RAU-34832-B148

Speakers Overview

The Knowles RAU-34832-B148 is a micro-sized balanced armature receiver assembly designed for premium audio applications. It features a rectangular shape with dimensions of 5.1 x 2.8 x 2.0 mm and a height of 2 mm. The component operates at an impedance of 14 Ohms and delivers a sound pressure level of 122 dBA. This single-driver unit functions as a supertweeter, providing high-frequency reproduction capabilities suitable for in-ear monitor systems.

Speakers Feature Summary

• Micro-sized rectangular form factor optimized for compact audio devices
• Balanced armature transducer technology for precise treble performance
• High sensitivity output suitable for professional audio monitoring

Speakers Applications

• Audiophile in-ear monitors (IEMs)
• Hi-Res Audio Wireless TWS earphones
• Professional in-ear monitoring systems

Speakers Procurement Notes

Verify the specific datasheet version to confirm mechanical tolerances and acoustic parameters. Ensure compatibility with existing driver housings due to the precise 5.1 x 2.8 mm footprint. Confirm that the 14 Ohm impedance aligns with the target crossover network design for optimal frequency response integration.

Speakers Selection Notes

Select this component when high-frequency extension and clarity are prioritized in a constrained space. The 122 dBA sensitivity indicates efficient power conversion, reducing amplifier load requirements. Consider the rectangular geometry for directional sound projection needs within tight earpiece enclosures compared to circular drivers.

Speakers Part Context

This model belongs to Knowles' RAU series of micro-balanced armature drivers. It is specifically engineered as a supertweeter to complement mid-range and bass drivers in multi-driver IEM configurations. The series emphasizes miniaturization while maintaining audiophile-grade acoustic performance standards.

Speakers Replacement Considerations

Direct substitutes must match the 5.1 x 2.8 x 2.0 mm dimensions and 14 Ohm impedance. Verify that alternative supertweeters provide comparable SPL ratings to maintain tonal balance in existing multi-driver assemblies.
