I'm back on my "build a bass rig" project. Im looking for feedback on some ideas before I just start buying random gear. FWIW, I do the 4-string, blues/classic rock, mid-sized club thing, and not always with fantastic PA support. Right now I'm still picking out an amp, but will likely end up with a big-ish dual power amp head, around 350-400 watts/channel (Ampeg B4R or SVT 4 Pro if I decide to spring for the bucks, a Hartke 7000 or Carvin R1000 if I'm feeling frugal). My current speakers are: a 4-ohm Peavey 210TVX and an 8-ohm Avatar compact CB112. I'm currently driving them with an ancient Acoustic 370, which sounds like crap with either/both cabs. I think that thing is voiced more towards a pair of folded horn 18 or multiple 15 speakers. Its days are numbered! Any collectors out there? Things are fine at low volumes, but I sound like so much farting at band practice volumes. And volume-wise, we take things relatively easy at practice, being old farts ourselves (yuck, yuck). My current theory: Get the new amp, run one channel for the 210's, and the other for a PAIR of CB112's. I already own one CB112 - I would need to order another. This set-up should move air with the 12's, provide punch with the 10's, and have enough power and headroom to keep everything clean. Amps are running at 4 ohms, so they should be happy. And I kind of like the small, modular, mix n match speaker idea. May not LOOK as cool as an SVT 810, but My biggest concern: The Peavey 210TVX MAY not be up to the task. It is only rated to 175 rms/350 peak watts. The Eminence Deltas that Avatar uses in their cabs handle much more power. If the Peavey speakers die, I was thinking about replacing them with some Deltas. I may even switch them out upfront. That would be a prophylactic speaker switch am I allowed to say that in this forum? Soooo What do you TalkBass folks think about this scheme? Any advantage/disadvantage of a compact Avatar CB115 instead of the second CB112? Am I missing anything obvious? Thanks for all your help - Bob "Frugal gear selection = more gear"
