This sub was very surprising. I brought two along side with the box pro 206 speakers, and it puts out!!! The range of the sub is very good and you can push it.

there are a few down point to the subs.

1. no link outs to link it to other systems.

2. when at a loud volume are escapes from the back amp component which is noticeable up close.

3. don't be under the impression that it can handle a kick drum or large band. I use these mainly for acoustic sets in small bar and clubs.

other than these points this is a great sub. and I use it mainly for FOH monitors with my desk and it has done the job for the past few months.
