My 5.2.4 setup bass (20Hz to 150Hz) after tuning with Dirac Live Room Control (standard EQ, same as Audyssey, YPAO or ARC)
Same setup after tuning / calibrating with ART:
I don't believe this kind of result is even close to possible with traditional EQ systems (regardless of brand!) - Dirac ART is bringing something new and quite different to the table.
For those unfamiliar with waterfall charts - this is showing frequency/amplitude as well as time (in ms) - so it shows the frequency response, but also the decay generated by reverb in the room - it quickly highlights modes/nodes as well as less persistant decay issues.
P.S: measured using REW with a UMIK1 calibrated measurement microphone - at home on my setup.
