Product Overview
The QSC AD-P4T is a 4.5-inch two-way pendant loudspeaker for open-ceiling commercial spaces that need even foreground or background music coverage without a finished ceiling. Voiced for tonal consistency across the AcousticDesign range, this pendant loudspeaker operates on 70/100V distributed lines or 16-ohm low-impedance circuits. Its 150-degree conical coverage suits retail, hospitality, and commercial meeting spaces with exposed structure.
Product Description

The QSC AD-P4T pendant loudspeaker pairs a 4.5-inch weather-treated woofer with a 0.75-inch aluminum dome tweeter on a DMT waveguide, producing broad 150-degree conical coverage and improved off-axis response for commercial installation. It handles 30W RMS with a peak maximum SPL of 108 dB and a stated frequency range of 65 Hz to 20 kHz (-10 dB). A low-loss 70/100V transformer with 16-ohm bypass and a 4-pole Euroblock connector under a sealable input cover support reliable AV system integration in exposed environments. The UV-treated ABS enclosure resists discoloration, making it appropriate for long-term distributed audio. For a higher-output pendant in the same family, compare the QSC AD-P6T pendant loudspeaker.
