The nice thing about open baffle bass is it does not carry through walls. As long as I cover the heat/air ducts with throw pillows my wife can sleep peacefully two rooms away with my system playing fairly loud.

I also enjoy listening on my screen porch with my back to the house and facing my outdoor speakers. I can play these loud but the sound does not carry either. If the speakers were mounted on the house facing the backyard the sound would be louder but wouldn't sound as good.
