About the Helix CI42503
From our tech experts at CEN
The Helix CFMK25 VW.1 is a two-part FlexMount25 tweeter adaptor set for a range of Volkswagen, Skoda and Seat vehicles. It contains two FlexMount25 rings and two reducer rings, so it takes either a 1 inch (25 mm) or a 0.75 inch (20 mm) Helix Compose FlexMount tweeter.
Who it suits
Volkswagen, Skoda and Seat owners who want the option of the 1 inch Ci5 T25FM-CA. With the reducers fitted it also takes 20 mm tweeters such as the Ci3 T20FM-TI. For a 20 mm-only fit in a different VW mount, Helix also makes the CFMK20 VW.2.
Our tech experts advise
Volkswagen group cars use more than one tweeter mount, so check your model before choosing between this and the CFMK20 VW.2. Fit the reducer only when using a 20 mm tweeter. Installation is priced per vehicle, so send us your make, model and year and we will confirm the right ring.
