Product Overview

Overview

The QSC AD-C4T-LPZB is a low-profile version of the 4.5-inch zero-bezel ceiling loudspeaker, only 100 mm deep. It is for ceilings with little space above them: a shallow back can that sits just 100 mm above the tile, with the same frameless grille, DMT waveguide and tuning as the deeper AD-C4T-ZB. The trade-off is a larger 245 mm cut-out to fit the wider, flatter enclosure.

Frequently Asked Questions

What is the QSC AD-C4T-LPZB?
The QSC AD-C4T-LPZB is a low-profile version of the 4.5-inch zero-bezel ceiling loudspeaker, only 100 mm deep. It is for ceilings with little space above them: a shallow back can that sits just 100 mm above the tile, with the same frameless grille, DMT waveguide and tuning as the deeper AD-C4T-ZB. The trade-off is a larger 245 mm cut-out to fit the wider, flatter enclosure.
When should I choose the low-profile model?
Choose it where the void above the tile is too shallow for the 176 mm-deep AD-C4T-ZB. It is 100 mm tall overall.

Q-SYS lists the same 70 Hz to 20 kHz range, 150 degree coverage and 102 dB continuous SPL, with 87 dB sensitivity against 87.5 dB.

A 245 mm (9.65 inch) circular cut-out, larger than the 195 mm of the standard ZB. An AD-MR6 mud ring is available for pre-install.
Can I get a black grille?
