It's looks like my 20 year old super cube (the 100 watt 15) is going to break me before it breaks. I would like to retire it and get a lighter weight (approx 40 lbs or less) cab for my jazz gigs. Most of these involve unmiked drums and horns, electric or acoustic piano. Occasionally I might use it as a stage monitor when I can go direct into the mains. The caveat is that I would be powering it with my swr studio 220 which only puts out 140 watts at 8 ohms (220 into 4). So a 4 ohm cab or a sensitive 8 ohm seems to be in order. I will playing a 4 string through it. Looking through the archives of various forums I've read good things about the Bergentino 12, Aguilar 12, EA 10, IA contra and Bag End 15. I've even had a recommendation for the nemesis 2X10 cab. I know that the only way to do this right is tote my bass and amp around and play through the cabs. Unfortunately, out of several choices I might have, only the Berg and the Contra are available for testing locally. If anyone has a/b'ed these cabs or any thoughts or recommendations I would be appreciate it.
