Earthquake's designer, Joseph Sahyoun, created an entirely new design, the Symmetrically Loaded Audio Passive System (SLAPS), that is said to solve both problems.The SLAPS passive radiator eliminates the need for a metal basket, and produces a device whose movements forward and back are symmetrical.It uses two flat diaphragms back-to-back, spaced by about an inch.Each diaphragm is composed of a special multi-layer polyether draw material that combines flexibility with strength, and uses a large-diameter (1.75 inches) roll in its surround material so that it can move the necessary 2 inches to produce a clean 15Hz.
The passive radiator is tuned to 17Hz , a full octave below the sealed cabinet's resonance point.This is said to eliminate most of the problems associated with a ported design.
