Meyer Sound HMS-15AC Cinema Surround Loudspeaker - 09.242.001.08

Product Overview

The Meyer Sound HMS-15AC cinema surround loudspeaker is the AC-powered version of the HMS-15, built for large cinemas, premium private theaters, screening rooms, and immersive surround applications. Designed to complement Meyer Sound Acheron screen channel loudspeakers, it delivers wide dynamic range, exceptional fidelity, and precise clarity through the most demanding digital soundtracks. Its onboard Intelligent AC power supply removes the need for an external DC supply, simplifying deployment where local mains power is available. A 15-inch cone driver and 1000 W peak amplifier produce 132 dB linear peak SPL for the largest surround zones.

Product Description

The HMS-15AC pairs one 15-inch long-excursion cone driver with a 3-inch diaphragm compression driver in a premium multi-ply birch enclosure with a slightly textured black finish. An onboard two-channel amplifier integrates an active crossover, driver protection, and correction filters for flat phase and frequency response, while a constant-directivity horn maintains uniform 80-degree by 50-degree coverage. Its Intelligent AC power supply provides automatic voltage selection, EMI filtering, soft current turn-on, and surge suppression, accepting 100 to 240 V AC at 50 to 60 Hz through a powerCON 20 input with loop output. Audio connects via XLR 3-pin female input with male loop output, and an optional onboard RMS remote monitoring module reports loudspeaker parameters to a host computer. For installations standardized on IntelligentDC distribution, the HMS-15 offers identical acoustic performance from an external MPS supply. The acoustically transparent, detachable black cloth grille blends discreetly with theater decor.

Key Features

• Intelligent AC Power Supply — The onboard supply provides automatic voltage selection, EMI filtering, soft current turn-on, and surge suppression for direct AC operation.
• Single 15-Inch Cone Driver — One 15-inch long-excursion cone driver delivers the highest low-frequency output in the HMS family.
• 3-Inch Compression Driver — A 3-inch diaphragm compression driver on a constant-directivity horn extends high-frequency response to 18 kHz.
• 1000 W Peak Amplifier — The onboard two-channel amplifier produces 1000 W peak with an active crossover, driver protection, and correction filters.
• Linear Peak SPL of 132 dB — The HMS-15AC produces 132 dB linear peak SPL with crest factor greater than 16 dB measured with M-noise.
• powerCON 20 and XLR Connectivity — A powerCON 20 input with loop output and XLR 3-pin audio with loop output simplify daisy-chained installation.
• Optional RMS Monitoring — An optional onboard RMS remote monitoring system module reports loudspeaker parameters to a Mac or Windows computer.

Frequently Asked Questions

Does the HMS-15AC need an external power supply?
No. Unlike the IntelligentDC HMS-15, the HMS-15AC has an onboard Intelligent AC power supply and connects directly to 100 to 240 V AC mains through a powerCON 20 input.

What is the difference between the HMS-15 and HMS-15AC?
The HMS-15AC is AC powered with an onboard supply, while the HMS-15 is IntelligentDC powered from an external MPS supply. Both share the same drivers, coverage, and 132 dB peak SPL.

Does the HMS-15AC support remote monitoring?
Yes, optionally. An onboard RMS remote monitoring system module can report loudspeaker parameters to a Mac or Windows computer.

Is the HMS-15AC covered by a warranty?
Yes. The HMS-15AC is covered under Meyer Sound's standard product warranty. For details, please contact us.
