The QSs sure do keep surprising. I was watching a Stargate episode from a few years ago (off DVD) where there were a lot of construction noises going on in the background.

Three times I got up and walked around the basement because I was sure the dogs were getting into trouble somewhere (from the noises). None of the sounds were even remotely close to where the QS8s were mounted -- you may remember that one is mounted way high on a close wall and the other is perched about 15' away on a pair of soup cans -- I had to replay that section of the DVD a couple of times before I believed the sounds were coming from the surrounds.
