Pistonik

Low-frequency drive unit motor system

Flawless Force

Our unique Pistonik motor system is the driving force behind Linn-designed low frequency drive units. Pistonik produces flawless linear force over its entire wide range of in-and-out travel—even when driven extremely hard with bass-heavy music—thanks to a very long-stroke motor topology with a specially extended magnet gap. Major innovations throughout Pistonik’s design engineer out magnetic, mechanical, and thermal factors which together conspire to defeat linear performance.

Eliminates Magnetic Drag

To stabilise the magnetic field inside the voice coil gap, and reduce the impact of eddy currents, we’ve immersed the whole Pistonik motor assembly in permanent magnetic saturation. This enhanced stability reduces distortion drastically, providing the drive unit with exceptional speed, agility and responsiveness by lowering magnetic drag.

Eliminates Acoustic Compression

Pistonik’s triple-layered ventilation network eliminates acoustic compression as a source of distortion and noise, allowing air to move freely and silently through the motor structure. This ensures the moving mass of Pistonik-equipped drivers maintains smooth, supple motion, with the absolute absence of audible air turbulence.

Eliminates Thermal Buildup

Untroubled by rising resistance due to thermal buildup, Pistonik’s performance remains steadfast after hours and hours of non-stop listening. The voice coil is kept cool by carefully designed ventilation paths; heat is drawn directly into the surrounding steel and aluminium structures, so that warm air is continuously exchanged for cool within the speaker cabinet.

Pistonik in Action

Our unique Pistonik motor system forms the core of the first-ever Linn-designed drive units – a 6" upper bass and 8" woofer. With it, these drivers achieve ultimate linearity across a prodigious excursion range, with dramatically lower distortion and greater accuracy than anything available elsewhere.
