I've got these 24- 87 cent PE 4" speaks (269-570)that are on all the boards. Also have the JBL M115 15" Badboys that were in the 3677s cabinets. I was thinking of a hybrid woofer array with just a 6" wide board sticking up from the back of the 18" or so square box that houses the woof.
Do the array speaks need a sealed enclosure? Open baffle would be okay? Could the woofer be mounted on an open baffle, too. Like a 24" wide by 72" tall piece of plywood with all 13 drivers on it? Or maybe a pyrimidal shape so the 4" guys have less baffle around them?
And wassup with the crossover numbers I'm getting on the Excel worksheet page? 100's of mH's and uF's with 8 ohm crosses at 125 Hz?
Or mebbe I don't need a crossover? Or being hopeless at Math I just don't get it?....... "Roman's plural,Hmmmm?
