Qsc Llc KLA12-BK 2-way Passive Loudspeaker 500W

Product Description

The QSC LLC KLA12-BK is a two-way passive loudspeaker rated at 500 watts, finished in black. Passive loudspeakers in this class are driven by an external amplifier and deliver full-range sound reproduction across two drivers: a high-frequency tweeter and a low-to-mid woofer. The KLA12-BK is suited for professional audio reinforcement applications where a separate amplification source is already in place. Installation and integration are typically handled by licensed audio-visual or sound system contractors working within standard low-voltage wiring practices.

This loudspeaker is appropriate for fixed-installation and portable sound reinforcement scenarios, including stages, houses of worship, event venues, and similar professional audio environments. The unit ships as a single piece and is categorized as a passive loudspeaker, meaning it requires an external amplifier matched to its 500-watt power handling. The black finish suits a wide range of venue aesthetics.

Installation Notes

Installation should be performed by a qualified audio-visual or sound system technician familiar with professional loudspeaker systems. Ensure the driving amplifier output is powered down before making speaker connections. Match amplifier output impedance and power rating to the loudspeaker specifications to avoid damage. Observe applicable low-voltage wiring codes and rigging safety standards when mounting or flying the enclosure.
