Meyer Sound 1100-LFC, 2x 18" Subwoofer

Meyer Sound 1100-LFC, 2x 18" Subwoofer

The Meyer Sound 1100-LFC is a self-powered subwoofer defined by its sonic linearity in reproducing low frequency transients at high contrinous output levels with every low distortion. The Meyer Sound 1100-LFC has ultra-low distortion, coupled with exceptional headroom and optimized rigging options, makes the Meyer Sound 1100-LFC a flexible tool for low-end directional applications for large-scale tours and installations. To guarantee optimum performance, the Meyer Sound 1100-LFC has a Meyer Sound's MAPP™ system design tool. This intuitive, cross-platform application is accurately predicts directional patterns, frequency and impulse responses, and linear peak SPL for 1100-LFC systems, ensuring that systems deliver the required coverage and SPL. Also, the Meyer Sound 1100-LFC is optimally tuned, vented cabinet houses with two 18-inch, long excursion cone drivers. The loudspeaker's 28 Hz to 100 Hz operating frequency range complements LEO®, LEOPARD™, LYON™, JM‑1P, and other Meyer Sound loudspeakers, allowing it to integrate seamlessly with line arrays and curvilinear arrays.
