I am new to this site and my last thread got no responses so I thought I would try a different title. I am trying to create a home theater surround room for both movies and music. I currently have the old Klipsch KG4.2 floors. I also have 2 Klipsch surrounds. My plan is to add a center and a sub. I have to decide between finishing it all out with Klipsch or combining the speakers I own with a DefTech center and sub, one of which I got as a gift. Is there a problem mixing these two lines, would it be better to stick with all Klipsch, or should I try something all together different?
