I invested in some speakers and need to build cabs for them. How do I go about designing a box for them that is the correct size etc? Any good web sites on the subject? Or how about a mentor? bgavin? Joris? Mikeyd? I 've got 4 Eminence Pro Twelves. They have 80 oz magnets in them. I want to pair them up to use on each side of the stage when we play out. I would like to design them to tip back monitor style or flat/stack. Should I throw in tweeters? Ported? I have all the specs and parameters etc but don't know how to apply them to building a cabinet. HELP!!!!!
