Helix Ci3 C130.2-S3 MK2

Helix Ci3 C130.2-S3 MK2 – 5.25″ 2-way coaxial speaker, 3 Ω

The Ci3 C130.2-S3 MK2 is a 130 mm 2-way coaxial speaker 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 fits easily into cars, works well with HELIX and MATCH amplifiers and puts emphasis on safe connection and operation.

With its 3 Ω design it offers better efficiency and higher maximum sound pressure. The Cenosphere-coated paper cone sits in a glass-bead-reinforced polymer basket driven by a powerful magnet system, while the coaxial 20 mm tweeter combines a black aluminium dome with a neodymium magnet. The ProConnect terminal accepts standard speaker cable or optional car-specific WireKits for non-destructive installation.

Key Features

• 3 Ω technology: maximises amplifier power output
• ProConnect terminal: automotive-grade, interlocked and reverse-polarity protected; accepts standard speaker cable or WireKit flat plugs
• 20 mm aluminium tweeter: black aluminium dome, low mass and high rigidity, for accurate, detailed highs
• Neodymium tweeter magnet: refined, highly efficient, with linear magnetic flux
• Cenosphere cone: 130 mm coated paper cone for precise reproduction
• Glass-bead reinforced basket: polymer composite that limits ringing
• Powerful magnet system: for efficiency and impulse response
• Integrated crossover: 6 dB slope
• WireKit ready: optional car-specific WireKits allow installation without cutting the vehicle wiring

Drivers & Construction

• Tweeter: coaxial 20 mm (0.75″) black aluminium dome, neodymium magnet, 20 mm voice coil
• Midbass: Paper cone with Cenosphere coating – hollow microspheres embedded in a polyamide layer raise stiffness and internal damping while keeping the cone light; 25 mm voice coil (10.5 mm winding height); ProConnect terminal
• 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
