HELIX CI7 W165FM-S3 Pair of 165mm woofers - 3 Ohm


The HELIX COMPOSE i7 series guarantees an exceptional sound experience in the car. The i7 speaker series is completely manufactured in Germany and optimized for uncompromising musical pleasure. All speaker impedances are perfectly matched to combination with HELIX amplifiers, always guaranteeing maximum performance. HELIX COMPOSE stands for intelligent engineering and consequently implements high-efficiency 3 Ohm technology, which harmonizes perfectly with all HELIX amplifiers and at the same time enables a clearly perceptible advantage in terms of efficiency and maximum sound pressure. Thanks to the notable influence of sister brand BRAX and the uncompromising high-end philosophy, only the highest quality components are used in the i7 series, such as the hand-crafted UHD (Ultra High Damping) paper cone. Manufactured with a particularly complex process, this cone guarantees optimal frequency response and the best possible impulse response, for incomparable musical pleasure.

All HELIX COMPOSE i7 and i3 speaker baskets are made of a high-tech composite polymer, further reinforced with glass beads. The result: maximum stability, minimal self-resonance, elimination of magnetic system flow modulation and maximum resistance to thermal influences. Last but not least, this allows for much more compact basket dimensions and thus simplifies installation in tight space conditions. The innovative ProConnect terminal is a professional automotive connector that allows the safe use of conventional speaker cables, offering maximum flexibility in audio system upgrade design. In addition, the connection is interlocked, offers protection against polarity reversal and is electrically and mechanically very robust. WireKits allow HELIX COMPOSE components to be connected to the original wiring or, optionally, to the crossover, in the most convenient way. Manufactured according to high automotive industry standards, these stoppable adapter cables meet all requirements of the challenging environmental conditions that installers face every day in vehicles.
