Helix CI5 S200FM-D2 - i5 - Shallow Woofer 200mm 2 X 2 Ohm

.

The HELIX Ci5 S200FM-D2 represents a new generation of universal speakers, the result of the innovative HELIX COMPOSE platform developed by Audiotec Fischer. Designed to overcome the technical challenges posed by the evolution of modern automotive electronics, this speaker embodies a perfect balance between high acoustic performance, universal compatibility, and intelligent engineering solutions.

Conceived according to the principle "developed in the vehicle, for the vehicle," the HELIX Ci5 S200FM-D2 combines the strengths of classic universal speakers with the typical advantages of in-car systems. The result is a 5-inch coaxial speaker distinguished by high efficiency, impressive dynamics, and sound quality capable of satisfying even the most demanding enthusiasts.

Belonging to the i5 range of the COMPOSE series, this model is positioned as the perfect meeting point between the i3 and i7 lines. It was designed for those seeking an authentic hi-fi experience, without compromising on compatibility and installation. Every detail is engineered to deliver maximum performance when combined with HELIX and MATCH amplifiers, thanks to the optimized 2-ohm impedance.

The design integrates innovative materials and proprietary technologies exclusive to the COMPOSE platform, making installation simple and versatile without sacrificing superior audio performance. The Ci5 S200FM-D2 is more than just a speaker: it is a true high-performance audio solution, designed to fit perfectly in a wide range of vehicles, delivering clear, precise, and detailed sound.

Mid-woofer and subwoofer in a single component: maximum performance even in limited space

The HELIX Ci5 S200FM-D2 is a 200 mm hybrid speaker designed to combine the best of two worlds: the precision of a mid-woofer and the power of a subwoofer. Thanks to a linear excursion of ±7.5 mm, high power handling, and high sound pressure levels, this speaker ensures deep, clean, and controlled bass reproduction even at very low frequencies.

Designed for OEM applications such as BMW under-seat storage compartments or Mercedes front bulkheads, the Ci5 S200FM-D2 delivers exceptional audio performance despite an extremely shallow installation depth of just 47 mm. The FlexMount200 mounting system allows for quick and precise integration, expanding installation options even in vehicles with limited space.

High-Tech Composite Polymer Structure: Optimal Rigidity and Absorption

All HELIX COMPOSE Series speakers (i7, i5, i3) use baskets made from a high-tech composite polymer reinforced with glass microspheres, offering superior mechanical stability with minimized resonances.

This innovative material also eliminates flux modulation in the magnetic system and provides high thermal resistance, ideal for intensive and long-lasting use. Furthermore, it allows for more compact basket dimensions, simplifying installation even in very limited spaces, without compromising performance and sound quality.

Flexible Configuration: 2 x 2 Ohm or 1 x 2 Ohm for Maximum Compatibility

The Ci5 S200FM-D2 is available in both 2 x 2 Ohm (D2) and 1 x 2 Ohm (S2) versions, offering maximum flexibility when designing your audio system.

This versatility makes it perfectly compatible with mono, stereo, or multi-channel amplifiers, allowing you to optimize the impedance based on your system configuration and always achieve maximum performance in terms of power and dynamics.

FlexMount 200 System: Universal Integration with Custom Adapters

The FlexMount 200 system is based on adapter rings specifically designed to transform a universal speaker into a perfectly compatible solution for your vehicle.

With the Ci5 S200FM-D2, OEM installation is simple and precise: thanks to the FlexMount, the speaker fits directly into the vehicle's original mounting location, ensuring a solid installation and optimized acoustics without invasive modifications. Ideal for professional installations and quality retrofits.
