John Atkinson and Kal Rubinson became familiar with DEQX, an Australian company specializing in digital loudspeaker correction and room compensation, during their review of
NHT’s Xd active loudspeaker system; I had the opportunity to become acquainted with DEQX at last year’s
Rocky Mountain Audio Fest.
Then, the company gave an impressive demo of their HDP-3 standalone processor mated to a pair of Gallo Reference loudspeakers and Parasound amplification, showing room interaction and examining how the sound of the system could be optimized in the frequency, phase, and, most important to DEQX,
time domains.
This year, the company gave a similarly impressive demonstration of their new HDP-4 processor ($4995), which should be available in about two months.
