JERN MODEL 11 BLACK/BLACK GRILLE *
The JERN Model 11 is an elegant design, and it delivers an audio quality like no other small loudspeaker. Its shape, the selected components and the extraordinary cabinet material are the keys to the superior sound quality.
Danish design Casting in iron allows our designers and engineers to create this new, rounded and organic shape. The shape and the strong heavy material both increase the sound quality. JERN is the Danish word for iron
The best cabinet shape The spherical shape gives the smoothest frequency response, and the lowest amount of diffraction sounds disturbing the music. This has been known for many years, see page 23 of PhD Harry F. Olsons book “Elements of Acoustical Engineering” from 1957 in our 8 page brochure.
Therefore the cabinet is shaped like 2 spheres melted together. The cabinet is 30 cm tall, 19,5 cm deep and 21 cm wide.
An easy load for your amplifier The nominal impedance of 4 ohms makes the JERN 11, 12XF and 12WS an uncomplicated load for good amplifiers. The sensitivity is 86 dB (2,83V 1m).
Cabinet advantages The closed cabinet means that there is no annoying bass reflex resonance or noise from the port. The impulse response is faster. The bass is better defined.
Optimum placement for the small listening room The JERN Model 11 are optimized for a close to the wall loudspeaker placement. The closed cabinet has only 12 dB per octave reduction below 65 Hz. The normal room gain bass increase means that it is possible to get good bass down below 40 Hz.
Sustainability The cast iron cabinet has a lifespan of more than 100 years and it is made of recycled material, except for the color paint. The JERN11 and 12 are elegant loudspeakers with revolutionary technology. They offer you a unique, musical sound experience!
Optional rubber mounting rings available separately for all Jern Model 11 loudspeakers.
