THX Certified Select In-Wall Speakers – Available immediately

Monolith’s new THX Certified Select and THX Certified Ultra in-wall speakers were meticulously engineered to ensure every seat in the room receives the best possible audio experience, says their creator.

Monolith THX‑275IW THX Certified Select In‑Wall Speakers ($349.99 MSRP) feature a premium, high-excursion 6.5in woofer, 50mm silk dome midrange driver and 25mm silk dome tweeter that combined deliver precise detail and the absolute best home theater dynamics, claims the maker.

The 6.5in high excursion woofer features a long fiber pulp cone, NBR surround, and is designed with a shorting ring to minimise distortion, while the midrange driver operates in the 550Hz to 3.1kHz 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 6.5in woofers to the mix (for a total of four). Combined with a 50mm silk dome midrange driver and 25mm silk dome tweeter, Monolith says these speakers deliver massive full-range sound that’s accurate and perfectly balanced. Since these speakers feature more woofers, the midrange driver of this speaker operates in the 750Hz to 3.4kHz 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 minimise sonic frequency overlap, reduce distortion, and are a strong choice to minimise off axis response errors near the crossover frequency. The heavy‑duty dog ear mounting system makes installation straight-forward, 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.

“When a speaker earns THX Certification, you can be sure that it will deliver an ideal home theater listening experience,” says Steve Martz, global head of THX Certification, THX Ltd. “The Monolith line of premium audio products from Monoprice is robust with THX Certified options. These new Monolith in-wall speakers follow suit and meet the strict THX performance and listening standards, giving customers even more excellent speaker options to consider for their living rooms and home theaters.”

All Monolith THX Certified in‑wall and in‑room speakers use 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. For the ultimate listening experience, Monolith THX Certified speakers should be paired with a powerful Monolith THX Certified subwoofer.
