CSA 140Z Commercial 70V Amplifier + (4) 6" White Ceiling Speakers

The JBL CSA 140Z amplifier and four Rockville CCL6T 6" white ceiling speakers put a full multi-room sound system in one order for restaurants, offices, schools, and retail spaces. The 40W amplifier’s universal power supply takes 100 to 240 VAC, and Crown’s DriveCore technology keeps the single-rack-unit chassis fanless and quiet enough to sit behind a front desk or in a back office. Illuminated control rings make the volume and tone knobs visible even in a dim equipment closet, and a built-in RJ45 port is ready for an optional JBL CSR-V wall controller.

Each CCL6T speaker carries a 6" double paper cone woofer and a rear tap switch set to 2.5W, 5W, or 10W, so the same four speakers can be tuned louder for a busy dining room and quieter for a hallway or restroom on the same amplifier. Because the system runs on the 70V standard, cable runs can stretch across a large building without losing volume, and additional 70V speakers can join the line later. A fireproof screw terminal block adds a safety margin, and the paintable flush-mount grille keeps ceiling cutouts looking finished in any space. The result is a ready-to-install package for anyone who needs even coverage across several rooms without piecing together separate components.
