Alto TX10 Active Speaker Repair - Unknown component

Hello,

I'm trying to repair an ALTO TX10 Speaker but I can't really find much information online, no schematics or anyone with the same issue.
I've located the faulty component but it's broken and the writing is completely gone. I can't really identify what it is.
I've attached some pictures of the board itself and the broken component.

Can anyone lead me in the right direction?

Thanks for your help
