Found this on Dirac manual but nothing on DDRC-24 manual.Don't understand why Dirac corrected from 10ms to 28ms my speakers response?



"The impulse response measures how a transient such as a drum beat is reproduced in the room. Reflections, diffraction, resonances, misaligned drivers, etc., combine to smear out the transient. As the name indicates, the impulse response shows how the system and room responds to an impulse input signal. An ideal speaker adds no ringing, coloring, or time smearing to the recording, so its impulse response should look just like the input impulse. The similarity between the different loudspeakers’ impulse responses at the listening position affects the perception of stage and image. The more similar the impulse responses, the more easy it is to trick the brain that the loudspeakers are not really there, and that the sound emanates from a virtual stage spanned by the physical speakers. The performance of Dirac Live® is quite unique in that it is so successful in making the system response resemble that of an ideal speaker. This is thanks to robust design of so-called mixed-phase filters. The result of applying Dirac Live® can be viewed in the Dirac Live Calibration Tool™, by clicking the IMPULSE button in the Filter Design tab."

This is just the delay that is needed for the Dirac Live processing. It's not a "correction" per se.
