Hi, to be honest I do think they make a difference. Because of how my room is shaped left speaker is nearer the side wall than the right speaker. As a result, sound from left speaker appeared to me as stronger and stereo stage was moved to the left which was very annoying. Since I installed acoustic panels on side walls and the rear wall the problem has disappeared and the listening experience is much better. Also, since they look great aesthetically WAF was not an issue either.looks great, do you think they make a difference?
