SL 87 XA - 4 OHM

Overview

The Visaton SL 87 XA - 4 OHM is a waterproof full-range speaker featuring a transparent plastic cone and rubber sealing ring. It operates with a nominal impedance of 4 Ohms and a power rating of 20 W. The unit delivers a sound pressure level of 89 dBA at 1W/1m, with a frequency range spanning 290 Hz to 5000 Hz. Its self-resonant frequency is 290 Hz. The speaker measures 85.5 mm in diameter and 29 mm in depth, utilizing solder lug terminals for connection.

Feature Summary

• Waterproof construction with IP65 rating
• Transparent plastic cone design
• Rubber sealing ring integration

Applications

• Outdoor audio installations
• Marine environments
• Weather-exposed enclosures

Procurement Notes

Verify the specific model suffix against official Visaton documentation to ensure correct impedance and cone material specifications. Confirm that the transparent plastic cone variant matches the required aesthetic or functional needs. Cross-reference datasheet parameters such as frequency response and power handling before finalizing procurement decisions.

Selection Notes

Select this component when weather resistance is critical for outdoor or marine applications. The transparent cone offers visual distinctiveness compared to standard black cones. Ensure the 4 Ohm impedance aligns with the amplifier output requirements. Consider the 290 Hz low-frequency limit for bass performance expectations.

Part Context

This model belongs to the SL 87 WPM series of waterproof speakers from Visaton. It shares the same physical dimensions and general waterproofing features as other variants in the series but differs in cone material and impedance. The SL 87 XA specifically utilizes a transparent plastic cone, distinguishing it from opaque cone alternatives within the same product family.

Replacement Considerations

Visaton SL 87 ND - 8 OhM uses a neodymium magnet and has 8 Ohm impedance. Visaton SL 87 WPM - 4 OHM has similar specs but may differ in cone transparency.
