Thanks for all the kind words guys. But of course, I can't take credit. Everything in the house (except for the Axiom's) is my wifes doing. My job is to show up, don't ask questions, load the van, don't ask questions, then go back in and pay. Oh yeah, and don't ask questions.
Peter: Really glad I went with the 600. The immediate room is 6800 cu ft but, (depending on what you count in) is open to ~ 12,000 to 15,000 cu ft. Even with that volume, it pressurizes things quite nicely. But the room nodes/modes have been wicked. I've tried that thing in a number of locations, and that left corner is the best peak/null and wife/marriage compromise.
John: The sofa/couch is exactly 3ft off the back wall. The bottom of the 8's are 74" off the floor, and they are about 15ft apart. Because of the openess and lack of reflective boundarys, by ear, I've got them goosed by about 2 to 3 Db.
