Model details
A vented powered subwoofer for KLA arrays and other compatible PA systems. Its onboard processing, polarity control and integrated rigging provisions support a planned system rather than an assumed universal pairing. The 18-inch driver extends low-frequency coverage for live bands and playback, using its internal 1000 W amplifier module. XLR and powerCON connections support system signal and power distribution; flown or stacked use must follow the correct KLA rigging and load instructions.
Typical uses: KLA PA systems · Concert bass reinforcement · Configured ground or flown systems
