Used Meyer Sound SB-3F

The Meyer Sound SB-3F is a sound field synthesis loudspeaker built to address one of the most persistent challenges in large-scale sound reinforcement: maintaining clear intelligibility at great distances. It focuses on the 2 kHz to 9 kHz frequency range, where intelligibility is most critical, and is capable of projecting mid-high frequency energy over distances of up to 1 km.

The SB-3F uses sound field synthesis technology, combining multiple small point sources to produce a coherent, focused sound field. This approach delivers a narrow coverage angle, which concentrates energy along the intended throw path, reduces unwanted dispersion, and helps ensure minimal frequency loss over long distances compared with conventional loudspeaker designs.

The SB-3F is suited to large-scale sound reinforcement applications where high output and wide dynamic range are needed to handle signals with a high peak-to-average ratio, such as speech reinforcement across stadiums, arenas or outdoor events. It is designed to complement and integrate with other Meyer Sound products, particularly in systems requiring high intelligibility at long throw distances.

The SB-3F is made by Meyer Sound Laboratories, an American professional audio company founded in 1979 and based in Berkeley, California, known for loudspeakers, line arrays, subwoofers and electroacoustic systems used in sound reinforcement and fixed installation. The SB-3F sits within the specialist end of the Meyer Sound range, purpose-built to extend the intelligibility of large-scale Meyer Sound systems over distances that general-purpose loudspeakers cannot reliably cover.

When buying a second-hand SB-3F, confirm the purpose-built Meyer Sound drivers are functioning correctly and that there is no frequency loss at the high end of the 2 kHz to 9 kHz operating range, as this is the unit's core function. Check the enclosure condition and whether any rigging hardware is included.
