I have the dimensions published by Ampeg for vintage 8x10: http://i.imgur.com/6274M.jpg I want to build a 2x10 that will have the classic sound. I thought perhaps start by building a cab 1/4 size of the Ampeg enclosure. I need the interior specs. I assume the published specs are exterior; also, that they are using 3/4 ply. I wonder about the hight, does it include the feet? Anyone with the interior dimensions of an old cab or educated guesses, build experience? I have a couple of CTS 1975 speakers, I'd like to use. appreciate any help, fnord!
