RDU-35000-000

Speakers Overview

The Knowles RDU-35000-000 is a dual balanced armature super tweeter driver designed for high-end in-ear monitor applications. It features a rectangular metal construction with dimensions of 5.1mm x 4.1mm x 2.8mm. The component operates at an impedance of approximately 7 Ohms and delivers a maximum sound pressure level (SPL) of 127 dB. Sensitivity is rated at 109 dB SPL at 100mV, with a total harmonic distortion (THD) of 0.2%. This receiver assembly is packaged in bulk quantities.

Speakers Feature Summary

• Dual balanced armature architecture optimized for super tweeter frequency ranges
• Rectangular metal housing providing structural durability
• High sensitivity output suitable for low-power audio drivers

Speakers Applications

• High-end in-ear monitor (IEM) systems
• Premium audio receiver assemblies
• Super tweeter driver integration

Speakers Procurement Notes

Verify the specific datasheet version when ordering, as manufacturer documentation may contain updated electrical tolerances or mechanical drawings. Confirm packaging details, as sources indicate bulk packaging but quantity per pack may vary by distributor. Ensure compatibility with existing IEM acoustic chambers given the precise 5.1x4.1x2.8mm form factor. Cross-reference impedance values between 7.0 and 7.2 Ohms depending on the specific test conditions cited in the latest official documentation.

Speakers Selection Notes

Select this component for designs requiring a dedicated super tweeter channel within a multi-driver in-ear monitor configuration. The dual balanced armature design offers distinct advantages in high-frequency extension compared to single-armature units. Consider the rectangular footprint when designing PCB layouts or acoustic tubes. Verify that the 127 dB max SPL meets the dynamic range requirements of the target audio application without clipping.

Speakers Part Context

This part belongs to Knowles' premium balanced armature driver lineup, specifically engineered for audiophile-grade audio equipment. It serves as a specialized transducer component rather than a general-purpose speaker. The RDU series focuses on delivering extended high-frequency response through dual-armature technology, distinguishing it from standard full-range or bass-midrange balanced armature receivers used in consumer electronics.

Speakers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Knowles directly for equivalent models with compatible impedance and dimensional constraints.
