Loudspeakers are the weakest link in the audio chain, introducing errors and distortion due to their mechanical design. Even an expensive ‘audiophile’ speaker adds roughly an order-of-magnitude more errors and distortion than the signal driving it.
The DEQX Calibrated™ PDC preamp/processor measures the performance of your loudspeaker system, then processes the signal going to the speaker so that it compensates for errors in both the time and frequency domain.
A DEQX Calibrated™ ACTIVE speaker system, where each driver has its own amp and a DEQX active crossover, provides further benefits of High Definition loudspeaker performance:- reduced distortion, higher volume and dynamics, greatly improved dispersion, and much more.
DEQX’s proprietary time domain correction measures the extent that some frequencies lag behind others, a phenomenon known as ‘group delay'. DEQX can then delay, and phase align, the early frequencies so that the later ones can catch up. This results in the sound we finally hear having the same natural time-coherence as is present in the audio signal. Simultaneously, the frequency response is corrected so that the volume of frequencies that the speaker has made louder or softer is also corrected to match the original signal. Again this occurs at hundreds of different frequencies while also correcting phase at all frequencies.
We provide a suite of technologies
which are employed together to solve acoustic problems and improve
the sound of any system. All the technologies complement each other,
and are applied in series to give the best results when listening to
music and home theatre.
Speaker Correction corrects each speaker's
measured full-band impulse response for a flat frequency response,
including phase & time
alignment. Read more…
