Qsc Llc AD-C4T-ZB-WH 4.5 in Two-way Ceiling Speaker

Product Description

The QSC LLC AD-C4T-ZB-WH is a 4.5 inch two-way in-ceiling speaker designed for commercial and residential audio distribution systems. It delivers full-range sound reproduction from a low-profile ceiling mount configuration. The two-way driver design splits audio frequencies between a woofer and a dedicated tweeter, improving clarity across the audible range. The white finish blends with standard ceiling surfaces, making it a practical choice for installed audio applications in commercial spaces, hospitality environments, and multi-room residential systems. Installation is handled by professional AV integrators or low-voltage technicians.

This speaker is suited for in-ceiling distributed audio installations where unobtrusive placement is required. Typical applications include conference rooms, retail spaces, hotel lobbies, restaurants, and whole-home audio zones. The ceiling-mount form factor allows for even sound coverage across a listening area without the footprint of surface-mounted or freestanding speakers. It is sold as a single unit and is appropriate for use in networked or zoned audio systems driven by compatible amplifiers or AV distribution equipment.

Verify ceiling construction and joist spacing before cutting the ceiling opening to ensure proper mounting clearance.
