"Alan (Langford, of DEQX) let me A/B three options: the original passive speaker; the speaker with the digitally implemented crossover with DSP correction of the individual drive-unit aberrations; and the whole megillah, with digital crossover, DSP driver correction, and DSP room acoustic correction.

The digital-crossover version lost a slight hooty coloration, and the completely corrected version sounded as though it had an extra half-octave of bass extension and more width and depth to a better-defined soundstage. Color me impressed."
