I'm about to start a build of the ZRT in the MD20 to upgrade from a pair of B&W 805s. I unfortunately don't have room for either of the floor-standing variations.
Zaph's instructions show the 2-way as a sealed enclosure, nice from a build simplicity point. Would there however be any benefit (or detriment) to adding a port? If so, any thoughts on front or back, position, diameter, cabinet damping approach?
