Earthquake - PUMP12 - Dual Passive Ported Module

Earthquake Sound's new PUMP-12 passive radiator module, designed and patented by Joseph Sahyoun, the company's president, is essentially two, horn loaded, 12-inch passive radiators in a single unit. With many different applications and uses, the PUMP-12 is designed to add up to +6dB of bass without any need of additional input power when installed in a sealed enclosure. As the Californian company details, the PUMP-12 design features a horn loaded neck with anti-rocking dual suspension system that increases speaker impedance. When used in a sealed enclosure, there is one peak of resonant frequency at which the amplifier draws the least current.

The company's previous SLAPS technology was patented years ago and it was a first in the industry, providing additional bass, without additional amplifier power or enclosure volume, and featuring user-tunable adjustments. Now, the company follows up with what is basically a double SLAPS in one single unit. The Pump 12 increases the SPL at low frequencies while maintaining a small enclosure. With a piston area of 226 sq.in. (0.1458 m2) and cutout dimensions of 5-1/2" x 12-3/4" (140mm x 324mm), the new passive radiator module can improve a speaker box response regardless of the application, including home audio, car audio and professional audio.
