Product Overview
LINA’S IDEAL COMPANION
The 750-LFC 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 750-LFC 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 750-LFC systems reproduce low frequencies at high continuous levels with clarity, punch, and extremely low distortion.
SMALL, LIGHTER, SCALABLE
The 750-LFC 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.
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
