AD-C820R/S | AD-C821R/S
The AD-C820R/S and AD-C821R/S (R for Round Grille and S for Square
Grille) loudspeaker systems are designed for ceiling mounted loudspeaker
applications requiring high SPL output. The AD-C820R/S Systems ship with
the AD-C800BB backcan and are perfect for pre-installed applications. The
AD-C821R/S Systems incorporate a fully integrated, factory sealed enclosure
and use “dog-ear” style mounting - perfect for blind mount installations. Both
models also include a set of tile rails and C-rings to complete the installation.
