MacBook speakers

[NDA]

For some reason I cannot fathom (not loud music or anything) the right hand speaker in my MacBook Air has blown.

Are these replaceable items?

It's been fault free since 2013, and still just as fast as ever, so repair would be preferable to replacement.

I doubt it could be some other issue.... could it?

Have you tried headphones to check both channels are working?

Yes all working absolutely fine on headphones.... but the right channel sounds totally blown through the speakers.
