You guys crack me up. Is there a place where I can get educated on every important aspect of a cabinet besides the speakers. I know that the wood and the size and how well it's sealed make a difference, but what difference or how much I honestly have no clue. I just have 2 4 12 cabs that sound too dark for my taste, a bit muddy, and thought that might be a cheaper alternative to buying a new cab. I just don't want to spend less money and not get a good sound.
