Clearly, another 212 would be the answer, but seeing as how i wont ever see the maximum volume that 2 212 cabs could produce, could I save some coin by grabbing a Neo 112 or 115 to stack on the 212? There are extensive threads on doing this, and many experts (Norm Stockton and Tom Bowlus) like the stack even if you dont get equal power running to the 112/115. Im just curious as to how much extra volume I could get with an additional cab, keep in mind i am doing this for the sound dispersion and not necessarily the extra power, as putting a cab up higher will warrant less volume anyway being closer to my ears and off the ground. It would also be nice to have a small one speaker cab for jazz dinner/restaurant style gigs. Anybody hit the limit on this setup, or can I run this and not worry about the smaller cab?
