Good so far.

I just got an email that said ive had this sub for 6 months. Sounds about right i guess. It sounds great. I mounted it into a sony slim box and it seems to hit with a deeper bass than the sony. Doesn't buzz as much either, nice and clean bass.

good subwoofer

everyone told me shallow mount sub was not the way to go, but that was all the space I was allowed. After installing the sws, no one believed me that it was actually a shallow mount. Nice job earthquake.
