AS02704MS-N50-LW100-R

Overview

The PUI Audio AS02704MS-N50-LW100-R is a general-purpose speaker from the N50 Mini Speaker Series. It features a square panel mount design with a polymer cone, rubber surround, and PE gasket for dust protection. The unit operates at an impedance of 4 Ohms with a self-resonant frequency of 350 Hz. It delivers an efficiency of 79 dBA and supports a frequency range of 300 Hz to 20 kHz. Power handling is rated at 2.5 Watts.

Feature Summary

Square frame construction with polymer cone and rubber surround
PE gasket integration for enhanced dust protection
Panel mount installation style

Applications

General purpose audio output devices
Miniature speaker assemblies requiring dust resistance
Panel-mounted audio equipment

Procurement Notes

Verify the specific power rating (2W vs 2.5W) against the official datasheet before finalizing designs. Confirm that the square form factor and panel mount requirements align with the enclosure constraints. Ensure the 4-ohm impedance matches the amplifier output specifications to prevent mismatch issues.

Selection Notes

Select this component when a compact square speaker with integrated dust protection is required. The N50 series offers a balance of size and performance suitable for miniaturized applications. Consider the 350 Hz self-resonant frequency when designing acoustic enclosures to optimize low-frequency response.

Part Context

This part belongs to the N50 Mini Speaker Series by PUI Audio. It is designed as a general-purpose driver with a focus on durability through its gasketed construction. The square geometry distinguishes it from standard round speakers in the same series, allowing for tighter packing in rectangular enclosures.
