My iPad Pro 11 inch speakers are really tinny

Hey guys, I just purchased an iPad Pro 11 inch. And I really love it, except the speaker quality is not that good. The speaker sound really tinny and almost aluminum like. I’m coming from a 2017 iPad Pro and the speakers were awesome. Apple has already replaced my original iPad Pro 11 because it was really bad, the one I have now is better but it’s still not that good. Does anyone have any suggestions? Should I return it once more and try once again? Or is Apple just tuning the speakers to be more treble and tinny? Thanks!
