Specifications

Performance and User Experience

The KU‑516 delivers commanding, intelligible audio ideal for outdoor venues, industrial settings, or emergency announcement systems. Its high sensitivity (113 dB/W/m) and robust power handling (50 W RMS) ensure sound remains clear and far-reaching, even in noisy environments. Thanks to its die‑cast construction, IP66 protection, and wide operating temperature range (−20  degreesC to +50  degreesC), this horn driver offers reliable long-term performance in challenging conditions.

Q&A Section

• Q: Can this unit be used with 8 Ω amplifiers?
  A: No--this is a 16 Ω passive horn driver and must be connected to a compatible 16 Ω low‑impedance amplifier.
• Q: How well does it handle outdoor elements?
  A: It is IP66‑rated, so it's highly resistant to dust ingress and powerful water jets--excellent for outdoor use.
• Q: What kind of mounting is required?
  A: It uses a 3.5 cm (1⅜") mounting flange and comes with screw‑terminal input for straightforward installation.
• Q: What environments and weather can it withstand?
  A: It operates reliably between −20  degreesC and +50  degreesC and is built to endure harsh weather and industrial environments.
• Q: What is the expected volume output?
  A: With 113 dB/W/m sensitivity and 50 W RMS power capability, it offers powerful and clear audio projection over long distances.
