18" CARBON FIBRE DIAPHRAGM

The powerful push pull motors are capable of handling 500 amperes, converting over 1,000 watts of electro magnetic energy into kinetic energy. As a result, the Torus cone is subjected to huge compression and decompression forces. In order to deal with these forces, Wilson Benesch developed a carbon fibre diaphragm.

Carbon fibre is renowned for its high strength-to-weight ratio, and this property makes it the ideal for the Torus cone. A novel multi-axial carbon fibre weave developed by the company is used to create a phenomenally stiff, light and highly damped diaphragm.

Thus, despite its relatively small size, the Torus boasts an 18” diaphragm, that weighs in at just 18g and yet is capable of displacing huge volumes of air instantaneously. Transients are handled with ease, giving rise to the chest moving kick drum and attack, impossible to achieve with a conventional subwoofer design.

PUSH / PULL DRIVE

Huge 82 mm diameter motor coils are deployed on both sides of the diaphragm in order to provide for perfectly balanced kinetics. This novel “push pull” is often seen in other engineering applications, where maximum control and power transfer is required.

While the Torus motor converts electrical energy from the amplifier into kinetic energy in the same way as a regular woofer, the fundamental difference comes from a push-pull motor design. Unlike a common subwoofer that relies upon high hysteresis suspension to reset the cone to its resting point, the cone position of the Torus is dictated at all times by electromagnetism. This enables the Torus to reproduce low frequency sound with a stunning degree of precision and allowing the reliable communication of transient low frequency information.

The powerful push-pull motor is capable of handling 500 amperes, converting over 1000 watts of electromagnetic energy into kinetic energy, generating huge compression and decompression forces.

NdFeB MAGNETS

Two Neodymium Rare Earth Magnets are deployed either end of the core to create a dual motor push / pull drive.

CORE

As its name suggests, the Core is at the heart of the Torus design.

It is a formidable structural element of Brunelian proportions.

Weighing in at over 16 kg, the precision machined assembly,

combines with high energy Rare Earth magnets to create a dual

motor / push pull drive.

The Core also provides a number of other important benefits that

are elaborated upon below:

1. Converts electrical energy into kinetic energy.

2. High capacity metal sink conducts all structural borne resonant energy directly to ground with zero reference to the outer enclosure.

3. High metal mass efficiently conducts all heat away from the coils.

INTERNAL BRACE

A precision laser cut steel brace resides beneath the slick Piano Black Gloss Torus enclosure. This component stiffens the cylindrical form of the enclosure further.

CYLINDRICAL CABINET

Finished to the same exacting standards as the rest of the Geometry Series, the Torus Infrasonic Generator comes in a slick and understated Piano Black Gloss finish.
