I'm looking at a used Gallien-Krueger MB200 mini amp head with a custom-made, lightweight 1x12 cabinet with an Eminence speaker, offered locally. The cabinet was presumably made with the GK head in mind, and supposedly weighs about 22 lbs. It doesn't appear to be ported, from the pictures I've seen. Besides trying this out to see how it all sounds, what questions should I be asking about the cabinet, to determine whether it was intelligently designed for this application? It's a bit of a drive to go look at it, so any problems I can pinpoint over the phone will potentially save me a lot of time and gas.
