Their lightweight cabs are very low-end shy and have an almost 'Peavey-esque' upper midrange emphasis, but centered at a higher frequency and with a wider bandwidth. I have three of the VERY heavy HD212 cabs they made for Ernie Ball, and they're downright awesome. I've played their lightweight 1x12, 1x15, 2x10 and 8x10 and every one of them had the same basic voice.
