Overview
The X‑1100C High‑Power Cinema Subwoofer is a self‑powered loudspeaker defined by its sonic linearity in reproducing low‑frequency transients at high continuous output levels with very low distortion. This ultra‑low distortion, coupled with exceptional headroom, makes the X‑1100C a flexible tool for adding low‑end frequencies in larger‑scale cinemas or for cinemas that require high power but have limited real estate for loudspeaker installation.
An optimally tuned, vented cabinet houses the X‑1100C’s two 18‑inch, long‑excursion cone drivers. The loudspeaker’s 28 Hz to 180 Hz operating frequency range complements other Meyer Sound cinema loudspeakers, such as the Acheron screen channel loudspeakers and the HMS cinema surround loudspeakers, allowing for seamless integration. For full SMPTE compliance, the X‑1100C pairs perfectly with Meyer Sound’s VLFC (Very Low Frequency Control Element), with its range of 13–30 Hz, to extend the low end to subsonic levels.
The unit’s power amplifier operates at voltages from 208 to 235 V AC, at 50–60 Hz. TruPower® limiting ensures maximum driver protection, minimizing power compression while yielding high constant output under high continuous and peak power conditions. A single, field‑replaceable module located on the rear of the cabinet contains the amplifier, control electronics, and power supply.
Meyer Sound’s RMS™ remote monitoring system module comes standard with all X‑1100Cs and provides comprehensive monitoring of system parameters from a host computer running Compass® control software via the optional RMServer™ interface.
To guarantee optimum performance of the X‑1100C, Meyer Sound recommends using the MAPP™ system design tool. This intuitive, cross‑platform application accurately predicts directional patterns, frequency and impulse responses, and linear peak SPL, ensuring that systems deliver the required coverage and SPL.
The X‑1100C cabinet includes protective plastic skids on the bottom that securely align with the cabinet’s top slots, facilitating stacking. Meyer Sound constructs the X‑1100C cabinet with premium multi‑ply birch and coats it with a slightly textured black finish. A powder‑coated, hex‑stamped steel grille with acoustical black mesh protects the unit’s drivers. Custom color finishes for applications with specific cosmetic requirements are available.
The optional MCF‑1100 caster frame facilitates three‑cabinet stacking of the X‑1100C for secure movement. Optionally available durable nylon covers accommodate stacks of two or three X‑1100Cs for protected storage.
