Helix Ci7 FX-UNI.2 – Universal 2-Way High-End Flex-Crossover for COMPOSE i7
The Ci7 FX-UNI.2 is the passive 2-way crossover of the HELIX COMPOSE i7 line, built with high-grade components for frequency separation in vehicle-integrated installations. Tweeter level and woofer lowpass can each be set in four stages to suit the mounting position.
Its Flex-Crossover design can be separated, which helps in vehicles where tweeter and woofer sit in different locations. Connections are made with the plug-in COMPOSE Connect system, and optional car-specific WireKits allow non-destructive connection to the factory wiring.
