JERN15 - “What a profound and present bass for such small speakers."

On the 8th and 9th october the Benelux/German distributor Daluso presented JERN at the Dutch Audio Event 2022. This year no 100.000 Euro full Reimyo/Harmonix setup. As kind of an experiment, the JERN 15 loudspeakers were playing, during an ongoing demo, in a simple setup with a 15 year old Auranote amplifier/cd-player/FM-radio all-in-one combo. Nothing special one would say. However, it was Daluso’s choice to perform a very approachable demo for demanding people who simply want to listen and enjoy music. Not for audiofools being gaspingly obsessed by Hi-Fi or High-End. The 30 square meters room was tuned with 'Harmonix Room Tuning Devices’ and electrosmog controlled by several Vortex HiFi Optimizers and some Hijiri HPC-cabling. Only (XR)CD’s were used as music software. On display were JERN 11, 12WS, 14EH and the W8, together with ISOL-8 and Vortex HiFi. The room was very modest and home-like decorated. “Daluso always want to impress by a beautiful sound, not by a beautiful presentation”. Many people felt very comfortable sitting and walking around in the room, watching and listening in a relax way. What were the attendies comments during the show: "What a sound stage" - “What a profound and present bass for such small speakers" - “Really impressive" - “Amazing” - “Very ... very musical" - "finally I am listening music at a show” - “Best I heard so far”. More than 40 people asked, “where is the subwoofer?” "You hear what you see, no sub” was Daluso’s answer. More than 80 people did an attempt in lifting a JERN 12WS and were amazed of its weight. “That's Cast Iron!”. Many surprised, pleasantly shocked, enthousiastic and happy smiling faces left the room. On Sunday, a show reporter of the British magazine ’The EAR’ moved slowly into the room. After listening a few tracks he said "what an amazing sound". Which JERN’s are playing? … I reviewed a pair of JERN speakers some time ago. This is really amazing, in such a small and simple setup.” According to Ed Doggen of Daluso both days at the Dutch Audio Event 2022, presenting JERN to the Dutch and Belgium consumer market were really very succesfull.

…the Jern 15 loudspeaker is an improvement on an already strong range…

…without subwoofers, the Jern 15 loudspeakers are hugely capable and retain their presence and razor-sharp resolution.

Die dänischen Kompaktlautsprecher JERN 15 verblüffen mit ungewöhnlichem Design und erstaunlichem Klang.

High End ist mit der JERN in der kleinsten Hütte möglich, und dazu ist sie auch noch unverschämt gutaussehend und perfekt verarbeitet. Die JERN 15 ist eine Alternative, die in jedes Auswahlportfolio bei der Ausstattung kleinerer Räume gehört.

I love the Danish cast iron box small speaker JERN 15, which I have used for more than a year, and introduce its background, characteristics, sound and collocation.

It is a true high-end speaker in a small, and attractive, package.

A well-balanced speaker that presents a lovely neutral rendition of music.


Enjoy the
