SL 87 WPM - 8 OHM

Overview

The Visaton SL 87 WPM - 8 OHM is a waterproof, weather-resistant full-range speaker designed for outdoor environments. It features an 8 cm (3.3 inch) transparent plastic cone and a rubber sealing ring to ensure IP65 protection against dust and water jets. The unit operates with an 8 Ohm impedance and handles up to 20 Watts of power. Its frequency response spans from 200 Hz to 5 kHz, delivering a sound pressure level of 89 dBA at 1W/1m. The compact design includes solder lug terminals and supports panel mounting within a temperature range of -40°C to +70°C.

Feature Summary

• Waterproof construction with IP65 rating utilizing a transparent plastic cone and rubber sealing ring
• Weather and UV resistant design suitable for harsh outdoor conditions
• Compact round frame configuration optimized for space-constrained installations

Applications

• Outdoor public address systems requiring weather resistance
• Marine audio equipment installation
• Industrial communication devices exposed to moisture or dust
• Public information displays in open-air environments

Procurement Notes

Verify the specific impedance variant required for your circuit, as this model is distinct from the 4 Ohm version. Confirm that the 200 Hz lower frequency limit meets your application needs, as it lacks deep bass extension. Ensure the panel cutout dimensions align with the 83 mm diameter specification. Check terminal compatibility with solder lugs rather than quick-connect tabs. Validate environmental ratings against local exposure conditions.

Selection Notes

Select this component when high durability and water resistance are prioritized over wide-bandwidth audio fidelity. The 8 Ohm impedance suits amplifier outputs designed for higher impedance loads. Consider the limited low-frequency response below 200 Hz when designing enclosure systems. The transparent cone may influence aesthetic requirements compared to traditional paper or polymer cones. Panel mounting constraints must accommodate the 29 mm depth.

Part Context

This speaker belongs to the SL 87 WPM series, which focuses on robust, weather-proof audio solutions. Unlike standard indoor speakers, these units utilize specialized materials to withstand environmental stressors. The series is commonly integrated into infrastructure where maintenance access is difficult or environmental exposure is constant. It serves as a direct replacement for failed units in existing outdoor audio deployments requiring identical form factors.

Replacement Considerations

Visaton SL 87 WPM - 4 OHM offers identical physical dimensions and weather resistance but requires matching 4 Ohm amplifier outputs. Other Visaton waterproof models may share the IP65 rating but differ significantly in size, impedance, or frequency response characteristics.
