Meyer Sound 750-LFC-3-RIGGING, 15" Subwoofer, Rigging, 3-Pin Input

Meyer Sound 750-LFC-3-RIGGING, 15" Subwoofer, Rigging, 3-Pin Input

The Meyer Sound 750-LFC-3-RIGGING very compact low-frequency control element effectively complements LINA arrays in the lower end of the spectrum with exceptional low frequency headroom. Boasting an incredible power-to-size-ratio for such a compact cabinet, the Meyer Sound 750-LFC-3-RIGGING is LINA’s ideal and extremely versatile companion, and can also complement ULTRA systems.

NEW, IMPROVED AMPLIFIER

A newly-designed class D amplifier affords unprecedented power for its size, and along with its signal processing, it ensures that Meyer Sound 750-LFC-3-RIGGING systems reproduce low frequencies at high continuous levels with clarity, punch, and extremely low distortion.

SMALL, LIGHTER, SCALABLE

The Meyer Sound 750-LFC-3-RIGGING offers the same sonic linearity as Meyer Sound’s award-winning 900-LFC low-frequency control element in a smaller, lighter cabinet, making it ideal for building scalable systems to suit touring and corporate applications or fixed installations.
