Overview

The Monoprice Premium 5.1.4 Dolby Atmos Home Theater System is designed to bring immersive, multi-dimensional audio to home environments without requiring in-ceiling speaker installation. The system achieves its 5.1.4 channel configuration through upward-firing drivers built into the satellite speakers, which bounce sound off the ceiling to create the overhead audio channels that Dolby Atmos soundtracks demand. This approach makes Atmos accessible in rooms where ceiling-mounted speakers are impractical, whether due to rental restrictions, construction constraints, or simply the desire for a simpler setup.

The system is anchored by a powered subwoofer with an 8-inch downward-firing driver and a 200-watt amplifier, providing the low-frequency foundation for movies and music. The subwoofer's variable crossover (40–150Hz) and phase control switch give users the ability to dial in bass response relative to the room and the rest of the system. The compact satellite speakers measure just 4.5" x 4.5" x 5.3" each, and both the satellites and the center channel include 1/4" x 20 threaded mounts for easy integration with standard speaker stands and wall brackets. The subwoofer accepts both line-level and speaker-level inputs, ensuring compatibility with any amplifier or receiver. The entire system is fully compatible with Dolby Atmos-enabled receivers and soundtracks, and is backed by Monoprice's 1-year replacement warranty and 30-day money-back guarantee.
