Elements of emotion - from the deep love of pure music
The basic elements water, fire, earth, and air, symbolize both origin and progress of evolution. With this idea in mind, we want these elements to contribute to the experience of the pure pleasure of music made in Germany. Thus, we have created the four HELIX elements: Dark Blue, Esprit, Precision, and Competition. Additionally, we offer some special products in the Classic Line that have been successful for over 10 years. With all of our HELIX products we once again set the benchmark for the way you experience music and sound. In doing so, we put an emphasis on the special characteristics of music and its elementary meaning: enjoying the genuine characteristics of sound along with the many myriads of sound, tones and compositions. Our products meet the highest demands with a cost-performance ratio which is classed sensational by the technical press. With the many years of experience in developing home and car audio components, alongside with our intensive research we created new concepts of circuitry in combination with new materials. Consequently, we stick to our most important philosophy: Even in cars, acoustic signals should be reproduced as authentically and evenly as possible. True innovations and their consistent implementation in our products concept and design are necessary to achieve this goal. Numerous awards bestowed by both the German and the international technical press are proof to the outstanding quality of our products. However, even more important to us are the numerous highly satisfied customers from all over the world. They give us the incentive and the motivation to keep on making HELIX a perfect brand and, last but not least, show us that we are on the right track. Since the beginning of 2005, Audiotec Fischer has been DIN EN ISO 9001:2000 certified: a further and decisive step to guarantee the highest quality standards and to assure that HELIX products play a well-established role among car hi-fi enthusiasts.

Woven fiberglass

This long-fibered synthetic was first industrially manufactured in the middle of the 1930s. Its outstanding stiffness and its distinguished absorbing characteristics make it an interesting material for the reproduction of pure sound. Its light weight and its high density allow the creation of an exact and remarkably harmonic high-end sound. The euphony is emphasized by the materials woven structure. Fiberglass can be characterized as robust and durable because even under extreme strains it wont burst and its hardly corrosive. The fantastic and audiophile acoustic properties of the material especially evolve in connection with the specially coated Espritmembrane. Thus, the speakers eventually create an exceptionally beautiful and colorful sound.

Sisal originally comes from the Mexican highlands and was named after the harbor town Sisal on the Yucatn peninsula. The whitely fibers are gathered from the blades of the sisal plant and are first washed, dried, and pounded to release the natural fibers. Whats left is just 5 % of the original blade weight. This extract achieves the quality standard that is needed for processing our fine cones. The mechanical advantages like consistency, damping and the slight weight have direct effect on the sound of the speaker, the fundamental tone becomes richer and warmer in the end. Sisal creates a very agile and fast moving cone. Because of the high dynamics, it moreover creates an auspicious flexibility from the optimal weight of the membrane. Thereby, it reaches a very precise and clear powerfully colorful tone. This absolutely meets the requirements of advanced high audio fidelity. Audiotec Fischer attaches great importance to excellent product quality and always feels constrained to use the finest raw materials. Thus, we are proud to use sisal as an eco-friendly raw material for our products made in Germany.
