I have a small Ohm Walsh model in my basement and I've heard some of the larger models. The rendered spatial qualities of this design is fairly unique (a German mfr. has, at a higher cost, employed a similar concept for some years now). My critisms of earlier models are that the boxes were underdamped, and the previously used cone tweeters were too bright (to my ears, in my circumstances). They've since improved the boxes and switched to dome tweeters. Two changes which for me, are in fact improvements. I believe that the Ohms are still somewhat colored (are there any which are not?). But the illusion of space can be impressive. They are comparatively inefficient.
