I stumbeled across as graph somewhere here that helped you pick out the cab size for different woofs. This was an altec graph with a list of woofs that you could use. Now that I need to come up with a dimension I can't find the graph. Can anyone point me in the right direction?

Hello, I just recently did a design/build for a pair of 515B's and used the 612 design and beefed it up a little to get the CF I wanted. The chart calls for 12CF I wound up with 11.38CF minus the crossover, and bracing probably netting somewhere in the neighborhood of 11.0CF and they sound nothing short of Amazing! Warm and concise. What horn and crossover are you planning on?
