I have built a set of Dayton 8's from speakerbuilder.net I would like to build a matching center channel when I go front projection and was wondering if there are changes required to the crossover to place it horizontally? I have emailed Wayne J. at speakerbuilder.net and haven't heard anything. I am also going to email Dave Tenney since I believe this was his idea and wayne did the crossover modeling for him. Yes I realize we are talking about a very large center channel I may modify the box size and use pr's instead of ports I dont know yet. Main concern now is the crossover.
