The Purpose of This Subwoofer Shootout

The purpose of this subwoofer shootout is simple: compare products for performance using measures and techniques as defined by the CEA 2010 standard. The CEA 2010 standard is a means for measuring the maximum output of subwoofers at the two lowest audible octaves, 16-32 & 32-63 Hz. Unlike a traditional harmonic distortion number, the CEA number attempts to weight different harmonic distortion components based not only on their amplitude relative to the fundamental, but on their separation in frequency as well.
