JBL CSS H15 15W Megaphone Speaker

JBL Professional CSS-H15 - 15W IP65 PA Horn with 70/100V Transformer (70° × 90° Coverage)

The JBL Professional CSS-H15 is a Commercial Solutions Series PA horn optimized for clear medium/long-distance voice in paging, security, and signaling systems. Its 70° (H) × 90° (V) pattern concentrates energy in the useful area, while the high sensitivity (105 dB, average 1–6 kHz) delivers high levels with low power. It incorporates a 70/100 V multi-tap transformer with 8 Ω bypass and an integrated high-pass filter (350 Hz) that protects the transducer from out-of-band frequencies. Constructed from ABS with a U-bracket and stainless steel hardware , it has an IP65 protection rating for indoor and outdoor use. It is supplied with a 300 mm hose with a watertight cable gland for safe and fast installation.

• Efficiency on distributed lines : fine taps (up to 0.9 W) to balance zones and save power.
• Outdoor durability : IP65, phenolic diaphragm and stainless steel hardware for long life.
• Simple and safe installation : bracket included, watertight input and 8 Ω option without transformer.
