CSA140Z + ROCKSLIM 70B 2-Pack

The JBL CSA 140Z amplifier and a pair of Rockville Rock Slim 70B black wall speakers give restaurants, hotels, and retail stores a low-profile sound system that disappears into the wall instead of standing out. The 40W amplifier accepts 100 to 240 VAC through its universal power supply, and Crown’s DriveCore technology keeps the one-rack-unit chassis fanless and quiet. Illuminated control rings and a built-in RJ45 port for an optional JBL CSR-V controller complete the front panel.

The Rock Slim 70B speakers use a 5.25" paper cone woofer with a 0.5" mylar dome tweeter, and the mounting bracket is molded directly into the cabinet, so hanging one is as easy as hanging a picture frame. Recessed spring-loaded terminals and a molded wire groove hide the cabling completely behind the speaker for a clean finish on any wall. A rear switch selects 4W or 8W of 70V power per speaker, giving you enough range to match a quiet hallway or a livelier dining area from the same amplifier. Because the system runs on the 70V standard, wiring can run long distances without losing volume, and additional 70V speakers can be added to the line later without changing the amplifier.
