The entry into the HELIX sound world

Enter the HELIX sound world with our PURE F speaker series. The powerful F-Series gets the maximum power out of your amplifier thanks to its 3 Ohms technology. In combination with the exceptional sound performance with powerful bass, clear mids and detailed highs, an exciting sound experience is bound to occur.

Easiest integration at its best!

The best sound isn’t any good if the installation causes trouble.
The PURE F loudspeakers demonstrate with their well-thought-out design in every detail, how it is done the right way. This starts with the low installation depth of the drivers, which considers the increasingly limited space in modern vehicles. In addition, the system offers an extensive range of installation accessories with an innovative bayonet lock for the extremely compact tweeter, which allows any installation option you can imagine, up to simplifications in the wiring thanks to our "Flex-Crossover" design.

Maximum flexibility – the "Flex-Crossover”

The sophisticated, two-part and immensely space-saving "Flex-Crossover" maximizes installation flexibility, for example when the tweeter is positioned in the A-pillar and the woofer in the door. This offers decisive advantages, especially in space-critical installations. In addition, the tweeter crossover is equipped with a two-stage level adjustment, which allows adaptation to both personal listening taste and the installation situation.

Cool design – noble materials

The timeless and stylish design of the F loudspeaker series with the dynamic Space-Line styling of the woofer cone is by no means an end in itself, but rather the result of the use of high-quality materials. The carbon fibres embedded in the polypropylene cone of the woofer optimize the midrange reproduction, whereas the coated silk dome of the tweeter guarantees exceptionally airy highs.
