MEYER SOUND HITS NEW LOWS WITH VLFC

has announced the introduction of the , the latest addition to its Leo family of line systems. VLFC is the first large-scale system specifically engineered to create visceral impact at frequencies below the threshold of hearing. By focusing energy into a narrow band between 30Hz and 13Hz, VLFC is uniquely 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 sound.

The VLFC is a self-powered system housing two low resonant frequency 18-inch cone drivers. The on-board power is supplied by a two-channel Class AB/H bridged amplifier with complementary MOSFET output stages for high peak power and clean transient reproduction even at extreme operating levels. Cabinet porting and internal baffling have been optimised to deliver maximum acoustic output in one octave that extends across the lower limit of human hearing.

“You actually feel the effect of the VLFC much more than you hear it,” explains 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.”

The VLFC shares the same exterior footprint as Meyer Sound’s 1100-LFC low frequency control element, allowing use of the same rigging grids and caster frames. When the VLFC is paired with the 1100-LFC, the combination produces linear, coherent bass response from 13Hz to 100Hz.

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 explosive 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.
