B&W Speaker Placement

I had a similar system and room as what you listed. 1st of all, you need to check speaker placement so that "ALL" speakers are angled towards the "sweet spot". Then you need to setup your speaker config and then adjust the output levels on your Lexicon. Now, in order to do this you will need a "Sound Level Meter" (this can be purchased at Radio Shack). I would have the center channel up at least 3-5 db's higher than the mains. Question: Why don't or aren't you using side speakers? Your Lexicon is setup for a 7.2 (7-speaker, 2-sub) system, if used, this would definitely add to your soundstage, especially with DTS encoded music disc's. Lastly, if you don't have a sub (with your equipment, the Sunfire True Sub would be a reccomendation), this would be very beneficail in getting the soundstage you require. Hope this helps.

Thanks for the response. I do not have a sub or sides. Got to ease the wife into this. The sub will be next.

I have B&W CDM 9NT for two channel stereo. Make sure to have enough room behind the front two speakers. When I moved the speakers from 2ft from the wall to 3ft from the wall, the difference was big. Also, you want to place the speakers as far apart as possible without losing the center image (use female vocal to calibrate), but not too close to side walls or you'll have other problems. Then your listening spot should be about corner of equilateral triangel. Hope this helps..
