UPDATE: Confirmed the porting frequency is much too high, added it at a show to a KV2 dual 15 (one of the best sub setups) and this was literally canceling out the lowest notes of the KV2. We finally shut off this sub. BUT, that is an easy fix, partially obstruct the port with something like a pool noodle OR if you are near a wall place this sub an inch or way from the wall facing the wall. This will effectively lower the porting frequency and it won't cancel out the 35 hertz notes from your other speakers. Still great for the money! editagain: In my pic I'm using "Allstar - ALL14100 Black 3' Roll Bar Padding" to mostly obstruct the ports and the porting frequency after doing that is about 31 hertz. MMM mmmmmm (I'm guessing it was 45 or 50 hz before that, much much too high)
