I really like Mesa's old Diesel cabs with the Electro Voice speakers. In my limited experience of playing bass cabinets (no stores here have nice bass gear) I haven't ever liked a cab more than a Mesa Diesel 115. Nothing else has had the cutting midrange and nice but non-harsh highs without being limited in the lows. However, these Diesel cabs are way too heavy. They are in the 70-80 pound range, I believe, which may have been reasonable for one speaker when these came out (not sure when that was) but these days there have been great strides in the weight of cabs. I want something that sounds similar (doesn't have to be exactly the same) and weighs less. I probably won't be able to find this for as cheap as Diesels go for these days, but something mroe like 40 or 50 lbs, and ideally 4ohm, would be great. Any ideas?
