My room... I have bay windows at the rear, left and right windows on angles. The right wall has built-in shelves. LPs fill up most of the space. The left wall, no shelves. 9' ceiling, 16' L x 12' W... BUT behind my sofa (listening position) I have another open 14'x12' room, so I don't get reflections from the source. Have a large area rug on the floor. It's a fairly dead room.
The speakers are about 1.5' from the back wall. Each about 1.5' from side walls... although because of the shelves on the right side, the "cove" makes it about 2.5'.
I've spent about 10 hours or more finding the right position and still not there. I have a weird room. But definitely try toeing them in more than you might normally. That I have found to be a constant for the best imaging.
At times, I've probably got them 90% "there" and when it's right (or close to it it) it's crazy good. Then I screw it up by trying another position.
Lastly, they require a 4 Ohm load, so hopefully your amp has that output option. They need power... I'm cranking up the volume knob on my pre another 20% than I needed to on my Focal speakers.
Please post your thoughts when you get them.
