Speakers Overview

The Visaton DK 121 - 100 V is a built-in horn loudspeaker designed for 100 V constant voltage line applications. It features a waterproof construction with a black lacquered aluminum housing and polypropylene horns. The unit delivers a sound pressure level of 100 dB at 1W/1M, operating within a frequency range of 570 Hz to 4.4 kHz. It is engineered for flush mounting or recessed installation in public address systems requiring high durability and weather resistance.

Speakers Feature Summary

• Waterproof design suitable for outdoor or harsh environments
• Integrated 100 V transformer for direct connection to constant voltage lines
• Durable construction using black lacquered aluminum housing and polypropylene components

Speakers Applications

• Public address systems requiring weather-resistant speakers
• Flush mount installations in commercial buildings
• Recessed speaker setups for background music distribution

Speakers Procurement Notes

Verify the specific model suffix to ensure compatibility with existing 100 V line infrastructure. Confirm that the required mounting depth aligns with the physical dimensions of the aluminum housing. Check local regulations regarding IP ratings if the installation environment involves direct exposure to water or dust. Ensure the amplifier output matches the 6 W power rating to prevent distortion or damage.

Speakers Selection Notes

Select this component when a weatherproof solution is required for 100 V distributed audio networks. It is appropriate for projects needing a compact, recessed form factor with high efficiency. Consider the frequency response limitations for applications requiring full-range audio reproduction rather than speech-only clarity.

Speakers Part Context

This model belongs to Visaton's line of built-in horn speakers designed for professional audio distribution. It complements other Visaton products by offering a specialized solution for constant voltage systems where environmental protection and discreet installation are prioritized over wide-bandwidth musical fidelity.

Speakers Replacement Considerations

Direct substitutes must support 100 V operation and similar SPL ratings. Verify mechanical dimensions for flush-mount compatibility. Alternative models may differ in housing material or horn geometry, affecting acoustic dispersion patterns.
