Default [Q] Hardware Question (Speaker)

Good Afternoon,

This is my first time posting on a forum of any kind so please forgive any mistakes i make.

I recently purchased a Galaxy Tab 7.0 after exchanging 5 of them with Best Buy due to a screen defect (Dust under glass and stuck pixels). I am noticing that when the speaker is at full volume the some higher pitched sound sound tinny. I wanted to ask so fellow owners if this a just an issue with the quality of the speaker across all devices or if my device specifically has a issue. I will attach a sound clip of the issue or concern (but i doubt will be of any help).

Thank you to all !!!!!!!
