TWO THUMBS UP!!! This cab sounds amazing, a-maz-ing. The sound is so good and puts out good volume with GK400RB. I bought used off a fellow TBer and he had it for about a year and it is still in great shape and sounds great. I think i would use the B115 over the Avatar 4x10 if i only needed one of them. I can't describe how happy I am with this purchase. And i got it for such a great deal ($188 after shipping). And to think that i almost didn't buy it. If anyone is thinking about getting this cab...don't think twice about it. It is def. worth it. When i was first reading about the cab, i thought it wouldn't be that good since it had no tweeter but damn this thing doesn't need one. It sounds perfect. I can't wait to play through it with the band.
