Rives, thanks, I've seen your site and tried the simulator, but I can't get my room dimensions keyed in, as the max width on your simulator is 10m and my room is 15m wide.
Newbee....my room is 45'X 28'. The speakers are 12' apart, 7.5' from the front wall and toed in slightly. I have some restrictions on where the speakers can go. They can't go closer than 18" to the front wall, and can come out into the room past 9' due to the proximity of a staircase. The closest possible listening position is at the 12' point, and the 20.5' position represents the farthest distance, being up against the back wall. The seat can go anywhere between the 12 and 20.5'....Though 12 is a little close due to the staircase and WAF.
There is an 'unreal' change in sound pressure as I walk between the 12 and 20'. At the 16-17' point, the spl just drops way down, and the low frequencies almost dissapear, then it just pops right back in there around the 19-20' area. I'm not really familiar with the term suck-out, though I guess that's what I'm experiencing in the 16-17' area.
To give some more information....the points ABC on the chart are actually A=12' B=17' and C=20.5'
I was amazed that the SPL could be significantly higher at 20.5' than at 17'.
As Sean stated, the best sonics would appear to be at the 20.5 position, given the apparent smoother low frequency extension. In practice, the sound is much better at point C (20') than at point B (17'). But at point A(12') the presentation is completely different than that at point C, even though the frequency/spl readings are quite similar.
There are obviously points in between the 3 positions that are possible, but only really at +/- 12" or so from the 12/17/20.5 points.
Anyway, it's been an interesting experiment for me. Right now I have the seat at the 20.5 position. I'm enjoying the
presentation of orchestral music and some big band stuff.
When I play more 'intimate' music like Diana Krall Live in Paris, or the Sting Live CD, I wish I were back at the 12' point for that enveloping soundfield effect!!...maybe I should install tram-tracks or something.
Anyway, when I moved to this bigger place and splurged on new 'bigger' sounding equipment, I never knew there was going to be so much involved. I wish I could afford to pay for the services of a pro installer who could perhaps get me at the 14-15' point by using acoustic treatments.
What do you think Rives?....I'm 12 miles from the Packer Stadium...I could get you tickets to watch some real Football, and you could fix up my room!...seems like a fair trade!
