I just got this but, did a noobe thing and got a 4ohm not realizing I could not add another cab to it with my head. I am am asking 275. shipped to lower 48 which is what I am in it. Low ballers and bottom feeders welcome I'll smile and wave. The speakers are about 70.00 each I do not have othe original speakers. 400 watt total Here is the description from the ebay auction AWARD WINNING CAB WITH UPGRADED SPEAKERS The Avatar B210 bass cab received the EDITORS BEST BUY AWARD in the July, 2004 issue of Bass Player Magazine. The testers were "floored by its gutsy tone and room-filling volume". This was their conclusion and the final paragraph of the review: "Overall the B210 is a pleasant surprise. For its small footprint and small price tag, its impressively loud and balanced. For most gigs and practice settings, you probably wont find a more satisfying 2x10 cabinet anywhere near it in terms of price and performance. This little dude rocks." The reviewers said if the B210 lacks anywhere, its in the ultra-low range. So, instead of the stock Delta 10's (that have a useable frequency range of 65Hz to 3.5kHz and Xmax i.e. extended cone travel, of 1.6mm), I loaded the cab with two Eminence Legend BP102's (that have a useable frequency response of 40Hz to 3.5kHz and an Xmax of 6.2 mm, nearly four times the Xmax of the Delta 10's). The result is an award winning cab that has a much bigger, fatter and tighter bottom end, and a cab that goes ultra-low.
