ULTRA speakers are designed for the most demanding music lover.

Carefully built by hand with the best materials and selected in pairs, they are delivered in fine wooden boxes.

The mid-bass driver ULTRA K-165 uses a high-tech fabric cone “Made in Germany” in conjunction with linear suspension and a narrow-tolerance copper voice coil with a linearized NEO motor. Built in a filigree aluminum basket for optimal air flow, these are the ingredients for outstanding neutrality and sound quality.

The tweeter ULTRA T-30 with its 30mm coated silk dome is characterized by a particularly low resonance frequency and extreme neutrality. The linearized NEO magnet system with the complex rear ventilation of the cone in the solid aluminum housing enables the wonderfully spatial and precise audio reproduction with an extremely wide frequency range.

REFERENCE speakers are designed for demanding high-end music lovers. Accurately hand built in Europe, selected in corresponding pairs and delivered in classy wooden boxes. Midbass and midrange speakers are made from hand-coated, pressed paper cones and hand-spooled copper voice coils, inserted into manually machined aluminum parts of the basket, forming the basis for outstanding high-end sound quality. The tweeter features a particularly low resonance frequency. The usable wide frequency range of the hand-coated silk dome thus enables astonishingly spatial and precise audio reproduction.

In order to compile an individual sound quality setup at highest level, the speakers of the PLUTONIUM line are available in pairs as components separately.
In order to compile an individual sound quality setup, the speakers of the NUCLEAR line are available in pairs as components separately.
Using outstanding materials for the cones and accurate tuning, these speakers provide an amazing sound quality performance. The drivers are available for active setups, separately.
For some years customers were missing matching loudspeaker components and systems belonging to the GROUND ZERO HYDROGEN series to be combined with its amplifiers and subwoofers. Based on a particularly designed aluminum cast basket the engineers have realized a powerful 6.5” midwoofer with a strong ferrite motor and oversized CCA voice coil. In combination with a vented silk dome tweeter equipped with a coupled chamber and a passive crossover, the new HYDROGEN series 2-way system is born for customers looking for an extraordinary performance. The loudspeakers are available separately for active setups, as well.
Some components of the RADIOACTIVE loudspeaker systems are also available separately.
The TITANIUM line includes a wide range of coaxial and component speaker systems in the favorable price segment and a separately available tweeter.
The IRIDIUM line includes a wide range of coaxial and component speaker systems in the favorable price segment and a separately available tweeter.
For high-frequency and mid-range reproduction, the COMPETITION series offers a variety of high-efficient far-field compression tweeters and various midrange speakers. The latter can be used in free-air applications as well as in horn or bass reflex systems.
Speaker components of the COMPETITION PRO series are specially designed for a long distance to the listener and are particularly suitable for show and demonstration purposes with high sound pressure levels.
