Part of Meyer Sound's EXP cinema series, the X-400C compact subwoofer boosts low- frequency headroom in cinema applications and other fixed installations. The linear, self-powered X-400C offers similar sonic characteristics as the X-800C subwoofer – low-frequencies down to 20 Hz, clean, punchy transients, and excellent phase coherence – though in a more compact cabinet that can be installed singly or as multiple units.

The X-400C is comprised of a single 18-inch low-frequency, long-excursion cone driver housed in an optimally tuned, vented cabinet and powered by a single-channel amplifier. Onboard processing includes driver protection circuitry, low-pass filtering, and correction filters for flat phase and frequency responses.

The IntelligentACTM power supply affords automatic voltage selection, EMI filtering, soft current turn-on, and surge suppression.

The X-400C integrates seamlessly with other EXP cinema loudspeakers, including the Acheron screen channel loudspeakers and HMS surround loudspeakers.

Meyer Sound's optional RMS remote monitoring system provides comprehensive monitoring of system parameters on a Mac® or Windows® based computer.

The X-400C cabinet is constructed of premium birch plywood and coated with a low-gloss, black-textured finish. The cabinet includes attachment points for an optional grille frame with black cloth.
