[QUOTE="Timber_MG, post: 496541, member: 18"] The rear tapered transmission line is certainly not a B&W first, just the visual design of it probably is. Foldings work but only over a limited bandwidth, though if it's damped continuously one could probably get away with a lot more than with a horn for example. Tuned transmission lines like this can be used to modulate the impedance of the driver, but acoustically the impact is much smaller than that of a front horn. That said, many under damped boxes add some lively character to the sound but do this at the cost of a natural midrange and add an oddly resonant plate type effect to the sound. This is at the opposite end of something like a Harberth. [/QUOTE]
