Those very small speakers only work 'reasonably' when they are in a well formed case mostly like a caving in a pc monitor or the housing of laptop. That takes care of the bad frequency respons in open air.
That makes sense after my experience. Unfortunately the data sheets don't mention any such thing. I guess you assume you just have the domain knowledge for this. That's ok though, I can change to an old style larger paper cone speaker. There's enough room on the 3D printed front panel to allow for it to be mounted next to the PCB. This will have the added benefit of freeing up some badly needed room on the PCB itself.
