The Gravity 30 sets a new standard for low frequency reproduction with unprecedented output capability and exceptional transient accuracy. With a very high output-to-size ratio, the Gravity 30 replaces three conventional dual 18” subwoofers, significantly reducing truck pack and weight. A 15,000-watt class-D amplifier with differential pressure loop technology provides efficient, high output power to the 30” moving magnet linear motor M-Force transducer. The dual reflex bandpass enclosure provides high, symmetric loading to the cone increasing efficiency and dramatically improving transient response, reducing distortion and maximizing low frequency extension.
A precision-engineered steel alloy motor mount provides a rigid connecting assembly which acts as large heatsink for the transducer and a grill for the high frequency chamber, dramatically increasing power handling and reducing power compression. The meticulously engineered assembly is a result of more than two and a half years of development, including PK’s 1,000-hour continuous maximum output test to ensure long term reliability.
The Gravity 30 is cardiod 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 providing access to key DSP features and real time monitoring. The touring model incorporates an integrated rigging assembly, allowing up to 12 cabinets to be suspended, and features automatic array detection allowing quick and seamless set up of subwoofer arrays.
