Actually, I did mean "old." I also specifically said "when surround sound systems became popular in the consumer space." I have no doubt that you guys have older "surround" systems, but I highly doubt they were considered "popular" at that time. The sound system I'm working with at the moment couldn't be more than 10 years old, and by then they should have known better, particularly if they knew enough to wire the entire first floor of the home for sound.
