The center-channel companion to the Micca RB42’s, these speakers along with a subwoofer will round out a nice home theater setup in small-to-medium-sized rooms. Notably, the RB42-C is also more efficient than the regular RB42, so you can drive it louder with less power.

This is the smallest floorstanding model in MartinLogan's Motion i lineup. In addition to the folded tweeter, these speakers use two 5.5” drivers, one handling midrange-bass frequencies, and the lower one dedicated to bass alone. Wide, detailed soundstage, but probably best paired with a subwoofer for home theater use.
