I am considering getting one of either of these cabs. I have an Ampeg 410 that I love, but the thing weighs 122 lbs. Too much to drag to practice. Here's where the Avatar comes in. I could get one of the single 15 cabs with no tweeter and use it for practice, and pair it up with the Ampeg for larger gigs. The CB115 doesn't go as deep as the B115, but it is lighter, smaller and less expensive. Which one would you recommend to match up with the Ampeg BXT-410?
