Hi guys, I've decided to build a cabinet (1x12, 1x10). So I've chosen speakers. I think it will be eminence kappa pro 12 and kappa pro 10 + eminence super tweeter APT:80. I'll be grateful for some opinions and suggestions. Should I build one cabinet 1012 or two cabinets - one 10 and other one 12. Oh, and I play 5-string bass with low-B. What box dimensions are necessery?
