I have a PSW10 as referenced above and it is very good, as equipment goes I have never once thought of upgrading this sub. My room is 12' X 18' and this sub easily puts out as much or as little low end as I want or need, just thought I'd post this in case anyone is on the fence and needs input. FWIW...
