JERN 12 WP

Overview

The JERN®12 WP was developed to work without a subwoofer in small rooms close to the walls.

For even deeper bass, a subwoofer can be added below 65 Hz.

The JERN®12 is the new revolutionary compact speaker from JERN®. It is delicate and discreet but it delivers High End audio quality. The key to its performance is all in its design, components and choice of materials.
JERN®is not a mass producer of speakers. Each speaker remains essentially hand built by craftsmen with decades of experience at their fingertips.

Design

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®12 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.

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.
