there is no way that the solobaric is better then the w7. the w7 is the standard of all subwoofers since it has come out, true it might cost more but you only need one. the w7's are so powerful i have not heard of a peak power handling spec on them yet. they have taken over 2000 watts of power and have not blown. i was up at a cartunes and asked one of the salesmen about them and they said that the company even tried hooking up home stereo amps to them and they still havent blown.
