Description
Equip two ceiling tile locations with full-featured 25/70V lay-in speakers in one order with the Valcom S-522B-2, a two-pack of 2x2 lay-in ceiling speakers with backboxes, volume controls, and white acrylic baked enamel finish for suspended ceiling paging and background audio installations.
The Telecom Spot Expert Review
The S-522B is Valcom's 2x2 lay-in speaker with backbox and volume control — the complete assembly for drop ceiling paging without any additional hardware sourcing. The two-pack format covers a pair of ceiling locations per order, matching the common installation pattern of one speaker per small room or two speakers per mid-size room. The integrated backbox eliminates the separate rough-in step required for standard cut-in ceiling speakers, and no tile cutting is needed — the assembly drops into the standard 2x2 tile opening exactly like a ceiling tile. The front-accessible volume control allows level adjustment from below the ceiling after installation, which prevents having to go back above the tile to adjust a screwdriver-only control. The 25/70V transformer handles both standard speaker line voltages without a separate transformer accessory. White acrylic baked enamel finish matches standard commercial ceiling tile color across typical institutional and office environments.
