I own 2 x Arcs.
I was watching walking dead on one of them at nearly 50 % volume which is what I would expect.
I then watched a movie in the living room and volume was super loud even at about 10 - 15% volume.
Because of this the loudness eq makes the bass so loud and over emphasised as it is adaptive at lower volume,
The the only way we could watch the movie was with night mode on in order to hear the dialogue without being blown out of the sofa (Terminator 2 on ATV for info)
I tried walking dead in the living room this am and again this could only be played at a very low volume.
The only difference in the 2 systems is I have a sub mini on the living room system.
Could that be causing the huge volume variation between the 2 systems???
