They tested a bunch of coaxial = speakers (from Tannoy, KS Digital, and KEF) and favored the KEF e301 and = LS50, that is, the same speakers as Bob Rao suggested, especially = because these speakers have a particularly stable directivity and = frequency response at crossover frequencies between the exterior = low-/mid-frequency driver and the interior high-frequency driver. If you = have any detailed questions regarding these speakers you could just = contact them (contact@xxxxxxxx <mailto:contact@xxxxxxxx>).
