One speaker wired incorrectly

My GPD Win 2 arrived and there is a manufacturing fault with the front speakers.
One of them has been wired incorrectly. The result is that the two speakers phase-cancel each other resulting in weird sound.
Covering up one of the speakers helps but this is really not good.

How can this be repaired?

Thanks
John

Can you post a video with this sound cancellation in action?

I have the same problem.

Sound test

"正相" = normal
"逆相" = reverse

If your GPDWIN2 sounds normal in "逆相", your L or R speaker is reverse connected.
