JERN w9000 is a new compact on-wall loudspeaker from JERN cast in Iron. It has a complete round shape for a discreet design. It fits in everywhere – either as an on-wall installation or mounted in the ceiling. A bracket for on-wall installation is included. A strong screw and wall is needed.
The speaker comes with either white or black cloth, which covers front of the cabinet. There is also an instruction for how to customize your own cloth in every fabric to either suits in with the existing interior, or gives the possibility to play with colors in every way you like. A perfect solution for yourself, or your favorite installer.
Cloth colours currently available are white and black.The cast cabinet is available in Nordic Black, Polar White, Casting Grey and Fine Red.
The tweeter is a 22 mm diameter, this gives wider dispersion of high frequencies off axis than 25 mm.
It has a special developed 5 1/4 ” woofer, that makes good bass in a 5 liter closed cabinet.
The bass is -6dB at 60 Hz, and when placed on a wall in a normal room, it will give bass down to 40 Hz .
This happens because the room gain increase the deep bass, and the w9000 is a closed cabinet, which only reduce the deep bass by 12 db per octave.
Bass reflex cabinets reduce bass by 24 dB per octave, so they benefit less well from room gain.
In Danish, JERN means IRON which refers to the cabinet material.
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 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 instead of regular square boxes that compromises the sound quality.
A new generation
The iron for the cabinet is made from recycled materials and is good for a lifespan of more than a century.
For the best sound quality, you should only hear the soundwaves from the loudspeaker drivers. So we want to reduce disturbing vibrations and noise from the cabinet. Different cabinet materials give different vibration levels.
Traditionally, speakers are made from wood because of its low weight and ability to reduce vibrations. JERN focuses on the perfect sound which is the cornerstone in our production, design, components and choice of materials. JERN w9000 speakers are made from strong and heavy cast iron that reduce vibrations much better than conventional wood. This is our key component to the crisp clean sound JERN loudspeakers delivers.
