Helix Ci7 M100FM-S3 midrange speakers (100 mm).

HELIX Ci7 M100FM-S3 midrange speaker 4" (100 mm). 

Helix COMPOSE i7 series represents uncompromising high-end for an outstanding sound experience in the automobile. 
With obvious influence of the high-end sister brand BRAX, the i7 speaker series is completely made in Germany and optimized for uncompromising music enjoyment: 
- Only the highest quality materials such as the ultra high damping crafted paper cone are used in order to achieve a maximum impulse and an unmatched frequency response. 

The speaker baskets are made of a high-tech polymer composite, which is additionally reinforced with glass beads for maximum rigidity and minimum ringing. 
Last but not least, there are our extraordinarily powerful, highly efficient magnet systems as well as the tweeter with hand-coated silk dome and coupling volume. 
The 100 mm COMPOSE speaker particularly stands out due to its flat design and large diaphragm area. 
Of course, the i7 series is compatible with all HELIX COMPOSE technologies such as FlexMount, FlexConnect, ProConnect and the WireKits.
