Monoprice 138546 Monolith THX-465T: Dolby Atmos Tower Speaker

The Monoprice Monolith THX-465T is a floor-standing tower speaker designed to meet the demanding standards of THX Certified Ultra, a certification that validates its ability to deliver reference-level audio in rooms up to 3,000 cubic feet. With 6.5-inch woofer drivers, a dedicated crossover network, and premium driver components, the THX-465T produces a wide frequency response with controlled dispersion and low distortion — qualities that are essential for accurately reproducing both the subtle details in music and the explosive dynamics of movie soundtracks.

What sets the THX-465T apart from many traditional tower speakers is its integrated up-firing Dolby Atmos-enabled driver. Mounted on top of the cabinet, this driver bounces height-channel audio off the ceiling to create an overhead sound field, eliminating the need for dedicated in-ceiling or elevation speakers in an Atmos-compatible surround system. The cabinet itself is a serious piece of engineering at 82 pounds and 57.5 inches tall, built with mass and rigidity to minimize unwanted resonance and coloration. As a passive speaker, it relies on an external amplifier or AV receiver for power, giving users the flexibility to pair it with electronics that match their performance expectations and budget. For home theater enthusiasts seeking THX-grade accuracy with Atmos capability in a single tower design, the Monolith THX-465T represents a compelling option from Monoprice's premium audio lineup.
