I have spent some time checking out amp manufacturer's websites and doing some searching in the TB archives and have come to the conclusion that buying a complete (quality) rig that is powerful enough to play with a band is a bit out of my budget at this time. My thought now is to buy the head, and the components for the speaker cab and build the cab myself. I am a cabinetmaker by profession, (but don't know much about the science of speaker cabinet design) so building the cab is no problem as long as I have a drawing to work from. I would appreciate any suggestions for books, websites, etc., where I might find general info on cab design, and specific plans to work from. As with a lot of players, I'm looking for the biggest sound from the smallest possible package. (I am really intrigued by the Schroeder 21012--is it really comparable to an 18"?) I am also looking for sources to purchase speakers (and hardware) as well as reviews, comparisons and recommendations. Thanks.
