HMS-15 Cinema Surround Loudspeakers

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. The HMS-15 requires two channels of DC power from an MPS-488HP or MPS-482HP external power supply. The HMS-15AC model is available for AC powered installations.

The HMS-15AC is an AC-powered version of the HMS-15. Its Intelligent AC™ power supply provides automatic voltage selection, EMI filtering, soft current turn-on, and surge suppression. The HMS-15AC is optionally available with its own onboard RMS™ remote monitoring system module for comprehensive monitoring of loudspeaker parameters from a Mac or Windows-based computer.
