Hi. Thanks for your replies. I have listened to the Def Tech 800s, but not the Orbs, as they are direct marketed only. The 800s have a very smooth midrange but appear to be somewhat tempermental as far as placement/setup is concerned. Plus, the sub sounds a bit bloated and un-musical, which my ears do not like. I was hoping someone could offer insight into the overall sound of the orbs,whether they are tempermental regarding placement, and if the super8 sub sounds musical or not?
