I've tried a handful of cabs with the bass terror. The sp 210, the 410, they big 1x15 and currently I'm running an Ashdown classic 1x15 mini. Hands down in my opinion the orange 1x15 was the best cabinet in terms of volume and sheer mass of sound though it is one heavy heavy cab. The sp (isobaric) cabs were very interesting to me. Trying them out in the shop, I was very impressed by the sheer tone and volume coming from the 210...my only complaint (which is quite petty IMO) is the size of the cab..the thing is TINY! How it will handle at gig volume...I can't tell you but I can imagine my self finding it difficult to hear due to the cab being so low to the floor. To me, the Ashdown has the best balance from the 4 cabs. The Ashdown is small, light weight, has the volume of the two smaller orange cabs but had the same satisfying tone as the bigger orange. So IMO, the best bet for a cab to math the bass terror? A 1x15 with no tweeter..all IMO
