4546

Overview

The Visaton 4546 is a spherical loudspeaker with a diameter of 330 mm, belonging to the KL 33 series. It features an integrated 17 cm bass/midrange driver and operates at a nominal impedance of 4 Ohms. The unit has a power rating of 70 W and delivers a sound pressure level of 97 dBA. Its frequency response spans from 70 Hz to 18 kHz, with a maximum frequency limit of 18 kHz. The speaker is rated IP44 for protection against solid objects and water splashes.

Feature Summary

• Spherical design for omnidirectional sound dispersion
• Integrated 17 cm bass/midrange driver within a 33 cm housing
• IP44 rating suitable for protected indoor or sheltered outdoor use

Applications

• Public address systems requiring wide coverage
• Background music distribution in large spaces
• Omnidirectional audio reinforcement

Procurement Notes

Verify the specific ordering suffix to confirm impedance and voltage configuration, as part number aliases indicate variations such as 100V+4 OHM. Confirm RoHS compliance status through official documentation before procurement. Check current supply availability as stock may be restricted. Ensure mounting hardware matches the spherical basket specifications.

Selection Notes

Select this model when wide-angle sound dispersion is required without multiple directional speakers. The 70 W power handling supports high-output applications. Verify that the installation environment meets the IP44 protection requirements. Consider the 330 mm diameter for spatial constraints during integration.

Part Context

This component belongs to the Visaton KL 33 series of spherical loudspeakers. These units are designed for uniform sound distribution over a 360-degree horizontal plane. The series typically integrates midrange drivers into a spherical enclosure to minimize diffraction effects and provide consistent acoustic performance across the listening area.

Replacement Considerations

No public confirmed substitute part numbers are available.
