Operating Instructions — X-800C
High-Power Cinema Subwoofer

The X-800C cinema subwoofer boosts low-frequency headroom in Meyer Sound cinema installations. The linear, self-powered X-800C offers low-frequency output down to 20 Hz with clean, punchy transients, and provides excellent phase coherence for smooth transitions between screen channels and LFE channels.
The X-800C includes two Meyer Sound long-excursion, high-efficiency 18-inch drivers housed in an optimally tuned, vented cabinet. Output rolls off well below 250 Hz, avoiding any adverse comb filtering effects from the proximity of the dual drivers.

X-800C Cinema Subwoofer
The drivers are powered by a two-channel class AB/H amplifier with complementary MOSFET output stages. A total output of 1240 Watts ensures the system has ample headroom to accommodate the lowest frequencies of the most extreme digital soundtracks.
Each amplifier channel features TruPower® limiting to maximize loudspeaker reliability, minimize power compression, and extend component life. The Intelligent AC™ power supply affords automatic voltage selection, EMI filtering, soft current turn-on, and surge suppression.
A laser-trimmed differential input with high common-mode rejection enables long line-level signal runs with shielded, twisted-pair cable. As with all Meyer Sound self-powered loudspeakers, processing correction filters for flat phase and frequency responses.
Integration of the X-800C within Meyer Sound cinema installations is easily achieved with the MAPP System Design Tool (see meyersound.com/products for more details).

Meyer Sound’s optional RMS™ remote monitoring system provides comprehensive monitoring of system parameters on a Windows®-based computer.
The X-800C cabinet is constructed of premium birch plywood and coated with a durable, medium-gloss, smooth black finish. A textured finish is optionally available.
