M330T — Cinema Screen Speaker

The M330T is a passive two-way screen channel loudspeaker in the SOVOX M Series for compact and medium-size cinema auditoria, covering behind-screen main channels, multiplex auditoria and screening or dubbing rooms. Three 12-inch low-frequency drivers and a 3-inch compression driver are integrated into a single bass-reflex enclosure with a built-in horn, covering 50 Hz–18 kHz (±3 dB, half-space) with a 38 Hz–20 kHz usable range and 90° × 50° nominal coverage.

The three 12-inch drivers sit side by side in one horizontal cabinet, keeping overall height to 787 mm for installations with limited vertical space behind the screen; the LF drivers use ADM™ coated-cloth-edge paper cones that balance stiffness, damping and durability. The 3-inch titanium-diaphragm compression driver combines a large voice coil with the HLMS™ copper-sleeve-plus-aluminium-ring dual shorting structure, and its power handling supports prolonged high-level operation. An internal 2.0 kHz passive crossover integrates the low- and high-frequency sections for single-amplifier drive. The cabinet weighs approx. 40 kg and supports screen-frame mounting or guided suspended installation; the 2.7-ohm nominal load requires amplifier current capability, cable gauge and protection settings to be verified during system design.
