Description

JERN14 DS Loudspeaker
The JERN®14 was developed to work with high-quality subwoofers.

Therefore it is -6dB at 90 Hz. Our JERN®12 can be used without a subwoofer.

Due to less bass demanded from the woofer, the JERN®14 can play louder with less distortion than the JERN®12.

The JERN®14 is the new revolutionary compact speaker from JERN®. It is elegant and small, but it delivers High-End audio quality. The keys to its performance are its shape, components, and choice of materials.
JERN® is not a mass producer of loudspeakers. Each speaker remains essentially hand-built by people with decades of experience at their fingertips.

The name JERN®
Speakers 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®14 differs from other high-end speakers because the choice of material and casting method allows our designers and engineers to create new shapes, that improve the performance compared to regular square boxes, which compromises the sound quality.
The detailed surface of each speaker is unique to that single speaker. It is just like fingerprints; they look similar but in detail, there is no other just like yours.

A new generation
The iron for the cabinet is refined from recycled materials and it is good for a lifespan of more than a century.

Sound quality is an assessment of accuracy and enjoyability. Loudspeaker sound is all about transferring the sound waves from the loudspeaker drivers to you and reducing disturbing vibrations and noises from the cabinet. Different materials give different vibration levels. Traditionally, loudspeakers are made from wood because of its low cost and ability to reduce vibrations.

JERN® aims for the perfect sound. This is the cornerstone in our design, components, choice of materials and production.

The JERN®12, JERN®14 and JERN® w8000 loudspeakers are made from our vibration absorbing grey cast Iron, which reduces vibrations up to 100 times better than Aluminium. Our cabinets are also much better than MDF and wood. This Iron is our key to the clear and clean sound, which the JERN® loudspeakers deliver.

Technology

• Cast Dome Structure (CDS)
  CDS is a surface of small domes on the inside of the speaker cabinet. The cast cone surface subdues and spreads standing sound waves that are the key to providing a complete acoustically neutral cabinet.
• One Piece Cabinet (OPC)
  Our OPC sand-cast technology makes it possible to create the entire cabinet in one durable structure, which allows a solid mounting of the speaker unit, which contributes to a vibration-free cabinet and a much longer lifespan of the speaker.
• Unique Fingerprint Surface (UFS)
  Each of our speakers has a unique surface. It is uniquely created when the iron flows into the mold. The unique patterns are just like fingerprints which means that there are never two speakers that are exactly the same.
  Finally, the cabinet gets a high-quality powder coating.
• Low resonance material (LRM)
  LRM is our technology flagship and one of the most important factors when it comes to reducing vibrations within the cabinet.
