My venerable Logitech Z680′s woke me from my heat induced slumber yesterday. A huge thump and crack from the speakers, and then – silence. Blown fuse on the sub. Pants – I hope it is only the fuse & not anything more serious. They are great speakers. But, hey – if they have died at least I have an excuse to buy a new set. Manic searching, no fuses in the house, so eBay – £2.48 for 10, delivered. eBay is the dog’s danglies.
