I plan to follow Wayne´s recommendation and choose a pair of Delta 15 drivers. I´d love some help to get the dimensions for a pialigned cabinet (with driver placement on the baffles, etc which the little program does not help me with) for these drivers. Also Wayne, does the Delta 15 integrate well with the Alpha 8 or should I choose the Alpha 15? Also, how big is the difference between the Delta 12LF and Delta 15 in deep-bass capabilities?
