As others have remarked, it's nice to have a good-sized room dedicated, or seemingly so by the pics, to your setup. I received my own X5s not quite two weeks ago (I was too impatient to have them broken in at Spatial, so I'm starting from scratch) and, like yours, mine seem to improve almost daily. So, either I or the speakers seem to be breaking in nicely. I'm curious how you decided on the treatment you have and if you bothered with any on the side or rear walls. I have no treatment whatsoever as yet, and I still, after less than two weeks, get a deep, clear soundstage that extends well beyond the width and height of the speakers. I imagine having the right treatment would only improve on this. I'm waiting until the speakers break in something close to completely before adding treatment, so I have a better idea of what to address, if anything, but I'd love to know how your panels and diffuser affected the sound of yours. Thanks in advance, and congratulations.
