Competition Pro

The PRO Series

The COMPETITION PRO series marks the very top level of electrically and mechanically possible power handling, nowadays.
These drivers have been designed especially for long distance open show and demonstration performances at very high SPL level as well as
for the more and more popular “Pancadão” open-air stages featuring a wall of speakers, a competition trend coming from Brazil.

Competition Pro Speaker Systems

Developed for highly sophisticated sound quality requests. The Drivers of the PLUTONIUM line are available in various combinations as well as separately for individual 2-way or 3-way active applications.
The NUCLEAR line includes a wide range of speaker components available separately in pairs. This way, a lot of individual combinations are possible. More than that, GROUND ZERO offers some perfectly matching 2-way and 3-way sets for active applications.
Using outstanding materials for the cones and accurate tuning, these speakers provide an amazing sound quality performance. Apart from the separately available components, GROUND ZERO offers some models compiled to high quality passive speaker systems, as well.
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.
Each RADIOACTIVE line speaker has been developed following the market request for dynamical and high-efficient audio reproduction. Particular materials used for the mid woofers and tweeters enhance the performance especially when listening to compressed music files. Apart from that, the NEO offer a significantly reduced installation depth by using high-effective neodymium magnets.
The TITANIUM line contains the lately introduced new range of coaxial and component speaker systems with yellow color 3D-HQPP cone.
The IRIDIUM line includes a wide range of coaxial and component speaker systems in the favorable price segment including some models with a particularly low installation depth.
In addition to separately available tweeters and midrange speakers as well as subwoofers, the COMPETITION series also includes some high-tech loudspeaker systems for special applications at the highest sound and performance level.

Competition Pro Speaker Components

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.
