Qsc Llc AD-C.SUB-BK In-ceiling Subwoofer 6.5 Inch

Product Description

The QSC LLC AD-C.SUB-BK is a 6.5-inch in-ceiling subwoofer designed for low-frequency reinforcement in commercial and residential distributed audio systems. Finished in black, it mounts flush into a standard ceiling cavity and integrates with multi-zone audio infrastructure. Licensed AV integrators and commercial sound contractors are the primary installers. The subwoofer handles low-end extension for in-ceiling speaker arrays where satellite speakers handle mid and high frequencies, delivering a full-range listening experience in a low-profile, out-of-sight form factor.

This unit is suited for commercial installations such as restaurants, retail environments, hospitality spaces, and conference rooms, as well as high-performance residential media or listening rooms. The in-ceiling form factor keeps the subwoofer architecturally discreet while providing dedicated bass support to complement distributed loudspeaker systems. It ships as a single unit and is intended for professional installation as part of a larger audio system design.

Installation Notes

Installation should be performed by a licensed AV integrator or commercial sound contractor familiar with distributed audio system design and local building codes. Power down or de-energize the amplifier or audio system before making any wiring connections. A hole saw and drywall saw are typically required for ceiling cutout preparation. Ensure the ceiling cavity has adequate depth and clearance before mounting.
