Cast Iron speakers

"Redefining just what is capable from a compact speaker, the JERN range of loudspeakers are unlike anything you've seen, and believe us, HEARD".

Frank Prowse Hi-Fi

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.

…the Jern 15 loudspeaker is an improvement on an already strong range…

…without subwoofers, the Jern 15 loudspeakers are hugely capable and retain their presence and razor-sharp resolution.

Die dänischen Kompaktlautsprecher JERN 15 verblüffen mit ungewöhnlichem Design und erstaunlichem Klang.

High End ist mit der JERN in der kleinsten Hütte möglich, und dazu ist sie auch noch unverschämt gutaussehend und perfekt verarbeitet. Die JERN 15 ist eine Alternative, die in jedes Auswahlportfolio bei der Ausstattung kleinerer Räume gehört.

Rubberbase for compact speaker

The JERN Rubber Base is a simple, yet clever addition to a normal speaker stand. It allows the JERN 12, 14, and 15 cabinets to tilt in the direction or angle you need.
It also reduce vibrations, so you can place the JERN loudspeakers on furniture.
