Meyer Sound launches ‘very low frequency’ line array

As well adding low frequency impact to audio in clubs and music concerts, the VLFC can also add special effects in cinemas and theme park attractions

Meyer Sound has introduced a ‘very low frequency control’ element (VLFC) to its LEO family of line array systems.

VLFC is the first large-scale loudspeaker system specifically engineered to create impact at frequencies below the threshold of hearing.

By focusing energy into a narrow band between 30 Hz and 13 Hz, VLFC is capable of generating extreme variations in air pressure that are sensed by the entire body as compression waves while those frequencies at the upper end of its range are perceived as thunderous bass sound.

“You actually feel the effect of the VLFC much more than you hear it,” explained Pablo Espinosa, Meyer Sound’s vice president of research and development and chief loudspeaker designer. “It truly is a chest-slamming experience. And because the VLFC’s very long wavelengths have lesser impact on hearing and fall below most weighting curves, you can add bone-rattling power to your performance without running afoul of noise limits.”

Applications for the VLFC include adding very low frequency, visceral impact to hard rock and electronic dance music in concerts, festivals and clubs. The VLFC also adds impact to special effects in cinemas, themed spectacles, and theme park attractions. A limited early production run of VLFC elements was supplied for Metallica’s ongoing Worldwired tour, where as many as 42 VLFC cabinets created a forceful impact that was felt throughout large stadiums.

The VLFC is currently shipping on Meyer Sound’s regular order turnaround schedule.
