Earthquake’s SLAPS Passive Radiator

SLAPS lets Earthquake subwooofers go very low without having to increase enclosure volume. SLAPS can be used in car as well as in home-audio applications. Wherever subwoofers must be tuned to a low frequency without increasing the enclosure volume, and without the need to deal with the traditional shortcomings of port tuning such as port noise, port length, and availability.

Earthquake’s Overdrive
Overdrive is a patented feature that allows the Supernova amplifier to generate maximum output with virtually any level of input audio signal.

Earthquake’s Optical Distortion Limiting Circuitry (ODL)
ODL was created to eliminate audio amplifier input stage clipping without distorting the audio signal.
