Could someone please give me some help in choosing speaker cabs. The situation is that I play in a band that does mainly pop/rock/party type numbers. Our guitarist is the usual Les Paul freak who has to have the amp turned up to 11 to get the sound he likes with the result that eveyone else has to wind up to be heard. At the present time my gear consists of an "Acoustic" 370 amp which I play through a Marshall 4x12, 16ohm impedance cab (yes, I know it's madness, but it was cheap), and I'm looking to replace the enclosures with something like a 4x10 and a 1x15. What I'm really looking for is something that is not only reasonably loud, but can be felt as well as heard. At present, this beautiful amp is just too much for the existing speaker set-up and the bottom end just doesn't exist. Any suggestions would be gratefully considered. Ta. D.V.
