Subwoofer
Concentrated amplifier power, dynamic speakers, subwoofers that really produce the goods.We want to ensure that car audio systems give maximum enjoyment and make listening to music in the car an unforgettable experience. Since its introduction, our HELIX brand has set new standards for sound excellence, technology, quality and design made in Germany. Our products meet the highest demands while offering a price-performance ratio that the specialist press - no less - has described as sensational. With our many years of experience in the development of home and car audio components, and the creation of new circuitry concepts combined with innovative materials, we have remained true to our belief that - even in the car - acoustic signals should be reproduced as authentically as possible. For this to be possible, true innovations are necessary. Once proven, these are effectively implemented in the conception and design of our products. Numerous awards conferred by the national and international trade press, plus satisfied customers around the world are ample proof of the universal confidence that our products enjoy. Such plaudits confirm the viability of the development direction that we have adopted. And they motivate us to bring ever more perfection to the HELIX brand. With the beginning of 2005 we have established DIN EN ISO 9001:2000, a further decisive step to highest quality and to ensure that our products continue to occupy a permanent place in the hearts and minds of car hifi enthusiasts the world over.

Power Caps

HELIX Power Caps made in Germany. The optimum power supply system for your amplifiers HELIX Power Stabilizers supply amplifiers at full power through stabilisation of the vehicle supply network. Voltage fluctuations caused by extreme load peaks (deep bass notes) are compensated out through the use of HELIX Smart Power Caps. The amplifier always receives enough energy in order to modulate to maximum output. The result: Crisp basses and an impressive all-round sound. Thanks to the use of high-quality components, for example electrolytic capacitors specifically designed for car audio requirements with their multi-contact and ultrasonic cold-welded wound foil assemblies, the power caps are able to offer an extremely low, frequencyindependent internal resistance. HELIX Smart Power Caps are of a vibration-protected design. Protection against overvoltage and wrong polarity of the DPC 1000 ensure that installation is both simple and safe. It also features an integrated digital voltage display.

X-just Active Crossover

Set Up System
Expensive measurement equipments and extensive work to set up the exact frequencies of active crossovers belong to the past. The HELIX X-just from AUDIOTEC FISCHER is a newly designed and innovative measurement instrument that saves a lot of time and efforts. q Potentiometer tolerances that normally complicate the adjustment are irrelevant when using the X-just. q The integrated sinus generator (frequency range 20-20000 Hz) makes the exact set-up of any desired frequency possible. The HELIX X-just can also be used to burn in loudspeakers.

HELIX goes High End: The new component systems of the COMPETITION series were consequently designed for excellent and natural sound reproduction to create audiophile speaker systems at an extraordinary price/performance ratio. To meet the high COMPETITION quality standards, each speaker is handcrafted and thoroughly inspected. The construction of the passive crossover is also uncompromising: the expensive-looking black circuit board is embedded between a black base plate and a clear plexiglass panel, air coils and foil capacitors produce clean and contoured mid-basses as well as pleasing but powerful general sound characteristics.
