Who has tried them? I know Quadzilla got a 4x10 and a 1x15, if I remember right, and he loved them. I was thinking of getting one of both of those and driving them with a Carvin R1000 head. How would this sound? I'm kind new to the whole head/cab thing, so I need help. I play a five string bass, so I need a lot of low end. I realze that the 4x10 isn't going to get really low, so I'll probably use the 15 alone for church and practice.
