I have an opportunity to use a matching powered tower as my center channel speaker. Is this a good idea? It is the same tower I have as my left and right front channel speakers. All three towers fit perfectly under my screen. But is it a good idea to use a full range tower as a center? They are Phase Tech 11.5 towers consisting of a 1" soft dome tweet, a 6 inch titanium mid driver and a 10" woofer. If I do use the tower as my center, should I run it full range or use the woofer as my sub?(tower has a separate line input to run the 10" woofer from my amp and leave the tweeter and mid running full). Thanks for any help guys.
