I've always liked the fact there is a gap between bottom front panel and keybed on (most) verticals so the cabinet is not presumed air-tight. Customers have asked about this, and I've always suggested (perhaps erroneously) that the DC needs to interact with room air to be effective. That is, the movement of air caused by heating encourages an ongoing exchange with air in the room, but not on par with a draft. The (3-4) 1" plate-stud holes in a vertical soundboard allow my vivid imagination to picture air exchange between front and back in the same manner. The backcover just removes draft air from the equation. Mind you that's just my imagination, and right now the cloud passing by my office window looks like a 65 foot-long Fazioli,..! :>) Mark Cramer, Brandon University
