"...One
other breakthrough has occurred rather quietly on the sidelines
- the DEQX approach to phase-correct DSP-based crossovers
with up to 300dB/octave slopes. These digital networks sport
embedded room-correction and Preamp functionality and
are available as pre-corrected OEM modules for speaker manufacturers.
Jeff Rowland used DEQX at CES 2005 as did Magico. Ditto
for NHT and Overkill Audio....I've
now heard from numerous highly placed sources in the audio
engineering world that their DSP board must be considered
the current state-of-the-art bar none."
"The
great opportunity which currently presents itself to the
loudspeaker market is "infinite slope" digital crossovers
and phase, time and frequency correction....the
advantages inherent in the DEQX solution mandate a close
investigation by any loudspeaker engineer who is truly serious
about perfecting the art."
