MX3068 — Cinema Screen Speaker

The MX3068 is a passive three-way screen-channel loudspeaker for medium and large commercial cinema auditoria, intended for the L/C/R main channels behind acoustically transparent screens. A single 18-inch low-frequency driver, a dedicated 6.5-inch cone midrange and a 2-inch compression driver share one cabinet, covering 40 Hz–20 kHz (±3 dB, 2π) with usable extension to 28 Hz; an integrated mid/high horn raises sensitivity and provides 100° × 60° nominal coverage.

The 18-inch woofer uses a SOVOX ADM™ oil-coated, cloth-edged loose-pressed paper cone with a 75.5 mm voice coil and 22.5 mm winding. A dedicated 6.5-inch cone driver carries the dialogue band, and the 2-inch compression driver combines a 44.4 mm CCAW voice coil with a titanium diaphragm. Passive crossovers at 500 Hz and 2.8 kHz allow one amplifier channel to drive the complete three-way system at an 8-ohm nominal load, reducing amplifier channels and wiring. The one-piece bass-reflex enclosure (PVC-laminated MDF with integrated horn) measures 670 × 983 × 388 mm (W × H × D) and weighs 47 kg; its 388 mm depth suits the restricted space behind screens, with screen-frame mounting or guided suspension.
