RDE-33729-000

Speakers Overview

The Knowles RDE-33729-000 is a balanced armature transducer designed for high-fidelity audio applications. It features a resonant frequency of approximately 1.5 kHz and an impedance of 32 ohms. The device utilizes a neodymium magnet system to achieve high sensitivity, typically around 108 dB SPL/mW at 1 kHz. Constructed with durable materials, it supports continuous power handling suitable for multi-driver in-ear monitor configurations.

Speakers Procurement Notes

Verify the specific suffix against the official Knowles datasheet to ensure correct impedance and sensitivity tolerances. Confirm RoHS compliance status and packaging requirements directly with the manufacturer or authorized distributors before finalizing orders.

Speakers Selection Notes

Select this component for applications requiring precise mid-frequency reproduction and compact size. Ensure the driver's impedance matches the crossover network design. Evaluate thermal performance if used in high-power scenarios within sealed enclosures.

Speakers Part Context

Part of the Knowles Precision Audio portfolio, specifically the RDE series. Designed for integration into complex acoustic assemblies where space is limited and sound quality is critical. Complements other Knowles drivers like the WBFK series for full-range coverage.

Speakers Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Cross-reference with other Knowles balanced armature models such as the RDE-33728 or similar series parts, ensuring mechanical dimensions and electrical parameters align.
