CSA280Z Amp + (4) WET-40W White Wall Speakers

This 70V bundle puts background music and paging inside and outside the same business with one order: a JBL CSA280Z two-channel commercial amplifier and four Rockville WET-40W 4" wall speakers in white. It suits restaurants with a patio, bars with an outdoor deck, cafes, retail shops, and gyms that need sound in spots a ceiling speaker can't reach. The CSA280Z puts out 80W per channel with 70V and 100V outputs built in, so you can run long speaker lines from a back office to the dining room and out to the patio without working out impedance. Its fanless 1U chassis stays silent on a shelf or in a rack with the included mounting kit, the universal power supply accepts 100 to 240 VAC, and Energy Star certification keeps running costs down for a system that plays all day.

Each WET-40W is IPX55 rated, with a waterproof ABS cabinet, a rustproof aluminum grille, waterproof spring-loaded terminals, and powder-coated steel brackets that pass a 96-hour saltwater spray test, so rain, sun, and dust aren't a concern on a patio or pool deck. The 360 degree ball joint bracket lets you aim each speaker at the seating area once it's on the wall. A 4" polypropylene woofer and 13mm PEI tweeter in a sealed cabinet cover 70Hz to 20kHz for clear vocals and balanced music. A tap switch selects 20W, 10W, 5W, or 2.5W per speaker, so the bar can run louder while the entrance stays low; with all four tapped at 20W, the load is half the amp's total output. The amp's RJ45 connectors also accept JBL CSR-V wall volume controls (sold separately), giving staff level control from the floor.
