The performance highlight

The HELIX COMPOSE i3 series is an absolute priceperformance highlight, engineered in Germany. As you would expect, this series matches great sound with high performance and intelligent integration possibilities: Equipped with the same smart features as i7, all mechanical highlights such as FlexMount, FlexConnect, ProConnect, COMPOSE Connect and WireKits are fully integrated.

All speaker impedances are perfectly matched for the combination with our HELIX and MATCH amplifiers, guaranteeing maximum performance and efficiency at any time. Our i3 speakers are available as single speakers as well as component and coaxial speaker systems. Additionally, almost all i7 and i3 components can both be versatilely combined in a HELIX COMPOSE sound system, granting maximum flexibility in the choice of speaker combinations as well as customer budgets.

Despite the larger diameter of 25 mm / 1”, the Ci5 T25FM-CA has an excellent wide dispersion and off-axis response, allowing the creation of an impressive sound image and stage – even in OEM installation spots. With its ceramic-coated aluminum cone, it features a balanced frequency response and excellent decay characteristics. As a result, high frequencies are reproduced even more clearly and realistically.

Thanks to the innovative Cenosphere cone, an extremely efficient magnet system and a tweeter with an exceptionally stable titanium dome, i3 guarantees a first-class sound experience. Next to the full compatibility with the mechanical technologies of the COMPOSE lineup, the i3 speaker baskets share the same technological specs with i7 and i5.

This universal crossover, optimized for use with the i3 components and suited for any combination of tweeters and midrange / woofers. Its compact dimensions facilitate installation in confined spaces. It’s also equipped with COMPOSE Connect and WireKit technologies.
