Yes, I can see my bass speaker moving too. That does not mean
it is representing the low frequencies correctly.

I am not convinced there is a bug in the opus codec
that would mis-represent the very low frequecies.
At any rate (ha, pun!), the point is moot: I don't care
how well a codec compresses a 10 Hz sound, because
I will never hear it anyway.
