Found this:
"The enclosures are three-way systems using components custom-designed and manufactured to Sonics' specifications. Sonics combines four low-frequency loudspeakers in each cabinet with nested high- and mid-frequency horns. McCroskey points out the trapezoidal dispersion pattern (narrower at the top than the bottom), designed to match the distinctive shape of IMAX theaters. Using a sub-bass system for the deepest lows, McCroskey says, minimizes phase coherence problems. "In most installations, we use eight sub-bass loudspeakers, each in a 16-cubic-foot enclosure," he says. "The enclosures include a filtering labyrinth we designed that physically traps the higher-frequency components that can otherwise cause overtones and distortion."
