I don't know whether I can "certify" that 6.5ft gives good integration. To be honest, I don't know and haven't been taught to appreciate what it means when people said they can hear different drivers. I probably need to ask a pro to educate me a little. But the Salk HT3, despite only 6.5ft from my ears, disappear completely in the room, sometimes I still couldn't help staring at these speakers and asked myself - where's the sound from the speakers, my whole body is on the stage, but I don't hear any speakers, I hear guitarist 3 ft 30degree to my right, drummer 4ft 20degree to my right, singer, 2ft right in front of me, piano all over the place, bass guitar 4 ft 45 degree to my left.....etc... does that means that I have good integration? Or "integration" has nothing to do with speaker disappearing?
