Qsc Llc AD-S.SUB-WH Passive Subwoofer 6.5 Inch

Product Description

The QSC LLC AD-S.SUB-WH is a passive subwoofer loudspeaker designed for low-frequency audio reinforcement in installed sound applications. Sold as a single unit, this speaker handles bass extension duties in distributed audio systems where a separate amplifier or DSP-equipped processor supplies the drive signal. The 6.5-inch driver format suits installations where a compact enclosure footprint is required without sacrificing low-end output. Audio system integrators and commercial AV technicians are the primary installers of this unit.

This subwoofer is suited for commercial and light commercial installed sound environments, including conference rooms, retail spaces, restaurants, and similar venues requiring supplemental bass reinforcement. It is intended to be paired with a compatible QSC amplifier or DSP unit that provides the appropriate crossover filtering and power. Because it is a passive design, no internal power supply or network connection is required at the speaker enclosure itself.

Key Features

• Passive design requires an external amplifier for operation, simplifying enclosure form factor
• 6.5-inch driver configuration suited for compact installed-sound subwoofer applications
• White finish supports unobtrusive integration into finished interior spaces
• Single-unit packaging allows for flexible quantity ordering

Compatibility

Designed as an OEM-style passive subwoofer for installed commercial audio systems requiring a compact low-frequency driver enclosure driven by an external amplifier.

Installation Notes

Installation should be performed by a qualified AV integrator or low-voltage technician familiar with distributed audio system design. De-energize the amplifier and disconnect speaker wiring before making any connections to the enclosure. Follow NEC low-voltage wiring guidelines for in-wall or plenum speaker cable routing where applicable. Verify amplifier output impedance and power ratings are compatible with the speaker before commissioning.
