HELIX Ci5 T25FM-CA 25mm Ceramic-Coated Aluminium Dome Tweeters – Pair

HELIX Ci5 T25FM-CA – 25mm Ceramic-Coated Aluminium Dome Tweeters

A pair of compact 25mm tweeters with ceramic-coated aluminium domes for high-frequency reproduction. Their 4-ohm impedance, 2,000–25,000Hz response and shallow 11.7mm installation depth make them a flexible choice for a carefully matched component system. Flush mounts and tweeter pods are included.

Part of the HELIX COMPOSE i5 range, these drivers are supplied as a pair for use in a suitable custom or vehicle-adapted speaker system. Select the correct mounting hardware, wiring and crossover configuration for the installation; FlexMount compatibility alone does not establish fitment for a particular vehicle.
