VH Sub121H



This is a unique device especially designed and engineered for the reproduction of low frequencies at maximum sound pressure.

With its all horn loaded design, this system is equipped, in hybrid configuration (Horn & Reflex loaded), with a single 21in. transducer of latest generation with a 4.5in. voice coil Neodymium magnet.

Two extra-large Bass-reflex tunnels allow to further extend the system response towards low frequencies down to 30Hz. The contribution becomes bigger whenever the horn loading appears to be less efficient.

This combination, which is ideal in conjunction Horn loaded/Bass-reflex, ensures a great sound impact, high accurate reproduction and, at the same time, a deep, soft and prompt sound.

The Bass-punch is perfect and unrivaled. The incredibly high performances in terms of maximum sound pressure level make this system extremely effective when providing sound to spacious outdoor environments such as Arenas and Stadiums.

Certainly smaller than the VH Sub218H, the VH Sub121H can be also used in indoor environments of great dimensions such as Indoor Sports Arenas or Maxi-discos.

The employment of this device is strongly suggested whenever great energy, accuracy and a quick response to the transients in the reproduction of the lowest frequencies become mandatory.

Significant building criteria, together with the employment of the latest technologies and innovative materials, are able to guarantee great reliability and longevity.

The anti-scratch Polyurea final paint makes the cabinet extremely resistant to atmospheric agents.

It can be as well matched with all the most challenging Full-Range and Line Array of the VH Full-Range/VH Line-Array family.

It can be widely employed in Large Open Spaces, Arenas, Stadiums, Theaters, Conference Halls, Concert Halls and Large Scale Discos
