So I am dealing with a Bose FreeSpace DS16F system, it has three units connected to a Bose FreeSpace amplifier all contained in a drop down ceiling. It has been connected to an internet raido receiver and has been working for about 20 years but recently some of the speakers would cut out frequently until they all stopped playing one by one. I am going to go up there and poke around but I wanted to see if anyone had similar issues and if they would have any idea what the problem could be.
