The Gravity 218 is a high-output, low-frequency subwoofer. Utilizing Integrated Powered Adaptive Loudspeaker (IPAL) technology to achieve exceptional tonality and low distortion. This space efficient low frequency module dramatically increases output per cubic volume compared to traditional dual 18” loudspeakers. The unrestricted vent ensures non-turbulent streamlined airflow, eliminating port noise and increasing output. An 8,000-watt class-D amplifier provides efficient high output power to two high-excursion 18” transducers.

The Gravity 218 is cardioid arrayable, providing the maximum amount of flexibility when creating large subwoofer arrays, especially when a high amount of directionality is required. The subwoofer is available in both touring and installation versions. Both models integrate seamlessly with PK’s Kontrol™ software, enabling remote access to key DSP features and real-time monitoring. Automatic-Array detection utilizes the module’s built-in IR sensors to quickly map the cabinet positions in Kontrol™ for a quick and seamless setup of subwoofer arrays. The touring model incorporates an integrated rigging assembly, allowing up to 12 cabinets to be suspended when coupled with custom flybar.
