If you move up to the top of the KEF line you'll hit the flagship Reference series, also recently redesigned to eliminate the pod tweeters. Shown here is a cutaway of the smallest Reference model, the Reference 201/2 ($5000/pair). The port for this model, which is smaller than its predecessor, fires out of the top rear of the cabinet. The duct is visible at the upper left, just to the rear of the white damping material.
