A DIN ISO 9001 and ISO 14001 certified company, it now delivers its award-winning brands Brax, Helix and Match to more than fifty countries worldwide. To Audiotec Fischer the label "Made in Germany" has always been more than just a designation of origin; it's a promise of quality that everyone at the Schmallenberg site remains committed to. Audiotec Fischer has more than thirty years of experience in the development and manufacture of high-end car and home audio products. From the initial brief through to the finished product; all components are assembled in-house with the sole aim of reproducing acoustic signals as authentically as possible whilst optimizing the sound experience ever further.

i7 Series - Making Better Sound All The More Easier
The i7 series represents a range of uncompromising high-end components to provide an outstanding sound experience in your automobile. With obvious influence of the high-end sister brand Brax, the i7 speaker series is completely made in Germany and optimized for uncompromising music enjoyment. Part of the Compose range and available in either component set or coaxial configuration; the i7 represent the epitome of aftermarket upgrade speakers and are compatible with all Helix Compose technologies such as FlexMount, FlexConnect, ProConnect and WireKits. These systems allows the speakers to fit into a multitude of applications across many vehicles.

Design Ideologies
The Compose range was conceived due to the increasingly demanding challenges of modern automobile technology, not to mention Helix’s unending pursuit of intelligent solutions. Helix took its universal speaker ranges and undertook an extensive redesign. The result is this innovative series, which aptly stands by the motto developed inside the vehicle, for the vehicle. The various Compose series’ combine classic universal speakers with the advantages of vehicle-specific systems by marrying innovative materials and the latest technologies with smart, practical engineering solutions. The pinnacle of the Compose stable are the i7 range of components. They represent the best of all spheres in harmony; high efficiency, fantastic sound quality and enormous dynamics that fit in any vehicle.

High-End Equipment Made In Germany
The i7 series represents an uncompromising high-end approach for an outstanding sound experience within your automobile. With obvious influence of the high-end sister brand Brax, the i7 speakers are completely made in Germany and optimized for uncompromising musical enjoyment. All speaker impedances are perfectly matched for the combination with modern amplifiers, guaranteeing maximum performance at any time. In addition, Compose introduces four new mechanical technologies that offer unbeatable practical benefits.

Impressive Efficiency
The i7 components are intelligently engineered, thus implement highly efficient impedance technology. This allows them to perfectly harmonise with most modern amplifiers whilst at the same time allowing a clearly perceptible boost in efficiency for maximum sound pressure.

High-End Coaxial Coincident Speaker
This unique coaxial speaker combines the best of the Ci7 high-end midbass driver and the Ci7 high-end tweeter. Due to its complex design, this driver is not just a simple coaxial speaker but a true coincident driver. This provides the advantage that the sound from both drivers is produced at exactly the same time, turning the speaker into a point-source. This results in extremely precise and time-coherent sound reproduction, which is particularly advantageous in acoustically challenging environments. The alignment of the drivers along the same sound axis ensures optimal phase coherence and a consistent sound image. This makes them a most versatile solution for audiophiles who want to experience a coherent sound stage from a single speaker position, while still benefiting from the intelligence and integration-friendly design of the Compose ideology.

Brilliant Treble Response
The i7 tweeter is equipped with a fine-meshed silk dome with visco-elastic Acronal coating on both sides. This guarantees a brilliant and smooth treble response. In addition to this, the integration of pure lamb’s wool dampened chamber enables a very low resonance frequency and allows a deep acoustic coupling.

Ultra High Damped Crafted Paper Cone
The i7 series feature proprietary handmade ultrahigh damping (UHD) paper cones, manufactured in a particularly complex process. This cone guarantees an optimal frequency dispersion as well as the best possible impulse response for incomparable musical enjoyment.

High-Tech Polymer Basket
All i7 baskets are made of a high-tech polymer composite, which has been additionally reinforced with glass spheres. The result is maximum stability with minimal self-resonance, while also eliminating flux modulation of the magnetic system and maximum resistance to thermal influences. This allows for more compact basket dimensions and thus simplified installations into cramped installation conditions.

FlexMount – Universal Meets Car Specific
FlexMount is a mounting system based on specially developed adapter rings, allowing the installation of all Compose speakers into an almost infinite number of vehicles. Thus the universal loudspeaker effortlessly becomes a vehicle-specific loudspeaker, that can be easily installed in the original installation position of the vehicle in an acoustically optimized way with the matching FlexMount adapter ring.

ProConnect – The New Industry Standard
Helix’s innovative ProConnect terminal is the new industry standard. A professional automotive connector allowing the safe use of conventional speaker cables while also being ideally designed for connection via flat plug with Helix WireKits. This offers maximum flexibility in the design of the sound system upgrade. Furthermore the connection is interlocked, preventing reversing the polarity.

WireKits – Plug And Play At Its Best
Helix WireKits allow the connection of all Compose components to the original wiring harness, or optionally to the crossover; in the most comfortable way. Manufactured according to the high standards of the automotive industry these arrestable adapter cables meet all requirements for the harsh environmental conditions that installers are facing in vehicles every day.
