JBL CSA 2120 Commercial Amplifier Amp+8) White Ceiling Speakers 4 Restaurant/Bar

The JBL CSA 2120 amplifier and eight Rockville HC55-16 white in-ceiling speakers give larger restaurants and bars full-room coverage without a single bulky cabinet speaker in sight. The two-channel amplifier delivers 120W per channel into 4 or 8 ohm loads, is plenum rated to UL2043 for ceiling air-handling spaces, and runs silent thanks to convection cooling with no fan. Auto-standby mode cuts power draw during closed hours, and summing RCA inputs on each channel keep source hookup simple.

Each HC55-16 speaker uses a 2-way design with a 5.25" polypropylene woofer and a mylar dome tweeter, handling 60W RMS and 150W peak per speaker for clean mids and bass with crisp highs. Rubber surrounds cut down on distortion at higher volumes, and an aim-able swivel tweeter lets you angle the high end toward the seating area below. Eight speakers wired to one two-channel amplifier is enough to fill a large dining room or split evenly across two zones, with spring-loaded push terminals making the wiring straightforward. The flush-mount grille and 16 ohm design let multiple speakers share a single amplifier channel without overloading it, which keeps the whole install to one amplifier instead of several.
