Announcing the release of Gravity 30

The launch of the Gravity 30 marks an significant milestone for PK Sound as its first 30” subwoofer and the first product released in the Gravity family. After years of research and development followed by over 1000 hours of continuous maximum output testing, PK Sound is proud to officially release the Gravity 30 today.

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, dramatically improves 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, additional cooling dramatically increases power handling and reduces power compression.

PK Sound CEO Jeremy Bridge says “We’ve spent a lot of time in R&D with Gravity to ensure that it exceeds the expectations of what a standard subwoofer provides. We weren’t interested in creating just another sub—we aimed to deliver something that will raise the bar. The differentiating factor is not just its high output, but its clear and transparent sound. Further to that, it has exceptional weight to output ratio and transient response. I am extremely pleased with the final product. I can confidently say that once you experience it, your perceptions about how a pro-audio subwoofer can perform will change forever.”

The Gravity 30 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 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 and sub wall detection allowing quick and seamless set up of subwoofer arrays and sub walls.
