I tried the Wilson "WASP" method of positioning the speakers in my room today.
I don't have much leeway in my room and I use the length of the room for a "nearfield" listening setup as it eliminates much of the early reflections due to the toe in of the speakers and allows me to achieve a much greater soundstage that extends from wall to wall.
None the less, after reading the Wilson manual I decided to give it a try. Surprisingly or I guess I should say not surprisingly, it works but I already had the speakers positioned exactly where the experiment lead me. There are not many spots in my room where the speakers work well except a few and I have discovered the "golden placement" for my room many years ago already. Walking around the room talking out loud felt a little weird but what the hell.
Then I asked my son to repeat the same process while I sat in the listening room. That confirmed the same thing I heard. The speakers were already in the neutral zones, optimized and measured to within 1/8 of an inch from the sweet spot and toed in exactly with the tweeters crossing over about 2 feet behind my head which seems to work the best in terms of focus and soundstage width.
Anyone interested in this method and it can be used to position other speakers besides Wilson, here is the link:
