Avalon Acoustic Center and Subwoofer speaker system. These were part of my home theater system. They were purchased in 2006 and used very lightly for less than 3 years. We sold our home and kept them in temp controlled storage thinking we would own another home with home theater room; we never did so we're selling. The Symbol Subwoofer has a 500 Watts at Load internal amp, 2 RCA and @ XLR inputs. We ran the center channel with a McIntosh MC-501 Amp. Also for sale, see listing.
