Overview
The Meyer Sound X-800C High-Power Cinema Subwoofer is designed to provide very low-frequencies with ample headroom in critical applications. The X-800C excels in environments requiring very low distortion, extended bandwidth and extreme low frequency transients.
The X-800C is a linear, powerful self-powered subwoofer offering excellent phase coherence for smooth transitioning from screen channels to low-frequency effects (LFE). The X-800C delivers extended low frequency output down to 20 Hz with clear, punchy transients even at very high levels.
The X-800C houses two Meyer Sound long excursion, high efficiency 18-inch drivers in an optimally tuned, vented cabinet. The X-800C output rolls off well below 250 Hz, avoiding any adverse comb filtering effects that could be generated by the proximity of other X-800C subwoofers when used in arrays.
An integral two-channel class AB/H amplifier with complementary MOSFET output stages supplies a total output of 1240 Watts, providing the system with sufficient headroom to accommodate lowest frequencies of the most extreme digital soundtrack’s.
Each amplifier channel features TruPower® limiting technology to maximize loudspeaker reliability, minimize power compression and extend component life. An Intelligent AC™ power supply provides automatic voltage selection, EMI filtering, soft current turn-on and surge suppression. Sophisticated onboard processing includes phase and frequency response correction filters. This self-powered design not only assures consistent results but also simplifies installation in both new and existing rooms.
The X-800C subwoofer’s premium birch plywood cabinet is coated with a durable medium gloss finish. Meyer Sound’s optional RMS™ remote monitoring system allows comprehensive monitoring of loudspeaker parameters from a Mac® or Windows®-based computer running Compass® control software.
