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.

Similar to the MartinLogan 50XTi, but slightly smaller, with 5.25” woofers, this center channel still has large-speaker presence, with a respectable low end response of 65Hz. Inclusion of the Folded Motion AMT-style tweeter gives this speaker clarity and can handle louder volume levels with little evidence of compression.
