“Quirky cool design from Denmark”

SKU JER-12 Category

Loudspeakers are a part of our homes just like any other piece of furniture or art, and to most people it is important to have a beautiful and stylish home.

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.

Behind JERN® is a company called Dansk Skalform, which is actually a casting company. 

Traditionally, they have made an unlimited number of differing components, predominantly for the car and machine business sectors.

The company was founded in 1975 by the diploma engineer Holger Dissing and today it is still family run by the Søren Dissing and Peter Dissing.

Curiosity has always driven this Danish company and one day Søren Dissing, stopped and thought to himself: What would happen if a loudspeaker was moulded out of one solid piece of iron? So Søren and his team of engineers started working on a prototype for a loudspeaker. 

The criteria was that every single piece should be of the finest quality. As they say in Danish, nowhere did the team jump the fence at the lowest point in the making of the JERN loudspeaker.

Finally a new and revolutionary compact speaker was created, showcasing clean sounds accompanied by a beautiful organic shaped design.

Jern use a special grade grey cast Iron (called Vibrakill ®), with a very high amount of Graphite (Carbon) mixed in the Iron.The Graphite dampens our cabinets vibrations 100 times better than Aluminium, and much better than MDF and wood.

Iron is also much stronger and heavier which also reduces cabinet vibrations, so you mainly hear the good sound from the loudspeaker drivers.

The making of the loudspeaker at a casting company added a brand new raw factor and authenticity to the world of sound.

The detailed surface of each speaker is unique to that single speaker. Just like fingerprints – they look similar but in detail there is no other.

Some might ask themselves – What would a moulding company know about sound, and why would I choose them over a traditional wooden or MDF box

Well, to those in doubt we suggest you listen to Jern speakers, and decide for yourself.

We keep the JERN 12WP which is our favourite speaker from the Jern range as it does not need an additional subwoofer.

This makes it ideal for most situations and due to its unique design can also be placed close to a wall.

We also supply the JERN with a cork mat – just in case you need to protect your furniture further (the rubber ring can mark some types of furniture will rubber residue).

Specifications – 12WP:

Design: Two way. Phase linear wide dispersion design. Sealed cabinet for best transient response.

Drive units: Unique Wavecor woofer 5 3/4 inch 146 mm frame.

Excellent midrange performance due to a new woven and optimised glass fibre cone design.

  • Tweeter SEAS 19 mm. Wide dispersion. Low distortion due to long excursion. Textile membrane.
  • Rigid steel chassis with extensive venting for lower air flow speed reducing audible distortion
  • Vented centre pole with dual flares for reduced noise level at large cone excursions
  • Heavy-duty fibreglass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
  • Large motor structure for better control and power handling
  • Built-in aluminium field-stabilising ring for reduced distortion at high levels
  • Low-loss suspension (high Qm) for better reproduction of details and dynamics
  • Black plated motor parts for better heat transfer to the surrounding air
  • Conex spider for better durability under extreme conditions
  • Gold plated terminals to ensure long-term trouble free connection
  • Delivered with foam gasket attached for hassle-free mounting and secure cabinet sealing

Dimensions: 30 cm tall, 19,5 cm deep and 21 cm wide.

Comments: These loudspeakers are developed to work really well close to walls

Finishes:

  • White
  • Black
  • Grey

Options:

Tripod table-top stand in oak or walnut (£175.00) or cast iron traditional stand (£550.00).

Jern 12 range:

Jern 12 WP – as above (£1500.00)

Jern 12 XF NYHED – Lower resistance in coil to damp treble (£1850.00)

Jern 12 WS – with a lower resistance crossover coil, sheeps wool damping inside, and vibration resistant braided screened silver coated copper cables.  ScanSpeak 20mm tweeter. The tweeter frame is damped by a 3 mm thick sheep wool felt disc with a star shaped cutout for the dome. This disc also reduces the sound waves traveling out from the dome on the tweeter surface to the edge, and thus makes frequency response smoother. (£2250.00)
