If your audio stops working and you feel it might be a speaker issue, you may be able to find similar, suitable speakers on Amazon or other marketplaces. The speakers are USB powered and use a standard 3.5mm headphone jack so any speakers you find that will fit into the marquee area should be fine.
But if you'd prefer the brand we use then you can order them from us directly. They will come with the mounting brackets already in place.
