My sofa is in the corner of the room. I have a HomePod and Sonos Playbar on a cabinet opposite. The HomePod bass is too much and, for some tracks, totally boomy and overwhelming. The same tracks played through the Playbar also have the boomy bass, although to a lesser extent. However, when the Playbar is tuned using Trueplay the boomy bass goes away. Result. The HomePod never even seems to try to tune to the same extent. A win for Sonos I think.
