I'm pretty sure it's the same speaker as used in a few previous models. There should be some fairly cheaply on eBay from time to time; I know it's not that imperative, but the G36 is of that age and getting harder to find in nice condition. Personally, I'd just wait for an original to come my way so the deck is as it should be in future, I doubt you'll be using that speaker much for playback in the meantime.
