Just to add a little to this topic, I rearranged my room and moved my speakers out further to get closer to the "typical" placement formula, and wow! I don't know if the doping gave more coherent phase info or what, or maybe it was just the placement diff, but the soundstage now is incredible! I played Madonna(Immaculate Collection) and the soundstage now ranges from about 6ft behind the rear wall to about 4ft in front of the speakers in depth, and about 4ft outside each speaker in width! This is about 13ft depth and about 20ft width. And the imaging is rock solid, well to the outside of the speakers. With this kind of depth, who needs surround sound? I know I'm raving, but I am flabbergasted. Really, guys, this is the first time I have ever gotten soundstage and imaging like that from a speaker. Oh, sure, you get imaging, but alot of times it is centered and smallish. And, you get big soundstage, but the image focus is lacking, but the combination of both is a real mind bender. And, having the speakers disappear while providing solid imaging thet's well outside the left and right boudaries that is "palpable", is alot different than having the speakers disapper and provide nice imaging within the left/right boudaries.I suppose this is why people spend $30k-50k on a set of speakers.Pardon my lunatic rantings, but I am really enjoying this. I feel like after all the speakers I built, I finally hit the bullseye.
