I got a set of 5.1 ultras as a gift and i just bought a set for myself and its too late to cancel my order. So im gonna use them as ht speakers. How do i connect the subwoofer to a HT reciever. I assume I would have to buy some kind of adaptor, but would i loose any sound quality or responce. Or the other choice would be to buy the creative audio decorder which they have at newegg here. I basically would just have my xbox hooked up to play dvds and games.
