Need help: soundstage?


Hi,
I'm new on this hobby, and I would like to know that what exactly do you look for when placing speakers for the best soundstage or in another term when do you know you have best soundstage? How do you set up the speaker in order to have 3D imaging?
For the current set up, I can hear the singer right on the center with instruments on left and right side but everything is flat. If I can bring the singer up front little bit then I'm in heaven.
My room is 147"Wx180"Lx96"H, and my speakers are 60" from back wall and 40" from side wall (Cardas' formular)with toe in. The speakers are JMlab Electra Monitor run with Classe amp. Are the speakers too far from the back wall or are the speaker not good enough to create 3D sound?
Thanks for your help

Hi jfrech, I went to the immediasound.com web site and they had no speaker setup info there. COuld you fill us in on their method?
Onhwy61,
The deepest bass of my speakers can go is 57hz. So, my speakers doesn't have a good soundstage,is it correct? I also have a subwoofer, and I haven't connect it yet. Does the subwoofer help to improve the soundstage? Where do people use to put the subwoofer: front corner, along the side wall or behind the corner of listening chair?
Thanks for your help

The subwoofer will definitely help with regards to soundstage. Locating the sub is a trail and error process, but I would start in the front corner. Don't hesitate to experiment. Ideally, the sub should be setup such that you don't hear it until you turn it off.
I also find the Immedia site a useful different appraoch to the standard cardas set-up technique, I use some ideas I learned there in my system.

Please try this very simple tweak, put vibrapods between speaker and stand and you should hear deeper bass and often
improved 3D effects, only takes a minute to try.

Also you can purchase a TDS Passive Audiophile which also can improve 3D soundstage, cost $400 new or $250 used here.
