I've recently purchased Trace Elliot AH350X. It came with a 4X10 cab. The amp has a two outputs. One channel is full-range and the other is 150W for the high range with everything below 250Hz rolled-off. What I'd like to know is if there are any small-ish, off-the-shelf cabs that would lend themselves to being essentially a midrange cab. They would have to be no less than 8 ohms and be able to handle at least the 150W. The smaller, the better. I only play flatwound strings on all my basses so I don't make much noise above 5 or 6 KHz so a tweeter is not really essential. I would love something like a couple of 6.5" speakers in a low-profile box but I think I'm getting into custom speaker box territory. Any suggestions?
