The launch of the Gravity 30 marks a 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 officially released the Gravity 30. The new subwoofer 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 significantly reduces 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 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 as 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 and feature transducer protection, with thermal and excursion limiting. The touring model incorporates an integrated rigging assembly, allowing up to 12 cabinets to be suspended, and features automatic array detection - using specially developed built in IR sensors - allowing quick and seamless set up of subwoofer arrays.
Specifications for the impressive subwoofer design detail an operating frequency from 25Hz to 90Hz. Audio inputs are balanced XLR / 14 pin Amphenol connectors, while power is supplied using Powercon IP65 TRUE1 locking cables to the built-in auto-switching 100 - 250V power supply with 1560W AC power consumption. Construction uses high-grade void-free Baltic birch with a tour-grade high-impact EXL Polyurea finish, resulting in a cabinet weight of 125kg / 275lb (150kg / 330lb w/rigging hardware).
