Meyer Sound 750-LFC-RMS-3 15" Subwoofer

LINA and 750-LFC loudspeakers are professionally made capable to work along with Meyer Sound’s RMS™ remote monitoring system, which is capable of providing a comprehensive monitoring of system parameters from a Mac® or Windows®-based computer.

LINA’S IDEAL COMPANION

The 750-LFC is professionally designed as a very compact low-frequency control element effectively complements LINA arrays in the lower end of the spectrum that comes along with exceptional low frequency headroom. Boasting an incredible power-to-size-ratio for such a compact cabinet, the 750-LFC is LINA’s ideal and extremely versatile companion, and capable to 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 comes ensuring that 750-LFC systems are capable to reproduce low frequencies at high continuous levels with clarity, punch, and extremely low distortion.

SMALL, LIGHTER, SCALABLE

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

Applications:

  • Scalable low-frequency control for touring or corporate applications, or fixed installations
  • Clubs, theaters, houses of worship, corporate AV, and theme parks
  • Low-frequency complement for LINA, LEOPARD and ULTRA systems

Features:

  • Compact cabinet with small footprint and extraordinary power-to-size ratio
  • High peak power output with extremely low distortion
  • Exceptional linearity, transient reproduction, and low-frequency clarity
  • Self-powered design for simplified setup and increased reliability
  • Stackable and flyable in regular and cardioid arrays with splay options
  • Integral pole-mount receptacle to facilitate pairing with LINA or ULTRA Series loudspeakers
