Since I can't get a matching centre speaker to my Vienna Acoustics Malhers, I am thinking of trying the XTZ 99.25 as a centre speaker. I am not sure if it will tonally match my VAs but I have heard so many good things about the XTZ. Question is the placement of the speaker. The TV is sitting on the top of an open frame rack. Can I mount the speaker vertically under the TV inside the rack? Will it compromise the sound too much?
