HELIX CI3 W165FM-S3 pair of 165 mm woofers - Compose i3


The HELIX COMPOSE i3 series is an absolute excellence in terms of price and performance, offering a first-class sound experience thanks to high-quality components and intelligent design.

HELIX COMPOSE implements a highly efficient 3 Ohm technology and harmonizes perfectly with all HELIX and MATCH amplifiers while at the same time enabling a clearly perceptible advantage in terms of efficiency and maximum sound pressure. With the innovative "Cenosphere" coating, hollow spheres are incorporated into a polyamide layer applied to the cone. This process increases rigidity and optimizes internal damping. The result is an exceptionally stable and lightweight cone that delivers exceptional precision in sound reproduction.

All CI3 W165FM-S3 baskets are made from a high-tech composite polymer, further reinforced with glass spheres. The result is maximum stability with minimal self-resonance, while eliminating magnetic flux modulation and maximum resistance to thermal influences. Last but not least, this allows for much more compact basket dimensions and therefore simplified installations in confined space conditions.
