The Technique

Hornspeakers

Our speaker systems are subject to the constant pursuit of perfection - so inevitably horn systems are used in the development.

Unachieved Dynamics

No loudspeaker concept is faster and at the same time more dynamic than horn systems.

Maximum efficiency

Our horn systems all have such high efficiency that even tube amplifiers with the lowest power come into their own.

Universal & contemporary

Together with our DSP Systemamps a complete all-in-one solution without compromise.

Best Hardware

All our drivers are either specifically made for us or carefully selected with an eye on what is technically feasible.

Naural Sound

The consistent use of solid wood reduces sound coloration caused by cabinet resonance to an absolute minimum.

  • BEST MATERIALS - ARTISANAL CRAFTSMANSHIP

01

Modern & timeless Design

Anyone can do simple.

Our loudspeakers are planned and developed using the latest software.
The production is done where necessary with high-precision CNC milling under the lowest tolerances.

Anyone can do plastic.

Our loudspeakers and horns are consistently manufactured in solid wood to the highest standards.
Sound colorations due to cabinet resonances are reduced to an absolute minimum.

You can hear that!
02

Made in Germany - everything in house


The complete scientific development as well as the technically demanding production has always been carried out under one roof. Of course, this always presents us with great challenges, but offers at least as much freedom for alternative thinking and promotes innovative approaches.
All in all, this approach allows us to guarantee you a consistently high quality of the end product - right from the very first step.
