Im feeling confused about the best cabinet design for me. I play primarily Chicago style blues in a club setting. I have a Fender Jazz bass and an SWR Bass 350. Im presently using a Peavey 1820 cabinet. The tone is decent but the volume is not really there so Im planning to sell it. Plus its 120lbs. and the size of small refrigerator! Ive seen people refer to Bill Fitzmaurices's Omni Pro 12 on the Forum but from the literature on his site, it appears to be a full range cabinet. Why would I care about frequencies above 5KHz? Could I just delete the tweeter? Whats difference between the Omni series and the DR series? Would either cabinet be appropriate for what I'm trying to do? I'm also looking at the Avatar B210 and B212 as possibilities. What I am after is really good low end to get the blues growl and an easier-to-haul cabinet.
