I think I will just be another voice in the chorus, I have five speakers, all Boston Acoustics, in my system. You can't beat having that kind of blend. I did read in Get Better Sound that the tweeters of the front speakers should be as matched in height as possible. When I inverted my L/R speakers the imaging really improved. Also, move any coffee tables out of the way, they just block and reflect the sound.
how much did you spend on rear surround speakers?
I thought i would share my experience setting up my home theater speaker system. I had Dali Helicon MkII for my fronts and Dali Helicon center. my side surrounds were an old M&K from one of their early surround systems. I replaced the M&K side surrounds with Dali Helicon C200 and was very happy with the sound. I moved the M&Ks to a rear surround position for my 7.1 system. However, when i found a pair of Dali W200 on Audiogon i bought them. After setting up with Audessey from my Marantz AV8801 processor, i was extremely pleased with the improvement in sound. I was very hesitant to spend much on side and rear surrounds, but in my experience, the extra dollars to have matching voices from the Dali helicon line actuallly made a difference i could hear.
