My original plans were to use two VP100 in the rears, with the QS8's on the sides..
I had a concern about allowing for the M22's ports, etc.. The VP series can be more flexable with placement, and the speaker locations in the back needed to be up high and against the walls.. Joe, at Axiom, uses VP150's for his two rears and is quite happy with the set up..
My final version was four Q's, but I wonder sometimes... If we oooonly had enought 'free' funds laying around, oh the possibilities..

LFE ! The rest is just details..
