you may be right, but the missus will take my head or what's worse if i try to do a 6 sub 5.1 system... other than that, i prioritise music so my money would be better spend getting better front speakers b&w 802 diamond
so far i got lowpass with some eq'ind and hipass filters done, and oh my good my system never sounded that bad before
bass was good, mid end was thin and hollow and hi was "hurting" my ears. so turned of the hipass and let my front signal pass from dvd to amp to my front speakers.
so now im just using the low pass with equalizing, and my sonic "bliss" is back, now just with the lp at 70hz with a but48 slope it matches my front speakers down slope pretty good, but more work will have to be done before come close to a realy nice result.
