Sorry guys but I'm looking at purchasing one of these and I have but one inquiry before I bite the bullet, how loud are they - I live in a pretty quiet apartment and I like to be able to sleep at night, I assumed given their target buyer that they would be fairly quiet little boxes but was wanting some feedback from users, every review I have read about them just says "yeah it's pretty quiet", I wanna know compared to what and how audible it is from distances, it would be sitting almost directly beside me.
