Need help: soundstage?

The magic question. Speaker position is important, but by your measurements it sounds like your placement is pretty good. You can always fine tune placement. Bass is also important to round out images, especially in a large room. Your speakers should be able to fill a 12' x 15' room with some nice sound. The best imaging speakers have been, and are typically monitors. If imaging is a priority to you it seems we may be in the minority. What prompted me to respond was, "are the speakers not good enough to create 3D sound?". Better ($$$) products do not always provide better imaging. I have upgraded components and cables several times and in return for my money I get better dynamics, and sometimes more detail. But sometimes those products collapse the image and I am truly disappointed. More money is not always better when it comes to imaging. Buy components/speakers where the designers are concerned with imaging and not only will you be enjoying a magical system for many years, but in a few years you will own classic equipment instead of the latest, overpriced crap.

Hope this helps.

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.
