Timpani, Kick drums, kettle drums, these are all great examples of instruments that inspired the innovation of Wilson Benesch infrasonic technologies. Each musical instrument creates low frequency sound with attack and dynamics that hit you in the chest.

The IGx seeks to recreate this experience of live music using innovative technologies including the push-pull motor design, a rounded geometric enclosure that mimics these instruments and a super lightweight Carbon Fiber – Polyethylene Terephthalate diaphragm. By combining these highly evolved technologies, Wilson Benesch delivers the ultimate solution – lightning fast, highly integrated, perfectly resolved low frequency sound that physically moves the listener.

Launched in 2006, the original Torus Infrasonic Generator remains a significant departure from all prior art. Unlike all design’s prior, the Wilson Benesch Torus Infrasonic Generator eliminated the cabinet from any and all structural responsibilities. Instead, Wilson Benesch placed a 16kg Steel Core at the heart of the Torus Infrasonic Generator. The core legislates that all energy from the two push-pull Neodymium motors is grounded. Ingeniously simple. Totally unique.

Through collaboration with two leading companies in the field of fiber weaving and composite design, a new fabric was invented to achieve what was previously impossible. The Carbon Fiber –  Polyethylene Terephthalate diaphragm is geometrically optimized and realized from a woven material that incorporates both the fiber as well as the resin matrix. This material is woven exclusively in Europe for Wilson Benesch. The geometrically optimized, sub-100g, Carbon Fiber – Polyethylene Terephthalate diaphragm is a marvel of engineering. The lightweight diaphragm can support 1000 times its own mass, a testament to the stiffness of the structure. The diaphragm at the heart of the new IGx sets the industry standard both in terms of stiffness and damping. It is a peerless solution that enables the reproduction of lightning-fast Timpani.

Inspired by the instruments that it aspires to reproduce, the IGx’s circular external structure is the geometrically perfect shape. The absence of flat panels or material redundancy is notable, taking its place is the curvature that defies cabinet resonance, a perfect example of form follows function. 

The new IGx represents a new level of refinement, quality and performance. Delivering music enthusiasts a new level of low frequency sound reproduction within their personal home audio system.
