Unlike conventional subwoofers, which rely on a diaphragm to push air, a rotary subwoofer generates bass using both rotational and linear forces. It operates like a fan, with rotating blades whose angle is modulated by the linear movement of the voice coil of a speaker. Air waves are only produced when the blades are tilted, creating pressure variations that efficiently generate ultra-low frequencies.
A rotary subwoofer is the only type of subwoofer capable of producing frequencies as low as 1 Hz, which falls below the range of human hearing (20 Hz – 20 kHz). Instead of being just heard, these infrasonic waves cause materials and entire spaces to vibrate, much like the deep tremors of an earthquake or the resonance of a massive pipe organ.
To maximize its effect, the rotary subwoofer is mounted to a window, using the outside air as an infinite baffle—a concept that transforms the environment into an endless resonance chamber.
Recurring infrasonic bass patterns taken from various genres are played through the rotary subwoofer to enhance the physical perception of the bass.
