D-Rowe, thanx that makes alot of sense, I also have bp2006's and a procenter 200 in the center. I don't have rears yet I still haven't decided which to go with yet. Any ideas? Also, For some reason I can't calibrate my 2006,s past 71 or 72db. I do everything right including setting everything on flat and turning my volume to 0 with no source playing.My center seems to be louder then my mains. I made sure all the woofers and tweeters are working front and back, I even hooked up some old polk audio towers (R-50's with a sensetivity of about 87) and they seem to calibrate louder then my deftechs. Like I said I can't go past 71 on the deftechs but I can go 80or 85 on old polks with a lower impendence.What do you think? thanx. D-rowe, just for your info I have the 755 power amp.
