JERN cabinets are made as a one-piece composite metal structure of proprietary material called ‘’ Vibrakill ‘’.
This material ensures massive stability and density, providing unsurpassed resistance to vibrations and resonance.
Each iron enclosure has a unique cast fingerprint and delivers utterly silent and distortion-free sound, unlike any other speaker on the market.

JERN® differs from other high end speakers because the choice of material and casting method allows their designers and engineers to create new shapes that improve the performance instead of regular square boxes that compromise on sound quality.
JERN®is not a mass producer of speakers. Each speaker remains essentially hand-built by craftsmen with decades of experience at their fingertips.
The name Jern literally translates from its native Danish as ‘iron’ and the origins of this loudspeaker are far from the usual method of speaker cabinet design.
