James Loudspeaker QXC620 - QX Style 6" Ceiling Subwoofer

Product Overview

The James Loudspeaker QXC620 is a QX-style 6-inch in-ceiling subwoofer engineered for concealed low-frequency reinforcement in residential media rooms, home theaters, and commercial AV spaces. As a passive in-ceiling subwoofer, it installs into the ceiling plane to deliver bass while keeping a clean, low-profile architectural appearance. The QXC620 brings integrated subwoofer output to rooms where floor or wall placement is not practical.

Product Description

The QXC620 mounts into the ceiling and uses a 6-inch driver to add low-frequency support without a visible floor-standing or in-wall enclosure, making it suited to spaces where the ceiling is the cleanest location for bass. It integrates with the broader QX ceiling subwoofer family and can be paired with a matching toe-kick grille style such as the TK4S-QXC620 when used alongside Powerpipe installs. Because it is a passive subwoofer, it requires external amplification, giving the integrator control over crossover, level, and routing within a distributed audio or dedicated theater rack.

It sits in the QX ceiling subwoofer range alongside larger models such as the QXC8S and QXC10S families. For the full lineup, see the James Loudspeaker collection.
