The Meyer Sound X-800 high-power studio subwoofer is designed primarily to provide additional low-frequency headroom in applications requiring very high monitoring levels coupled with extreme low-frequency transients. An excellent supplement to any high-level studio monitor, the X-800 also provides an ideal complement to Meyer Sound’s X-10 linear control room monitor. The X-800 houses two Meyer Sound long-excursion 18-inch drivers in a tuned, vented cabinet. The X-800 output rolls off well below 250 Hz, avoiding any adverse comb filtering effects that could be generated by the proximity of the dual drivers. A laser-trimmed differential input with high common-mode rejection enables long line-level signal runs using shielded, twisted-pair cable. As with all Meyer Sound self-powered products, onboard processing includes phase and frequency response correction filters and driver protection circuitry. An integral two-channel class AB/H amplifier with complementary MOSFET output stages supplies a total peak output of 1240 watts. Each amplifier channel features TruPower limiting technology to maximize loudspeaker reliability, minimize power compression and extend component life. An Intelligent AC power supply affords automatic voltage selection, EMI filtering, soft current turn-on and surge suppression. When used with the X-10, the X-800 is not intended to extend frequency response, as the X-10 is a full-range system. Rather, the X-800 extends low-frequency headroom by approximately 10 dB in the range from 25 Hz to the crossover point. The companion X-01 crossover module optimizes overall system response and allows connection of single or dual subs for stereo or 5.1 surround operation. Crossover points are selectable at 120, 100 and 80 Hz, and a single switch allows quick changeover from “pure” X-10 monitoring to subwoofer augmentation. A separate .1 channel input allows the system to be switched between stereo and 5.1 operation from the front panel; this switch can also be controlled remotely from the console. Though the sensitivity of the X-800/X-01 matches the X-10, the X-01 provides ±6 dB of gain to compensate for loading conditions. The X-800 subwoofer's premium birch plywood cabinet is coated with a durable textured finish. It is optionally available in a smooth medium-gloss black finish to match the X-10, complete with four rubber feet on each bottom corner and matching cups on the top corners for secure, aligned vertical stacking. A removable protective cloth covered wooden frame is attached to the front. Custom colors are available. Meyer Sound’s RMS remote monitoring system provides comprehensive system monitoring over a Windows-based network.
