Vaddio Ceiling Speakers are sold and packaged in pairs and optimized for easy installation and accurate voice reproduction. Ideal for conference rooms and classrooms. The Vaddio Ceiling Speakers accurately reproduce audio from presentations and conference calls and are optimized so voices sound clear and natural. The 2-way speaker is built with a specially designed coaxially mounted cone tweeter and a high-performance 4″ metalized cone woofer with a rubber driver surround for long-lasting use. The flush-mounting speakers can be installed in the ceiling or wall and come with a lightweight ceiling tile brace. The air-sealed steel enclosure features a recessed cable cavity and a removable phoenix-style plug. Removing the magnetic, neutral white metal grille reveals convenient baffle-located screws to secure the swivel-out mounting tabs.
