Im about to build GR AV1s, and A Tempest Sub (250w plate amp). I heard that the av1s may be lacking a little on the bottom end. My receiver has a fixed bass cutoff fq. of 90hz. , but i think it would be better in the tempest played up to about 150hz. Should I: A. Redirect bass to fronts, and hook up plate amp to fronts, then plate amp to front spkrs. B. All on (A.) but also hook it up to the LFE channel. C. Hook it only up to the LFE channel?
