Description
HELIX Compose Ci3 T20FM-AL MK2
The Ci3 T20FM-AL MK2 is the tweeter from Helix’s Compose i3 range, the price-performance step within the Compose family and part of the platform that won the EISA Best Product award for in-car integration (2023-2024). It uses a black aluminium dome with a neodymium magnet system, and it’s the tweeter supplied in Helix’s current Ci3 MK2 component sets.
Sensitivity is 91 dB at 2.83 V and the tweeter covers 2,000 Hz to 25,000 Hz at 4 Ohms. With only 9.8 mm mounting depth it fits tight dash and mirror-triangle locations, and Helix’s FlexMount20 rings and WireKits make vehicle-specific installs clean and simple. Mounting pods for flush and angled mounting are included.
Recommended high-pass: above 5,000 Hz at 6 dB/octave, above 3,500 Hz at 12 dB/octave, or above 3,000 Hz at 24 dB/octave.
