I’ve had my X3s for four months and have settled on a setup I’m really happy with. I had much more toe-in in the beginning but they are much flatter to the front wall now- 16 degrees. Measured to the center of the 12 inch driver the X3s are 8 feet apart and 11 feet to my listening position. That points them outboard of my shoulders. This creates a very broad soundstage with a well-developed center. Outboard of each speaker are two GIK free-standing panels dealing with first reflections. No treatment behind the X3s. Lots of treatment on the ceiling and back wall. Large area rug on the floor. Amazing speakers as you know. No fatigue at all. Nice work Mr. Shaw.
