DL 18/2 SQ - 8 OHM/100 V

Speakers Overview

The Visaton DL 18/2 SQ - 8 OHM/100 V is a dual-cone electromagnetic speaker transducer designed for high-efficiency audio reproduction. It features an 8-ohm direct impedance and an integrated 100-volt transformer, allowing compatibility with constant-voltage distribution systems. The unit utilizes solder lug termination for secure electrical connections and supports panel mounting configurations. With a power rating of 500 mW and a frequency response range extending from 300 Hz to 19,000 Hz, it delivers a sound pressure level of 74 dBA. The compact round design measures 22 mm in diameter and 23 mm in length, weighing 5 g, and operates reliably within a temperature range of -20°C to +65°C.

Speakers Feature Summary

• Integrated 100 V transformer enables direct connection to constant-voltage public address lines without external matching equipment.
• Dual-cone electromagnetic construction provides balanced frequency response and enhanced acoustic output efficiency.
• Robust IP64 ingress protection rating ensures resistance against dust accumulation and water splashes for durable operation.
• Solder lug termination facilitates straightforward integration into custom electronic assemblies and control panels.

Speakers Applications

• Public address systems requiring distributed audio coverage via 100 V line architecture
• Industrial communication devices needing reliable speech intelligibility in noisy environments
• Security and alarm systems utilizing standardized constant-voltage speaker networks
• Compact electronic enclosures where space constraints limit the use of larger transducers

Speakers Procurement Notes

Verify that the specific order includes the integrated 100 V transformer component, as standard variants may lack this feature. Confirm the impedance specification matches the system's amplifier output requirements to prevent mismatch issues. Ensure installation procedures adhere to the specified operating temperature limits to maintain performance integrity. Check for RoHS compliance documentation if environmental regulations apply to the deployment location.

Speakers Selection Notes

Choose this model when both direct low-impedance driving and high-impedance line distribution are required within a single compact unit. The integrated transformer simplifies wiring complexity compared to separate matching transformers. Consider the physical dimensions and weight constraints for panel mounting applications. Evaluate the frequency response characteristics against the specific audio content requirements, noting the limitations in deep bass reproduction due to the small driver size.

Speakers Part Context

This component belongs to Visaton's K 23 SQ series of mini speakers, which are engineered for high reliability in professional audio and industrial applications. The series emphasizes compact form factors combined with robust acoustic performance. The DL variant specifically denotes the dual-cone design, offering improved mechanical stability and acoustic coupling compared to single-cone counterparts within the same product family.

Speakers Replacement Considerations

No publicly confirmed substitute part numbers are available for this specific configuration. Direct replacements must match the 100 V transformer integration, 8 Ohm base impedance, and physical mounting dimensions. Verify that any alternative component meets the same IP64 rating and power handling capabilities to ensure system compatibility.
