need some help with speaker placement in this cabinet. I was thinking of placing the left & right speaker either in the cabinet space below the glass since this cabinet came with doors that replace with speaker screens or placing them in the gapping space on the sides below the tv. As for the center channel speaker, I have no idea where to place it because it is too big to fit on top of the tv. The speakers are NHT bookshelfs and a NHT center and a 12inch NHT sub. Any ideas?
