Monoprice Bows 2 THX-Certified In-Wall Speakers in Monolith Line

Monoprice added THX-certified speakers to its Monolith in-wall speaker lineup, the company said Tuesday. The THX-275IW ($349), with one 6.5-inch woofer, a 50mm silk dome midrange driver and a 25mm silk dome tweeter, is THX Certified Select; the THX-465IW ($699), certified THX Ultra, has four 6.5-inch woofers for larger rooms. The architectural speakers meet "strict THX performance and listening standards," the company said. All Monolith THX Certified in-wall and in-room speakers use the same drivers and crossover components, allowing speakers to be mixed and matched in any room, the company said.
