Each unit applies a 12 dB highpass slope to the tweeter, provides six-stage level adjustment from -5 dB to +2 dB, and includes integrated tweeter protection. Two COMPOSE Connect kits are supplied for a polarity-safe, solder-free connection to automotive standards.
Who it suits
This crossover suits anyone building a COMPOSE i3 component install, and is compatible with all i3 drivers including the Ci3 T20FM-TI tweeter and the Ci3 W165FM-S3, W130-S3 and W200FM-S3 midbass units. Those wanting a higher-specification option can consider the Helix Compose i7 Ci7 FX-UNI.2 for the i7 series.
Our tech experts advise
When using i3 midbass drivers such as the Ci3 W165FM or W130, you will also need the separately available Ci3 FX-WLP.2 lowpass cable crossover. The six-stage tweeter level control lets you balance treble output to suit the mounting position without additional DSP adjustment. Installation is priced per vehicle; visit our car audio installation page for details.
