Receivers, Amps, and Processors
With stereo mode, DL successfully eliminated a nasty room mode at 42Hz (+18dB).
When switching to other listening modes, the boomy bass was back.
Before crying wolf to Onkyo or Dirac, I would be happy to get your feedback.
Observed on Onkyo TX-NR7100, likely the same with TX-RZ50. Other brands...
