I'd love to see a 2 X 12 Cabinet with Kemper Kones offering a removable back panel to be able to make it a true open or a closed back cab. I've read in the forum that the Kone speakers can support a bass, but not in the current Kemper cabs which rattle from the extended lows. I would like to see a new cab reinforced enough to be able to use it with a bass as well as guitar. It would be nice if it also had a removable port in the front for even more extended bass output when needed. Options for stereo power amp built in and an un-powered version. Heavy duty metal corners to make it road worthy.
I have played through many of the old Roland JC120 amps and even though the the stereo field was not spread across the room, it still gave an awesome stereo sound which was worlds bigger and better than mono.
