bass problem fixed

absolutely none

the problem with weak bass is solved with a subwoofer...all the low ranges are pumped through the sub pre-out, not the mains. i have this hooked up to a KLH-9006 H.T. speaker package with a sub and it sounds phenomenal...they obviously designed this thing to be used with a sub. Sounds better than my old setup, and the speakers were only 120 (5 speakers plus 100 watt sub, not bad). A great buy, would recommend! KLH speakers by the way are VASTLY under-rated!
