On the new 2021 iPad Pro 12.9 the speakers are a more oval shape rather than round, has anyone noticed a difference in sound?

Yes, reviewers say that they have more bass.

I’ve come from the 9.7 iPad Pro, can anyone confirm if this is the same for the 2021 11 inch model?

Sure? I heard the opposite, less bass and lower volume on the 12.9" iPP.
