JBL CSS8004 - 15W 4-inch Passive 70V/100V Ceiling Loudspeaker with 5W Multi-Tap Transformer and 175-Degree Coverage in White Finish

The JBL Professional CSS8004 is a high-performance 15W, 4-inch passive ceiling loudspeaker designed to meet the needs of paging and background music applications. With its exceptional sensitivity of 90 dB, the CSS8004 ensures clear and powerful sound output, even at low tap settings, making it ideal for spaces such as retail stores, restaurants, schools, and other facilities. This speaker is equipped with a versatile 5W multi-tap transformer that supports 100V, 70V, and 25V distributed loudspeaker lines, providing maximum flexibility for various installation needs. The pre-attached transformer and grille assembly simplify installation, while the high-quality components ensure long-term reliability and performance.

The driver of the CSS8004 is a dual-cone type with a 100 mm (4-inch) diameter and a 25 mm (1-inch) voice coil made from high-temperature wire and Kapton coil-formers, designed to handle continuous power of up to 15 Watts. The speaker's frequency range is impressive, offering a broad spectrum of sound from 85 Hz to 18 kHz when the driver/grille assembly is used, and from 130 Hz to 18 kHz when installed with the CSS-BB backcan. The 175-degree coverage at 2 kHz ensures uniform sound distribution across the area. The speaker's quality transformer is rated for 100V, 70V, and 25V, with selectable taps of 5W, 2.5W, 1.3W, and 0.7W, providing flexibility to suit various installation and power requirements.

This ceiling speaker is built to last, with a durable zinc-plated, cold-rolled steel grille that complements its clean white finish. The system is suitable for use in air handling spaces, meeting safety standards including UL1480, UL2043, and NFPA 70. With a motor mass of 200 g and an installation depth of just 3.7 inches behind the grille, the CSS8004 is compact and easy to integrate into a wide range of environments, ensuring reliable performance without taking up much space. The speaker's low weight of just 1 lb (net) and 2.8 lbs (shipping) make it easy to handle and install.
