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 to contribute these elements to experience the pure 

pleasure of music. From this result we have created the four 

HELIX elements: Dark Blue, Esprit, Precision, and Competition. 

With the new 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 stuck 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 and, even more importantly, 

with highly satisfied customers from all over the world, is 

proof to the outstanding confidence in our products. It shows 

us that we are on the right track, which gives us the incentive 

and motivation to keep on making HELIX a perfect brand. 

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.

Subwoofer 

The exclusivity of the Esprit line is basically emphasized by the extraordinary optics of the woofers. Their flat membrane 

made out of woven fiberglass creates a very powerful but also exact bass, harmonizing perfectly with the other components 

of this line. The membrane and woofers are slim in design, this makes the mounting depth amazingly small. 

Additionally, with excellent manufacturing and high quality materials, this guarantees long-lasting and high class listening 

pleasure. The digital mono amplifier E10, is the perfect compliment for driving these woofers in an ideal and steady way, of 

course naturally on a high end level.

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 material’s woven structure. 

Fiberglass can be characterized as robust and durable because even 

under extreme strains in won’t burst and it’s 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.

Amplifier 

Thanks to the computer controlled, analog technology with MosFet-drivers and bipolar power transistors in TO3 housing the 

flat amplifiers P 200 and P 400 are extremly powerful and efficient. Bridged, the P 200 (700 Watts RMS) plays optimal with the 

P-woofers during the P 400 as a 2/3/4-channel amplifier which fits in ideally with the classic “made in Germany“-speakers of 

the “Precision”-line. 

Concerning power and the acoustic design, this generation of amplifiers has gained a lot. High end fans and enthusiasts who 

require advanced music components will be stunned and amazed of such brilliant quality.

Component systems 

The new component systems of the Precision-line possess a sensational sisal-membrane which was especially developed 

for HELIX. An unbelievably, clear and precise picture of sound despite the highest power requirements shows explicit quality 

of why it is made in Germany. 

The high-graded crossover with its gold-plated jumpers allows perfect adjustment of the speakers to the vehicle acoustics. 

They also give you the choice of a 2 or 4 Ohms mode, which allows the operation of one or two bass speakers per channel. 

The preciseness of these speakers is of outstanding quality. This sets the benchmark for high end enjoyment in cars.

Sisal 

Sisal originally comes from the Mexican highlands and was named 

after the harbor town Sisal on the Yucatán peninsula. 

The off white fibers are gathered from the blades of the sisal plant 

and are first washed, dried, and pounded to release the natural fibers. 

What’s left is just 5 % of the original blade weight achieving the quality 

standard that is used 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. 

Coincidently this creates a very agile and fast moving cone. Because 

of the high dynamics, this creates an auspicious flexibility from the 

optimal weight of the membrane. 

Thereby it reaches a very precise and clear powerfully colorful tone. 

This meets the requirements of advanced high audio fidelity absolutely. 

A great deal of pride is placed on the excellent quality of the 

eco-friendly raw material, ultimately ”made in Germany“ is paramount 

for this faultless accomplishment.
