CSA2120 Amplifier + (4) D4-8 Black Wall Speakers

This JBL and Rockville package gives restaurants, bars, retail floors, and patios a complete background music system in one order: a two-channel commercial amplifier and four wall-mount speakers matched to run together. The JBL CSA-2120 delivers 120W per channel at 4 or 8 ohms and stays stable from 2 to 16 ohms, so you can wire two of the 8 ohm Rockville D4-8 speakers on each channel and cover a dining room and a patio, or two zones of a shop, from a single compact unit. Summing RCA inputs on each channel accept a mixer, streamer, or media player, and auto-standby mode saves energy during quiet hours. The amp is convection cooled, plenum rated to UL2043 for air-handling spaces, and ships with a rack mounting kit for an equipment closet or bar back.

Each D4-8 pairs two 4" polypropylene woofers with a 1" silk dome tweeter and a 2500Hz crossover for clear vocals and full music playback from 55Hz to 20kHz. The weather-resistant ABS cabinet is built for outdoor patios as well as indoor rooms, and its curved front spreads sound across an 80 x 120 degree pattern so tables near the wall and across the room hear the same mix. A swivel bracket tilts 90 degrees vertically and turns 100 degrees horizontally, letting you aim each speaker at the seating area after it's mounted. Detachable euro-block terminals take ordinary speaker wire, which keeps installation and future changes quick.
