Torus Infrasonic Generator

Torus Infrasonic Generator

The Torus places an 18” light-weight, super-stiff, multi-axial Carbon Fibre cone at the end of a phenomenally powerful push-pull motor. Unlike a common subwoofer that relies upon a high hysteresis suspension to reset the cone to zero, the cone position in the Torus is dictated to at all times by electromagnetism. The result is low frequency sound with absolute precision and integration across the frequency range.

Description

At the heart of the Torus is the core, a formidable 16kg precision machined steel column, with the two large rare earth magnets of the push-pull motor either side. The core is the reference point for every other component in the design, acting both to focus structural borne resonance directly to earth with zero reference to the outer enclosure and also a high capacity heat sink.

“Strokes of genius are rare in any field, but I think Milnes’ Torus qualifies” – Jonathan Valin, The Absolute Sound, 2007

In the Torus, where huge amounts of low frequency energy are generated, thermal efficiency is a critical concern. In addition to the steel core, Wilson Benesch developed a Boron Nitride coil in collaboration with Oxford University. Boron Nitride offers the high electrical conductivity required by any coil design, but its thermal conductivity supersedes that of copper by several orders of magnitude.

The elegant and minimal toroidal shape of the Torus is a testament to the use of purist geometry in every component. Whether it be often earth shattering low frequencies in a home cinema, or the attack and dynamics of a drum solo, the Torus never misses a beat or fails to deliver the physical impact that we know and love of low frequency sound.
