My room is about 20 x 40 but the 40 flows into an open area in back. As to speaker placement, I have Zero Flexability. They are about 7 ft apart and my theater seats including the center seat is about 11 ft away from speaker fronts.
As to which to upgrade to..... I would love to hear the whispers but I know how physically huge they are. They would look insane in my theater room. The aeris is only about 4 inches taller than what I have now and about the same width, so that would work. Are you running the wavelet pre amp with those Whispers because that is what I also need to consider in any future plans..... yes? I will read your reviews
