"Perhaps the most important instrument of the 20th century is not the guitar, the synthesizer or something similar, but the loudspeaker."

 Brian Eno - The German Frankfurter Allgemeine newspaper

The Coax Series loudspeakers play any musical piece with incredible precision and speed. The simultaneous transfer of all high and midrange frequencies ensures a clear, natural and perfect sound.


Over the years we have been honoured to receive many awards, prizes, certificates, medals, trophies and cups for our products. Receiving all this recognition and the constant confirmation of our work have been a tremendous encouragement.

A centre loudspeaker for home cinema systems that meets the highest requirements


The Coax Series is handcrafted and produced with maximum precision. None of our loudspeakers leave our production before being tested and adjusted. The current Coax Series, which includes the Coax 311 bookshelf loudspeaker as well as the two Coax 511 and Coax 711 floorstands with heights of well over one meter, represents already the second generation of the Coax loudspeakers. The trio offers cabinets made from extruded aluminium, which provides the loudspeaker not only with a stylish and elegant look but also offers outstanding stability. In this way we ensure that power is not lost through vibrating cabinet walls.

The latest Coax Series features the Tension Improve Module (TIM) perfected by PIEGA. These modules keep the entire cabinet under a controlled tension, thus suppressing even the smallest cabinet vibrations. Any residual micro resonances are completely eliminated with new visco-elastic damping foils.

COAX 511
The slim floor-standing loudspeaker with a coaxial midrange tweeter and powerful bass is perfect for medium-sized rooms.


In all essential points, our second generation Coax systems are a further development of the previously used drivers. The ingenious basic operating principle of the annular midrange ribbon was enhanced through the use of stronger neodymium magnets and pole plates made from high tensile steel. This enables a higher degree of efficiency to be achieved. The layout of the flat coils underneath the foil membrane and the damping of the foil membranes were also optimized. The new UHQD subwoofers come with titanium oscillating coil mounts, a new suspension system, and specially shaped and coated aluminium membranes that are extremely rigid. The standing loudspeakers provide these as passive radiators.
