A perfect fit under or next to our 1×12 or 2×10 combos and an excellent match for any of our heads. The Dr Z 2×10 cab is like getting 2 speaker cabs for the price of one. We offer a removable rear panel which enables closed back or open back operation. Standard 12″ speaker is the Celestion Vintage 30 (other Celestion speakers available on request, see your dealer). The 2×10 comes standard with our own Z 10″ speakers.
