why do you want to mix speaker brands? if i was buying a new system from scratch, I WOULD NEVER MIX BRANDS!!!!!!!!!!! speakers not including subwoofers that is. people are funny, i dont know what makes them think that mixing two totally different brands makes good sense. only if they are the same can you mix, and as we all know they never will be. if you had high performance tires on your vehicle would you throw any old tire in place of one? no, because your car would handle like crap. not to mention that in speakers the difference is greater between brands, so that would be like putting on a sorry, wrong size, wrong width, wrong speed rating, and wrong traction tire on in place of one that is part of the pair of 4. but hey, what do i know?
