SW870508-1

Overview

The SW870508-1 is a round dynamic speaker manufactured by DB Unlimited, designed for high-durability applications. It features an 8-ohm impedance and a power rating of 10 watts. The unit delivers a sound pressure level of 106 dBA with a resonant frequency of 390 Hz. Its physical dimensions are 87 mm in diameter and 32 mm in height. The speaker incorporates solder eyelets for termination and carries an IP67 ingress protection rating, ensuring resistance to dust and water immersion.

Feature Summary

• IP67 rated waterproof construction suitable for harsh environments
• High sound pressure output of 106 dBA
• Robust 10-watt power handling capability
• Durable design with integrated solder eyelet connections

Applications

• Outdoor audio equipment requiring weather resistance
• Industrial control panels needing durable acoustic signaling
• Marine or coastal electronic enclosures
• Public address systems in exposed locations

Procurement Notes

Verify the specific suffix variant required, as DB Unlimited offers related models like SW870508-2 with similar specifications but potential differences in porting or mounting. Confirm that the IP67 rating aligns with your environmental exposure requirements. Ensure the 8-ohm impedance matches your amplifier output capabilities. Check for availability constraints as distribution may vary by region.

Selection Notes

Select this model when high durability and waterproofing are critical alongside moderate-to-high volume output. The 10-watt rating supports robust performance without excessive power consumption. Consider the 87 mm diameter for enclosure space planning. The solder eyelet termination simplifies assembly compared to PCB mount alternatives. Evaluate if the 390 Hz resonant frequency suits the target application's acoustic needs.

Part Context

This component belongs to DB Unlimited's Durable series, which focuses on ruggedized audio transducers. The SW prefix typically denotes speakers within their product line. These units are engineered to withstand challenging conditions where standard consumer-grade speakers would fail. The series emphasizes longevity and consistent performance in demanding operational settings.

Replacement Considerations

SW870508-2 is a documented alternative from the same manufacturer with identical core electrical parameters including 8-ohm impedance and 10W rating. Verify mechanical fit and terminal style compatibility before substitution. Other generic IP67 speakers may not match the specific 106 dBA output or dimensional constraints.
