• Waterproof construction suitable for outdoor environments
• Top port configuration for optimized acoustic output

Speakers Applications

• Outdoor public address systems
• Industrial communication setups
• Weather-resistant audio installations

Speakers Procurement Notes

Verify the exact part number DK 133 - 8 OHM against official Visaton documentation to ensure correct impedance and power specifications. Confirm environmental ratings if deployment involves extreme temperatures or moisture. Cross-reference datasheet revisions for any updates in mounting dimensions or electrical characteristics before finalizing procurement orders.

Speakers Selection Notes

Select this model when high efficiency and weather resistance are required for fixed installations. The 8-ohm impedance suits standard amplifier outputs. Consider the 106 dBA sensitivity for long-distance coverage needs. Ensure the panel mount style fits the intended enclosure structure. Verify that the 570 Hz to 4.4 kHz frequency response meets the specific audio reproduction requirements.

Speakers Part Context

This component belongs to Visaton's line of general-purpose speakers designed for robust performance. It differs from the DK 133 - 100 V variant by using an 8-ohm direct connection instead of a 100-volt transformer system. Both share similar physical dimensions and waterproof capabilities but serve different distribution architectures in audio networks.

Speakers Replacement Considerations

Visaton DK 133 - 100 V serves as a functional alternative for 100V line systems. Direct 8-ohm replacements require matching impedance and sensitivity. Verify dimensional compatibility for existing mounts. Ensure frequency response overlaps sufficiently for seamless integration without significant tonal shifts.
