MS1201 — Cinema Surround Speaker

The MS1201 is a coaxial two-way surround loudspeaker in the MS Series for the side-wall and rear-wall channels of medium-to-large auditoriums, suitable for wall or ceiling mounting, and for ceiling suspension on threaded rods as a height channel for immersive formats such as Dolby Atmos. It pairs a 12″ coaxial driver with a 2″ dome HF section and delivers 52 Hz–20 kHz (±3 dB) and 100° × 100° nominal coverage from a 289 mm deep bass-reflex enclosure.

The 12″ coaxial driver places low and high sections on one axis. The 4 Ω nominal impedance governs how many cabinets can share one channel and the cable size required, so amplifier current capability and cable loss must be checked at system design; 96 dB sensitivity and a 270 W AES 100-hour rating define its output capability. The U-shaped bracket provides horizontal aiming for direct side-wall mounting or ceiling suspension; the bass-reflex MDF cabinet carries a PVC laminate finish and weighs 14.5 kg net.
