After many, many placement adjustments, I have found the only way to get these speakers to image in my room is by toeing them directly into my listening position. They are approximately nine and 1/2 feet apart. Volume has to be moderately high. Now they are imaging beautifully. Rear firing tweeters are turned up just a smidge from being completely off. I've never had a speaker that had to be toed-in like this nor, required such volume to focus the vocals. Is this normal for this speaker? Or, am I still off base?
