Monoprice Adds THX Certified In-Wall Speakers to Monolith Line

Two models added to the line one with a single high-excursion 6.5-inch woofer and a 3-way model with four high-excursion 6.5-inch woofers.

Monolith, the high-end audio brand from Monoprice, has announced the addition of two new in-wall home theater speaker solutions that have been THX Certified to ensure listeners experience sound that is incredibly dynamic, detailed and immersive.

Monolith THX‑275IW THX Certified Select In‑Wall Speakers ($349.99 MSRP) feature a premium, high-excursion 6.5-inch woofer, 50mm silk dome midrange driver, and 25mm silk dome tweeter. The 6.5-inch high excursion woofer features a long fiber pulp cone, NBR surround, and is designed with a shorting ring to minimize distortion, while the midrange driver operates in the 550 Hz to 3.1 kHz range to improve overall power handling, lower distortion, and improve polar response.

For larger rooms, Monolith THX-465IW THX Certified Ultra 3-Way In-Wall Speakers ($699.99 MSRP) upsize the THX-275IW by adding three more premium, high-excursion 6.5-inch woofers to the mix (for a total of four). Combined with a 50mm silk dome midrange driver and 25mm silk dome tweeter, these speakers deliver massive full-range sound that’s accurate and perfectly balanced, according to the company. Since these speakers feature more woofers, the midrange driver of this speaker operates in the 750 Hz to 3.4 kHz range to ensure a perfectly flat response, minimal distortion, and a higher SPL.

These new Monolith THX Certified in-wall speaker options are further refined by carefully selected fourth order Linkwitz-Riley crossover network acoustic filters. These crossovers minimize sonic frequency overlap, reduce distortion, and are an excellent choice to minimize off axis response errors near the crossover frequency. The heavy‑duty dog-ear mounting system makes installation easier, while the magnetically detachable, powder coated grille can be painted to match any room’s decor. Monoprice backs these Monolith in-wall speakers with a three-year warranty and 30-day no questions asked money back guarantee.

All Monolith THX Certified in‑wall and in‑room speakers utilize the same drivers and crossover components, allowing speakers to be mixed and matched to suit any room. Mixing Monolith in‑wall and in-room speakers for the left, center, right and rear channels will remain timbre matched across the Monolith THX family. Monolith THX Certified speakers can be paired with a Monolith THX Certified subwoofer.
