OK guys, I need some help picking speakers to put into a Peav 2x15 cab I bought yesterday. The cabinet itself is in great shape, but the original speakers had already been replaced, one with an Eminence 15FABABB 67-7112 (I don't know what this is, but I'm thinking it's something I won't want to keep, and the other was just junk. So I went searching here and after reading a few posts, went to Parts Express. I found some possibles, like Kappa 15A's and a couple Peaveys. This cabinet is actually two 1x15's stacked, and by my calculation the volume of each is about 3.4 cuft including the port. The electronic connection is your basic parallel hookup, but it would not be any trouble to run another jack into the bottom and electrically separate the speakers if that would be advantageous. Soundwise, I'm open, just not bright. I can go either 8 or 4 ohm. So, you guys know a lot more about this stuff than I do - what can I do to make the most out of this cab, with moderate $ and moderate effort?
