Helix Ci3 K200.2FM-S3 MK2

Helix Ci3 K200.2FM-S3 MK2 – 8″ 2-way FlexMount component system, 3 Ω

The Ci3 K200.2FM-S3 MK2 is a 200 mm 2-way component set from the HELIX COMPOSE i3 line, part of the HELIX COMPOSE platform, a reworked generation of universal speakers that Audiotec Fischer develops in the vehicle for the vehicle, aiming to merge the flexibility of a universal speaker with the fit advantages of vehicle-specific systems. It is designed for easy fitting in cars and to pair with HELIX and MATCH amplifiers, with an emphasis on safe connection and operation.

Its 3 Ω design increases efficiency and sound pressure on HELIX and MATCH amplifiers, reaching 94 dB at 2.83 V. The 200 mm woofer uses a Cenosphere-coated paper cone in a glass-bead-reinforced polymer basket and comes with a universal mounting ring and grille; the 20 mm tweeter pairs a black aluminium dome with a neodymium magnet. FlexMount200 and FlexMount20 adaptors, COMPOSE Connect / ProConnect and WireKit compatibility support vehicle-specific installation.

Drivers & Construction

• Tweeter: 20 mm (0.75″) black aluminium dome, neodymium magnet, 20 mm voice coil, ultra-compact, FlexMount20 compatible
• Woofer: Paper cone with Cenosphere coating – hollow microspheres embedded in a polyamide layer raise stiffness and internal damping while keeping the cone light; polyurethane dustcap; 25 mm voice coil (11.6 mm winding height); ProConnect terminal; FlexMount200 compatible; universal mounting ring and grille
• Basket: Polymer composite basket reinforced with glass beads – rigid, low in self-resonance, reduces flux modulation of the magnet system, heat-resistant and compact for tight mounting spaces
• System: 2 tweeters, 2 woofers and 2 separate crossovers form the stereo set
