Monolith THX-certified 5.1 home theater speaker system introduced by Monoprice to rock your movies and games


monolith, the high-end audio brand of Monoprice™, announced the launch of the new THX®-Certified M518HT 5.1 Home Theater System – an affordable, small-footprint home theater speaker system designed for smaller rooms and gaming systems. Featuring five premium in-wall satellite speakers and an 8” powered subwoofer, this system has been THX® certified and compact to ensure listeners experience incredibly dynamic, detailed and crystal clear sound to reproduce audio as the creator intended it intended to be enjoyed.


“When it comes to watching movies or playing video games at home, nothing beats a powerful, great-sounding multi-channel surround sound system. The M518HT 5.1 home theater speaker system expands our range of previously announced THX certified speakers and subwoofers designed for home theater rooms and larger living rooms, serving as an ideal solution for smaller spaces such as bedrooms, playrooms and dens without compromising on excellence what our THX-certified Monolith products are known for,” said Hobie Sechrest, Monolith Business Unit Manager at Monoprice.


Compatible with other high quality home theater receivers and amplifiers, the M518HT is a compact system that fills rooms with massive, dynamic and immersive full-range sound. The system includes five full-range satellite speakers, each equipped with a 4.5-inch concentric high-excursion driver with an inserted 20mm silk-dome tweeter and optimized waveguide. Although small, these MDF-encased, precision-tuned cube-shaped speakers deliver a flat frequency response down to 80Hz. Their small footprint and uncompromising performance make them an ideal match for many home theater systems around the world. Adding to the appeal of this system, each speaker features a keyhole mounting slot and spring-loaded cable connectors, making them easy to install.


The MH18HT system also brings big bass to the party, with a compact but powerful 8-inch down-firing subwoofer with powered subwoofer. Driven by a powerful 150 watt DSP-tuned amplifier, this subwoofer maintains a flat and seamless frequency response down to 30Hz (-10dB) and has been tuned to perfectly balance the satellite speakers. To ensure ideal performance in rooms of all sizes, the subwoofer features three adjustment options for crossover, phase and level, allowing customers to tailor their bass experience. The subwoofer also features three EQ settings to ensure the best bass response for different room types, with the THX® EQ setting offering the lowest distortion and cleanest sound for listeners who want to ensure they’re experiencing the audiophile prowess of THX to use.


Backed by a five-year warranty, a 30-day money-back guarantee, Monolith’s proven reputation for excellence, and the THX Gold Seal of Approval, the Monolith M518HT THX-certified 5.1 home theater speaker system offers movie fans and gamers a powerful, cinematic listening experience impress and inspire in equal measure.


“While maintaining the Monolith brand’s track record of delivering quality audio products to the masses, our engineers have rigorously tested and validated the new Monolith M518HT 5.1 system for its ability to deliver a truly outstanding cinematic listening experience. With THX certification, customers can be assured that this compact system will deliver spectacular performance,” said Steven P. Martz, Vice President, Global Technology, THX Ltd.
