Simple. Valuable. Capable. For those systems that do not require extensive bass reinforcement from the front-end, we introduce the simple and effective 6X1. A true two-way design, the M6X1 incorporates a single 1-inch ferrofluid-cooled tweeter, along with a single 6.5-inch woofer. A pair of simple switches located on the front baffle adjust the crossover, to enhance performance based on the installation. The result is a compact and cost effective in-wall speaker that is dynamic in application, and yet still delivers the higher audio quality associated with the PSB name.
