• 50 mm advanced full-range speaker
• Silicone-coated paper cone
• 3 ohms
• Neodymium magnet
• Compatible with FlexMount50 mounting rings

The Ci5 M50FM-S3 expands the COMPOSE series with a highly advanced 2-inch broadband driver that impresses with its exceptionally fine design.

Thanks to its small outer diameter and FlexMount technology, the Ci5 M50FM-S3 can be installed even in very tight OEM mounting locations, making it particularly suitable for installation locations where space is limited or where vehicle mounting location restrictions make it difficult to implement traditional two- or three-way configurations.


The Ci5 M50FM-S3's exceptionally wide frequency response enables systems that can operate without a separate tweeter. Alternatively, the speaker also works as a great midrange in all kinds of systems with limited installation space.
