JBL CSS-H15 - 15W 1.3-inch Passive Full-Range IP65-Rated 70V/100V Surface-Mount Paging Horn Loudspeaker with 70 x 90-Degree Coverage in White Finish

The JBL Professional CSS-H15 is a 15W 1.3-inch passive full-range surface-mount paging horn loudspeaker, designed to deliver exceptional voice clarity and high performance in public address and paging systems. With an IP65-rated enclosure and rugged construction, this paging horn is engineered to withstand challenging environmental conditions, making it suitable for indoor and outdoor installations. Ideal for applications in warehouses, factories, schools, recreational facilities, and civic centers, the CSS-H15 features a wide 70° horizontal by 90° vertical coverage pattern, ensuring uniform sound dispersion over medium throw distances. The paging horn's phenolic diaphragm driver provides reliable performance and durability under extreme conditions, resisting deformation from temperature fluctuations and long-term use.

The CSS-H15 integrates a UL-registered 15W multi-tap transformer for compatibility with 70V and 100V distributed speaker systems, with selectable power taps of 15W, 7.5W, 3.8W, 1.9W, and 0.9W (70V only). For non-distributed systems, an 8-ohm direct bypass mode is available. A screwdriver-adjustable switch on the rear allows for easy power tap selection. The speaker features a built-in 350 Hz high-pass filter, protecting the driver from low-frequency damage and enhancing reliability. Its high sensitivity of 105 dB ensures clear, intelligible audio with minimal amplification, delivering a maximum SPL of 123 dB continuous average and 129 dB peak at 15W input.

The paging horn is constructed from sturdy ABS plastic with a stainless steel U-bracket and hardware for secure mounting. The included bracket allows for flexible installation, enabling precise aiming and positioning to cover large audience areas effectively. The horn's weather-resistant materials, including a watertight cable fitting and stainless steel hardware, ensure durability in harsh outdoor environments. Compact dimensions of 6.5 x 8.8 x 9.2 inches (horn only) and a lightweight design of 3.0 lbs make the CSS-H15 easy to install in various locations. Whether for paging, intercoms, security systems, or alarms, this paging horn offers dependable performance and excellent voice range clarity.
