RAF-32873-000

Speakers Overview

The Knowles RAF-32873-000 is a single full-range balanced armature receiver designed for high-fidelity audio applications. It features a vented design with an impedance of 50 Ohms and delivers a maximum sound pressure level (SPL) of 117 dB. The operational frequency range spans from 200 Hz to 11 kHz, with the acoustic port located on the top surface. This component utilizes a balanced armature driver architecture optimized for compact form factors while maintaining wide bandwidth capabilities.

Speakers Feature Summary

• Vented balanced armature design for enhanced acoustic performance
• Wide frequency bandwidth suitable for full-range audio reproduction
• High sensitivity output capability for efficient signal conversion

Speakers Applications

• In-Ear Monitor (IEM) systems
• High-fidelity audio receivers
• Compact hearing aid devices

Speakers Procurement Notes

Verify the specific datasheet version and RoHS compliance status prior to integration. Confirm that the 50 Ohm impedance matches the target amplifier output requirements. Ensure mechanical dimensions and port location align with the enclosure design constraints. Validate that the 117 dB SPL rating meets the intended application's volume specifications without distortion.

Speakers Selection Notes

Select this component when a single-driver solution requires broad frequency coverage within a small footprint. The 50 Ohm impedance offers compatibility with standard audio interfaces. Consider the vented design benefits for bass response in constrained spaces. Evaluate the 200 Hz to 11 kHz range against the specific spectral requirements of the target audio system.

Speakers Part Context

This part belongs to Knowles' balanced armature driver portfolio, specifically engineered for precision audio applications. It represents a specialized receiver unit distinct from general-purpose speakers. The design focuses on delivering warm bass characteristics and excellent price-performance ratios within the micro-acoustic segment.

Speakers Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Cross-referencing requires matching the 50 Ohm impedance, 117 dB SPL, and 200 Hz–11 kHz frequency range. Mechanical fit and port orientation must be verified for any potential alternative components.
