X-800C High-Power Cinema Subwoofer

The loudspeaker shall be a self-powered, sub-bass system. The transducers shall consist of two 18-inch cone drivers (3-inch voice coil) each rated to handle 600 AES* watts. 

The loudspeaker shall incorporate internal processing electronics and a two-channel amplifier. Each amplifier channel shall be class AB/H with complementary MOSFET output stages. Burst capability shall be 1240 watts total with nominal 8-ohm resistive load. Distortion (THD, IM, TIM) shall not exceed 0.02%. Protection circuits shall include TruPower limiting. The audio input shall be electronically balanced with a 10 kOhm impedance and accept a nominal 0 dBV (1 V rms) signal (20 dBV to produce maximum SPL). Connectors shall be XLR type male and female or VEAM all-in-one. RF filtering shall be provided, and CMRR shall be greater than 50 dB (50 - 500 Hz).

Performance specifications for a typical production unit shall be as follows, measured at 1/3-octave resolution: Operating frequency range shall be 20 Hz to 200 Hz. Phase response shall be ±30° from 35 Hz to 120 Hz.

The internal power supply shall perform automatic voltage selection, EMI filtering, soft current turn-on and surge suppression. Powering requirements shall be nominal 100 V, 110 V or 230 V AC line current at 50 Hz or 60 Hz. UL and CE operating voltage ranges shall be 95 to 125 V AC and 208 to 235 V AC. Current draw during burst shall be 15 A rms at 115 V AC, 8 A rms at 230 V AC and 18 A rms at 100 V AC. Current inrush during soft turn-on shall not exceed 7 A at 115 V AC. AC power connectors shall be L6-20 or IEC 309 male.

The loudspeaker shall optionally incorporate the electronics module for Meyer Sound’s RMS remote monitoring system.

Loudspeaker components shall be mounted in a premium birch plywood enclosure with a durable textured finish (optional smooth medium-gloss black finish available). Dimensions shall be 31.00" wide x 40.00" high x 21.33" deep (787 mm x 1016 mm x 542 mm). Weight shall be 221 lbs (100.24 kg).

The loudspeaker shall be the Meyer Sound X-800C high-power cinema subwoofer.
