Pump-12 – A Unique Passive Radiator Module

Essentially two horn loaded 12-inch passive radiators, the PUMP-12 adds diverse implementations possibilities to our existing lineup of SLAPS passive drivers.

Earthquake’s Passive Radiators provide additional bass, without additional amplifier power or enclosure volume. Formulated to perfectly complement all good quality long-throw woofers on the market. SLAPS/Pump-12 add up to +6dB of bass compared to regular sealed and ported enclosures. They can be integrated into virtually any sub/ cabinet combination.

When using a sealed enclosure, there is one peak of resonant frequency at which the amplifier draws the least current. The graphs below illustrate the difference between a typical sealed box enclosure and the PUMP-ed box enclosure.
