The HMS-15 high-power surround loudspeaker is optimized for use in cinemas, theatres, screening rooms, or any surround application or immersive cinema format. The self-powered, full-range HMS-15 maintains a wide dynamic range, exceptional fidelity, and clarity during the most demanding of digital soundtracks. As part of Meyer Sound's EXP cinema series, the HMS-15 integrates seamlessly with Acheron® screen channel loudspeakers, as well as with other HMS surround loudspeakers. Boasting a wide frequency range of 50 Hz to 18 kHz and a maximum peak SPL of 133 dB at 1 meter with very low distortion, the HMS-15 delivers the full intensity and nuance of cinema surround channels to every listener without compromise.

The HMS-15's transducers include a 15-inch low-frequency, long-excursion cone driver and a 3-inch diaphragm high-frequency compression driver on a constant-directivity 80-degree horizontal by 50-degree vertical horn that delivers exceptional consistency. The proprietary drivers-designed and manufactured at Meyer Sound's headquarters in Berkeley, California -are powered by two channels of onboard amplification that include an active crossover, driver protection circuitry, and correction filters for flat phase and frequency responses.

The versatile HMS-15 can be mounted on walls or ceilings at fixed or adjustable angles with the optional wall-mount brackets or U-bracket, allowing the unit to be deployed per the requirements of any surround application or immersive cinema format.

The HMS-15 requires two channels of DC power from an MPS-488HP external power supply. Powering the unit from an external source eliminates the need for wiring conduits while still preserving the advantages of self- powered, bi-amplified loudspeaker systems. For even greater flexibility, the HMS-15AC model is available for AC installations. Meyer Sound's RMS remote monitoring system provides comprehensive monitoring of system parameters on a Mac® or Windows®-based computer. RMS is available for the HMS-15 via the RMS option for the MPS-488HP external power supply. RMS is available for the HMS-15AC as an onboard loudspeaker option.

Meyer Sound's industry leading self-powered loudspeaker technology not only delivers unparalleled and consistent audio fidelity but also simplifies installation, whether designing new rooms from scratch or adding surround channels to existing setups. The HMS-15's textured finish and black cloth grille blend smartly with any theatre decor.
