I am about to make an expensive change to my rig and I could use some advice. I have an Ampeg b4r bridged mono to a svt 6/10 and I don't d-tune but I go down on the b alot and I play loud. I don't think it's my Warwick corv. jazzman, I think the cab can't handle the low end. The sound is bad it farts and bottoms out with the pre less than half and the main less than half. It is bad enough that I can't stand it anymore! I am convinced I need a better built cab with cast drivers with a higher wattage rating! I am thinking the ampeg pro 4/10 hlf or the Eden xlr 4/10 or swr 6/10. I want the loudest cleanest low end that WONT break up or distort if I punch my B! What would you guys suggest. I don't want an 8/10 it's too big and 2 4/10 would be a little expensive. Would like one cab that can handle my beast of a head. Thank's for any good advice!!!!!!!!!!!!!!!
