Hey everyone, So I have this vintage rickenbacker cabinet that measures 43"Tall x 33"Wide x 18" Deep... that should make it 14.78 cubic feet (correct me if I'm wrong)? I'm looking at building a new baffle for the cabinet and loading some new speakers into it. My goal is to have (probably) 4 15" speakers in it, and make it a mono/stereo cabinet, so that I can run 2 amps into 2 speakers each if I'd like. The amps I'll want to use with the cabinet are a peavey classic 400, Ampeg V9, traynor YBA200, and Rickenbacker B115 (120W tube) so the speakers I'm looking for need to handle a ton of volume, and I won't be using a super hifi clean amp with them, so I need to be able to run some distortion into them and have them not blow up. Ideally, I'd love 4 JBL E-140's, and I'd call it a day.. but I have a few really heavy cabs already (a couple 2x15's and another 4x15) and I'm not sure I want a 3rd.... I'd rather something a little lighter, and a little more usable. Question is: What 15" speakers will be able to handle the thunder (2 speakers need to handle a Peavey Classic 400 with ease) that don't weight a ton (something neodynium?), and will have that vintage, dirty midrange, while still tons of bottom end? I don't mind any suggestions you might have, even speaker configuration (if you think a bunch of 12's would work better). thanks!!
