yep it does (see below).
i should also point out something interesting i came across in an old download of peter aczal's audio critic. in an interview with the designer from NHT ken kantor, he did experiments placing single audio sources in a circle around subjects heads and found that there is naturally in humans less cross-correlation at certain angles. and he found that that the angle that minimizes it the most is 21 degrees. so if you have your speakers at an equilateral triangle from you (30 degrees) a fun experiment is to move them closer together by 10 degrees and see if that WIDENS your soundstage some.
Some time ago I did a bit of placement experimention and settled on a spot that seem to present the best imaging and soundstage width/depth. Today I did quick calculation (using a triangle side/angle calculator I found online
) which revealed an angle of 23.3 degrees. Interesting how close it is to the 21 degrees you quoted. I did try positioning them to achieve 21 degrees, but it put them right up to the sides of my 60" plasma and too close to the wall behind. This caused some degradation of imaging and depth of soundstage. I should note that because of my room setup (among other things, my seating and TV positions are fixed), I lack a bit of flexibility in speaker placement.
Out of curiousity, I placed the speakers a bit farther apart (about 30 degrees out) with some interesting results. Overall width of soundstage didn't seem that much different overall (it was still very wide), but imaging off to the sides of the speakers was better with the speakers closer together! I would have expected that bringing the speakers closer together would have narrowed the soundstage. I didn't expect that with the speakers closer together that a wide soundstage could be maintained with better imaging within that soundstage.
It would be interesting to hear from someone who has more placement flexibility to see what they think trying out the 21 degree position.
(I know this is getting off the original topic........my appologies to those coming here to read comparisons between the HT2-TL and the HT3)
