I know that the X-Voce's were designed primarily as a center channel version of the X-Statik's for horizontally mounting. My question is could the X-Voce's also be used as front mains mounted vertically and using a subwoofer to extend the low end ? If so would the crossovers have to be modified? I don't remember anyone asking this question before. My guess is that the X-Statiks would probably be the better choice. Just curious.
