The room I put my newer Walsh speakers in is a larger L shaped room. They replaced planar and conventional more directional box speakers in there neither of which worked particularly well. But the Walsh speakers tend to just place the music naturally into whatever room they happen to be in. A very unique attribute that many might consider.
I find a main main key to good sound with OHM Walshes in particular in any particular room is to address floor interactions when needed, especially with the bottom firing ports on many Walsh models. Isolation platforms like Auralex Subdudes I use with my OHMS when on suspended plywood floors solve the problem.
