Helix CI5 M50FM-S3 (CI21200) advanced 50 mm / 2 inch full-range speaker with 3 Ω impedance, FlexMount50 technology and exclusive silicon-coated paper cone

The HELIX COMPOSE i5 series represents the bridge between the i7 series and the i3 series, designed for the most demanding music enthusiasts who desire a true hi-fi experience. The result of combining phenomenal sound with unparalleled practicality: developed with the goal of creating speakers with unique characteristics, but also capable of concretely solving problems. All speaker impedances are perfectly matched for pairing with our HELIX and MATCH amplifiers, guaranteeing maximum performance at all times. Furthermore, we have implemented our exclusive mechanical technologies from the COMPOSE series, which offer unbeatable practical advantages.

Full-range audiophile performance for flexible integrations

The Ci5 M50FM-S3 expands the COMPOSE platform with a highly advanced 2" full-range driver that impresses with its exceptionally compact design: thanks to the significantly reduced external diameter compared to typical 2" drivers and the FlexMount technology implemented, the Ci5 M50FM-S3 can be installed even in very tight OEM mounting spaces. This makes it particularly suitable for installation positions where space constraints, unfavorable mounting angles or OEM housing limitations make it difficult to implement conventional two or three-way configurations.

Its exceptionally wide usable frequency range allows system configurations that can operate without a separate tweeter. The high power handling and clean, low-distortion reproduction of high frequencies make it also an excellent choice for midrange applications, full-range systems or DSP-based configurations that require exceptional sound quality in minimal space.
