SW440804-1

Overview

The SW440804-1 is a waterproof flush mount dynamic micro speaker manufactured by DB Unlimited. It features a nominal impedance of 4 Ohms and a maximum power handling capacity of 2.5 W, with a rated power of 2 W. The device delivers a sound pressure level of 92 dBA at 10 cm. Its frequency range spans from 800 Hz to 10 kHz, with a self-resonant frequency of 800 Hz. The unit weighs 1.4 g and utilizes a polyethylene terephthalate (PET) cone. Dimensions are 44.6 mm in diameter and 8.3 mm in height.

Feature Summary

• Waterproof construction with IP67 rating for reliable operation in wet environments
• Flush mount design suitable for space-constrained enclosures
• Lightweight build using PET cone material for efficient acoustic performance

Applications

• Marine audio equipment requiring water resistance
• Outdoor electronic devices exposed to moisture
• Compact consumer electronics needing low-profile speakers

Procurement Notes

Verify the specific impedance and power ratings against your circuit requirements before integration. Confirm that the flush mount dimensions fit your enclosure design constraints. Ensure the operating temperature range of -20 C to +55 C aligns with your application environment. Check for any specific mounting hardware requirements not included with the component.

Selection Notes

Select this model when a compact, water-resistant speaker is required for flush installation. The 4 Ohm impedance suits standard amplifier outputs. Consider the 92 dBA sensitivity for applications needing moderate volume without excessive power consumption. Evaluate the 800 Hz to 10 kHz frequency response against your audio bandwidth needs.
