JBL CSS-1S/T - 60W 5.25-inch Passive 2-Way 70V/100V Surface-Mount Loudspeaker with 120 x 120-Degree Coverage in Black Finish

The JBL Professional CSS-1S/T is a compact, versatile 60W 5.25-inch 2-way surface-mount loudspeaker, engineered for distributed audio systems or direct 8-ohm applications. Designed with flexibility and durability in mind, this black-finish speaker is perfect for a range of commercial environments such as retail spaces, restaurants, educational facilities, and offices. The CSS-1S/T features a 5.25-inch low-frequency driver and a 0.75-inch polycarbonate dome tweeter, delivering clear, full-range sound with excellent speech intelligibility and balanced music reproduction. The speaker's 120° x 120° coverage ensures even sound dispersion, making it suitable for both background and foreground music or paging systems.

The CSS-1S/T includes a multi-tap transformer, enabling use with 70V/100V distributed speaker lines. Tap settings of 10W, 5W, and 2.5W (70V only) provide flexible power options, while the 8-ohm direct mode allows for standalone operation in traditional audio systems. A rear-mounted switch makes it easy to adjust tap settings. With a frequency range of 85 Hz to 18 kHz and a crossover frequency of 4.3 kHz, the speaker provides a broad audio spectrum, ensuring clarity and depth in both music and voice applications. The 60W power capacity and a maximum SPL of 106 dB (8-ohm mode) or 96 dB (10W setting) deliver ample volume for various installation needs.

The CSS-1S/T's rugged polypropylene structural foam enclosure is designed for durability, while the included ball-type wall-mounting bracket allows for versatile placement and precise aiming. The speaker can be mounted on walls, positioned straight out, or angled for optimal coverage. Its flat-bottom design also allows placement on shelves or other surfaces. Compact dimensions of 9 x 6.3 x 5.6 inches and a lightweight design of 4.5 lbs make the CSS-1S/T easy to install and integrate into any environment.
