Beolab 28 bass “boomy” after theater integration

[Adrian D.]

I started my B&o journey in June with a pair of Beolab 28s. They sounded amazing. Bass was punchy, quick, and a higher volumes a bit much but still enjoyable.
Initially they were just setup as a pair hardwired into each other, and then directly into router.
All my music was played through AirPlay.

Fast forward to yesterday, I setup the Beosound Theater.
The 28s are daisy chained into the theater port 3 as DPL.
I have three listening positions configured, all from the same place and room configuration.

1. Beosound Theater alone
2. Beolab 28s alone
3. Theater as center and 28s as left and right.

The theater alone sounds good but thin compared to the wide stage of the 28s
The ensemble sounds great in movies.
The 28s sound great in stereo all the way to the bass where the issue now I’m experiencing.

Up to a middle listening volume the bass is audible and can be felt in the floors.
But as you move past the 60-70% volume, the bass just sounds boomy and flabby (if that makes sense) where before it was just solid.

Any ideas what could be causing this?
The room sense is now done with the microphone rather than my phone as was with beolab 28s alone.

Settings:
Loudness is off, level is 0
Sound is set to Neutral Music with bass management off, processing direct, compression off.
And I’ve run roomsense multiple times to make sure it wasn’t some issue.
I’ve also toggle temporarily disable room correction to see difference, and it makes it even worse.

im wondering if its cross over? or levels? but not sure where to begin with these settings.
