I've not put much thought into room treatment yet, I'll wait until I hook everything up and have a listen. The room has asymmetrical walls along either side, this coupled with the furniture and a couple of areas rugs should sufficiently soften it up. The flooring is actually quite 'soft' as it's laminate, not hardwood and the delta subfloor, and relatively thick underpad should help absorb some of the highs.
I picked up my screen last night; I'm looking forward to seeing the final results of the built-in screen frame.
