Meyer HMS-12 Cinema Speaker Set of 7 with MPS488HPP Power Supply and 6 Mounting Brackets
Meyer Sound HMS-12 Powered Cinema Surround Speaker
The HMS-12 high-power cinema surround loudspeaker, with IntelligentDC technology, is optimized for use in cinemas, theatres, screening rooms, and other surround applications. The self-powered, full-range HMS-12 maintains a wide dynamic range, exceptional fidelity, and clarity during the most demanding of digital soundtracks. As part of Meyer Sound’s Cine-Studio series, the HMS-12 integrates seamlessly with Acheron®screen channel loudspeakers, as well as with other HMS surround loudspeakers. Boasting a wide frequency range of 59 Hz to 18 kHz and a maximum peak SPL of 133 dB at 1 meter, with very low distortion, the HMS-12 delivers the full intensity and nuance of cinema surround channels to every listener without compromise.
