PJB says that four of the 5" drivers approximate to to a normal 10" driver with a 4" voice coil, and I was told by them that the 6B is equivalent to a 1x12, but with a really big voice coil! Also, the cabs are a decent size - about the size of a 2x10 but much deeper - so the amount of energy and volume of air being moved is really very good.
The amp is a substantial 29lb/14kg. It's certainly no micro head, but it's perfectly managable and has a reassursing solidity about it.

The build quality is superlative, and that was one of the things that attracted me to it. PJB build nearly everything in house, right down to the bolts, and their QC is first class!
