Ok, I have an idea of combining 4 12's and 4 10's. 12's seem to be capable of pushing more air and provide for lower frequencies with less cab *fart*. The 10's will provide the punch and highs willst moving air. The cab should be fully bi-ampable and feed the lows to the 12's and highs to the 10's. The cab would look something to this nature: I was thinking of using Eminence DELTALITE® 2510 for the 10's and Eminence Swamp Thing Patriot 12's. What are your thoughts? Has it been done before? Would the cab be to big? Am I just a dufus and making pointless threads? PS: Sorry for crude ms-paint skills :/.
