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.

A midsized rear-ported bookshelf, featuring a 5.25” low-frequency transducer and a folded motion high frequency transducer, which MartinLogan claims replicates much of the performance of their high-end elecrostatic speakers. May need to be paired with a subwoofer if sub-60Hz bass is a priority.
