I calibrated online Dirac Live withon an Arcam AVR850 for a customer with Bowers & Wilkins 804 D3’s, HTM2 D3 center channel, and the new REL 212/SX subwoofer.


I used Dirac to take measurements of the speakers and the REL subwoofer which was connected via a high level and LFE connection. I could see something was not quite right so I made some settings suggestions to change on the REL so it would better integrate with the speakers. I then calibrated the system to maximise its sound quality.

Terry was great to work with (answers all your questions) and really has a great understanding of how the Dirac calibration works. It made a significant difference to my system. I highly recommend using his services!
