I have one for the Trace Cab experts: I have an 1153, and have been using it with a 1048, running 'em with a MK IV AH250.
I really would like to have 2x 15s, and I wonder what the 1153 with a 1518 would be like as a stack? Would the two cabs be poorly tuned if run together?

Would I get some phase or frequency cancellation?

Or would it be stupendous?...
Discuss?...
