Definitely lacks subwoofers or at least feels like it. There’s no omnidirectional bass feeling. It’s all coming from the front doors.I wish the system would adjust to which way you like it. To me it gives out more treble and less bass. I have a 2014 GX and that baby thumps so I have a really good comparison and the new GX sucks with and lacks bass. Yea, I turned off surround and did all the techy details with no avail. I feel it lacks sub woofers
I’ll say that in home audio Mark Levinson products are often associated with reference sound, which is supposed to be very “accurate”. More accurate does not mean more enjoyable.
