About the Helix CI42501
From our tech experts at CEN
The Helix CFMK25 PSA.1 is a two-part FlexMount25 tweeter adaptor set for Peugeot and Citroën vehicles with a factory tweeter. It includes two FlexMount25 rings plus two reducer rings, so it accepts either a 1 inch (25 mm) or a 0.75 inch (20 mm) Helix Compose FlexMount tweeter.
Who it suits
Peugeot and Citroën owners upgrading the factory tweeters in their original position. It suits the 1 inch Ci5 T25FM-CA on its own, or 20 mm tweeters such as the Ci3 T20FM-TI, Ci7 T20FM-SC and CB T20FM-S with the reducer fitted.
Our tech experts advise
Choose the tweeter before fitting, as the reducer ring is only needed for 20 mm models. PSA tweeter mounts are not identical across every model, so check your car has a factory tweeter first. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm it fits.
