thanks Gonk, but my question is, should there be a certain db level that the subs should be, my thinking is fronts 80 db sub 80 db or should I just adjust the sub volume to what i like{I like good bottom end} be not boomy, but I want the subs to kind of match the fronts, I mean I went thru the response chart in the eq and the fronts are pretty good down to 40 hz.
