@Will my panels are 69″ between the insides and my ears at the apex of the triangle are about 40″ from the plane between the insides, so much flatter than an equilateral triangle. I’d experienced a strange sonic phenomenon at Mike B’s when I walked through the panel plane–very disorienting. This is not like that, perhaps because of the diffusion of my record shelves? Regardless it’s nice to have stereo when working at my computer. Kinda like the Martin Logan mini desk speakers only MAXI sized! 😉
