CI-22955-M11

Overview

The Knowles CI-22955-M11 is a balanced armature transducer engineered for high-performance audio applications. It features a diaphragm significantly larger than typical balanced armature drivers, enabling robust bass response with low distortion. The component operates as part of a multi-driver in-ear monitor system, specifically handling low-frequency reproduction to complement mid-range and treble units.

Feature Summary

• Large diaphragm design for enhanced bass output
• Low-distortion performance characteristics
• Optimized for compact in-ear monitor assemblies

Applications

• In-ear monitors (IEMs)
• Multi-driver audio headsets
• High-fidelity personal listening devices

Procurement Notes

Verify the specific suffix M11 against official Knowles Voltronics documentation to confirm mechanical dimensions and electrical tolerances. Ensure compatibility with existing acoustic shells and driver mounting structures. Confirm RoHS compliance status through current datasheets before integration into final consumer electronics products.

Selection Notes

Select this component when designing systems requiring dedicated bass reproduction within a balanced armature array. Its large diaphragm addresses frequency limitations common in standard BA drivers. Evaluate acoustic coupling requirements and total harmonic distortion specifications relative to paired mid and treble drivers for optimal sound staging.

Part Context

This model belongs to the CI series of balanced armature transducers from Knowles. These components are widely utilized in premium audio equipment where size constraints and acoustic precision are critical. The CI-22955 variant specifically targets the low-frequency segment of the audible spectrum.

Replacement Considerations

No public substitute part numbers are documented. Replacement requires matching the original acoustic tuning and physical footprint. Consult Knowles Voltronics engineering support for direct equivalents or updated revisions.
