I have inherited a set of Altec A7 speakers and thier sound is magnificent. My theater room is large enough for these big boxes but, will I run into trouble trying to find rear speakers that will compliment them? I am afraid that the cost of matching the rest of the system to them may may outweigh the benefit of the A7 VOTT speakers. My Real Question; Are they worth the trouble or should I sell them and use more modern and more modestly priced speakers.
