K 64 WP - 50 OHM

Speakers Overview

The K 64 WP - 50 OHM is a general-purpose full-range speaker manufactured by Visaton GmbH & Co. KG. It features a 64.00 mm (2.520 inch) diameter top-mount round design with quick connect terminals. The unit operates at a nominal impedance of 50 Ohms and has a power rating of 2 W. The frequency response spans from 300 Hz to 15 kHz, delivering a sound pressure level of 86 dB.

Speakers Feature Summary

• Top-mount round construction for panel installation
• Quick connect terminal termination method
• General-purpose audio reproduction capability

Speakers Applications

• Public address systems
• Intercom units
• Annunciator panels

Speakers Procurement Notes

Verify the specific impedance requirement of 50 Ohms against the amplifier output stage, as this differs from standard 4 or 8 Ohm configurations. Confirm that the 2 W power rating aligns with the intended signal levels to prevent thermal damage. Ensure the mounting hole dimensions accommodate the 64 mm diameter chassis. Check for RoHS compliance status if required by project specifications.

Speakers Selection Notes

Select this component when a high-impedance 50 Ohm input is required for legacy or specific line-level audio distribution systems. The 2 W rating suits low-volume announcement applications rather than high-fidelity music reproduction. Consider the 300 Hz lower frequency limit, which may require crossover networks if full-range coverage is necessary in complex audio setups.

Speakers Part Context

This model belongs to Visaton's range of general-purpose speakers designed for voice and alert applications. Unlike high-fidelity drivers, these units prioritize durability and compatibility with constant-voltage or high-impedance distribution lines commonly found in commercial building infrastructure and industrial signaling equipment.

Speakers Replacement Considerations

Direct substitutes must match the 50 Ohm impedance and 64 mm form factor. Generic 8 Ohm replacements will cause mismatch issues in high-impedance circuits. Verify terminal type compatibility, as quick-connect tabs differ from screw terminals.
