Saw the below image over in the MB200 thread and it's making me want more information about the powered enclosures! The image is vague, offering only the existence of such enclosures and a back panel picture showing an XLR in and XLR out. Presumably, they can be used as extension cabinets for the MB series combo amps. That said, with an XLR input, and the fact that the MB combos only have an XLR "direct out" output, I am curious as to the usefulness of such a powered cabinet off of a DI or similar. Could you run one of these off of a DI? Does anything else like this exist? (Google didn't seem to think so) Of course, information is not yet up on the GK website.
