Im remodeling my basement and planning my home theater system. The previous owner mounted 2 10" speakers in ceiling (finished) I pulled speaker covers off but can't see anything as far as brand ect... I also have 2 3way Fisher STV 9015 100 Watt speakers. They always sounded great and louder than anything Ill ever need . Is it possible to add good receiver and some additional speakers and have great sounding system.? Thanks
