QSC AC-C8T-nb AcousticCoverage 8 Inch Ceiling Speaker (No Back Can)
The AC-C8T-nb is the no-back-can version of QSC's larger AcousticCoverage ceiling speaker, dropping the sealed enclosure of the standard AC-C8T for jobs where the ceiling cavity provides the volume or a full UL-listed backcan isn't required. It carries the same 8 inch driver for wider low-frequency extension than the AC-C4T-nb, with 130 degrees of conical coverage.
A 70/100V transformer with an 8 ohm bypass sits behind the grille, and the plastic C-ring and tile rail hardware installs the same way as the standard model, making it a straightforward swap wherever code and ceiling type allow it.
