My dad recently recieved a pair of speakers from a company called "London Audio". Never heard of them but then again I am not a real hard core audiophile. My dad couldnt tell me much other than they appear to be 6-8 ohm bookshelf speakers.

Any advice best way to set these up for optimal performance. They are currently hooked up to the Sony reciever that came with a Sony HT (model 660 I think??) set up.
