K 50 WP - 50 OHM

Speakers Overview

The Visaton K 50 WP - 50 OHM is a 5 cm (2-inch) full-range speaker designed for general-purpose audio applications. It features a plastic diaphragm and basket, offering a frequency response of 180 Hz to 17 kHz with an efficiency of 84 dBA. The unit has a nominal impedance of 50 Ohms and a power rating of 2/3 W. It carries an IP65 rating, indicating protection against dust and low-pressure water jets, making it suitable for outdoor or harsh environments.

Speakers Feature Summary

• IP65 rated enclosure for dust and water resistance
• Compact 5 cm diameter design for space-constrained installations
• Plastic diaphragm construction for durability

Speakers Applications

• Outdoor public address systems
• Industrial machine signal output
• General-purpose voice reproduction equipment

Speakers Procurement Notes

Verify the specific impedance variant (50 Ohm vs 8 Ohm) as Visaton produces multiple versions of the K 50 WP series. Confirm the exact power handling requirements match the 2/3 W rating for your application. Check for updated datasheets regarding the IP65 certification details and mounting dimensions to ensure mechanical compatibility with your housing design.

Speakers Selection Notes

Select this model when high environmental protection (IP65) is required alongside compact size. The 50 Ohm impedance is distinct from common 4 or 8 Ohm speakers; ensure your amplifier or transformer matches this specific load. Consider the limited power handling (2-3 W) for low-volume signaling rather than high-fidelity music playback.

Speakers Part Context

This component belongs to the Visaton K 50 WP series, which includes variants with different impedances such as 8 Ohm and 50 Ohm. These are miniature full-range drivers characterized by their small form factor and robust plastic construction. The series is widely used in industrial and outdoor audio applications where durability and weather resistance are prioritized over high-power handling.

Speakers Replacement Considerations

Direct substitutes must match the 50 Ohm impedance and IP65 rating. Generic 5 cm speakers typically lack the specific weather sealing. Verify that any replacement maintains the 180 Hz lower frequency limit and similar sensitivity to avoid volume discrepancies.
