So I will be rebuilding my open baffle speaker wooden fronts because it's time to use some beautiful local wood I recently saw at my mill. I will start this by saying that I a very happy with the sound I am getting with my current set-up, but as always I am looking for improvements and love to tinker. The wooden fronts I am rebuilding are 15" x 38" and will be made of local cherry and black walnut. For my full range I am using Wild Burro Betsy's and each side has 2 x 10" Goldwood GW-410D for woofers and are powered by a Yung SD200 200W. I will be installing Eminence APT-80 tweeters pointed at the ceiling. My questions are, could/would I benefit from replacing one of the 10" with 12"? Also what about the width of the wooden fronts? Would these benefit from maybe making them 16" or 17" wide? Wider?
Last question, my power amp is the Audiosource AMP 102 and has an A & B speaker option and both can be used at the same time. I plan on using Blue Jean Cables Canare 4S11 Star Quad Cable and using two conductors for the Betsy's and 2 for the Eminence, one from A and one from B. Is this the correct configuration for this set-up?
Thanks for your help!
