Anotherspeaker placement question (distance measurements)

"I ain’t ever satisfied," Steve Earle wrote a song by that title.

@bigtwin , with the adjustable dimensions from the formula that I used to achieve 32.75 (or quite close) I did some listening. These dimensions put my speakers closer to the rear wall and further from the side boundaries,and since being further from the side boundaries moved them closer together, I had to move my listening position in significantly which, needless to say, increased the space between me and the book shelf covering the back wall.

"Comparisons are odious." I don’t know about that, but I hate doing them. It seems like when I try, I am never positive about what I heard the last time that I am attempting to compare to.

Anyway, what I feel that I might have noted (how’s that for being definitive?) is that the lateral sound stage is not as dramatic now; it still extends beyond the the speakers, but it doesn’t seem like (maybe) it is as far beyond the speakers. I always did & still do have great center imaging. However, I do think that (maybe) I am hearing more of a fullness from the forward plane of my soundstage to the back of my sound stage. However, the imaging within fore to aft is not as precise & revealing as from left to right & it never was. I don’t feel that height of the sound stage was affected, or if so, not by much.

One thing for sure, I previously made some comments about needing to turn off the lights & close my eyes or it was like sticking a pin in the balloon of my soundstage, and now with the speakers closer together & me even closer to them it is twice as true.

I am thinking that it would be the speaker placement from the side boundaries that would affect the lateral soundstage the most?

Next time I evaluate I’ll tweak only that dimension a bit and see what happens.. Like maybe an inch. I am also thinking I’ll hang some wool blankets on the side boundaries and if that is an improvement I will seriously start considering some type of room treatment beyond that. I have been playing the same three SACDs every time I do this, and I’d kind of like to listen to something else, but I am afraid that would really screw up my ability to compare.

Let’s address the elephant in the room — what are your room dimensions and on what wall are your speakers situated?  Not sure why this critical info has to be a national secret.  Sheesh. 

So, it is really true. Formula are simply a starting point. For me, I did my movements over a year. I plunked them in the prescribed place. And listened for a couple months (they are really awesome speakers). I realized they were capable of disappearing, but were not and the soundstage was restricted. So, I toed them out some. Listened for a couple weeks. No question… better. Moved again. Better. Some folks move, listen, move, listen… in a day. I find that confusing. I prefer listening to the music and wholisticly appraising the change.

Thank you, @ghdprentice  , I am keeping this in mind as I work on this.  You are more patient than I am.  I am often lazy, but less often patient.  I am using the formula that bigtwin provided as a place to start from this time around.  In the past it was always how far do I think I can get away (get away from a sonic perspective, not the perspective as 'am I allowed to') pull them out & spread them a part.  This is about as scientific as I have ever got with this aspect of the hobby.

Probably because everyone will tell me to give up & quit bother trying?

Okay, from the bare wall I am using to place the speakers along to the integrated book cases(s) that cover the back wall is 8'4.  To the left of that is a even boundary, that I have been referring to as a wall for the purposes of measuring, is a gun safe and a file cabinet, they are about 5' high, and they double as an equipment stand for my amp & CDP; above them & attached to the real wall are two shelves which hold my preamp and the power supply for the preamp and several pieces of gear that are being unused at the present--therefore there is no gear behind or between my speakers.  From that boundary to the righthand boundary is about 8'.  This boundary is a file cabinet and book cases filled with books and CDs which extend up to a shelf near the ceiling also filled with books.

Using the formula @bigtwin  provided I started with slightly less than 27" from 'front baffle' to wall and 22.25" from center of tweeter to side boundary.  These are B&W 805s.  I tweaked them to 27" & 22".  Without getting up & measuring, I believe center of tweeter to center of tweeter is 47" and to achieve a ear equilateral triangle, I have about 21" behind my ears to the book case laden rear wall.

As I have previously typed, in the past I had height and a lateral sound stage that extended beyond it's boundaries.  There was/is a less clearly defined sound stage from front plane to rear wall, but none the less, a sound stage.  I lived with what I had before, trying occasional placement tweaks, but it was a couple of recent threads here & in amps/preamps that got me going on this recent endeavor to see if I could achieve more in this small flawed space.  However, with the lights off & my eyes closed, my speakers to disappear. 

@ghdprentice  , I went to your page & looked---awesome room and system!  Way, way, way out of my league.   I hope you still have the dog?  I did a quick search on your speakers and I may be being materialistic, but I believe that to a large extent you get what you pay for.  I believe you when you say that they are wonderful speakers.

It would probably be a bad idea for me to hear a system like that.  Most nights I am not hearing my room or my speakers--I am hearing the music & I think things sound fantastic, but fantastic is a relative term and hearing gear of that caliber would probably be the ruination of my own experience.

In the mean time I'll keep working with what I have and after looking at yours I think I am going to experiment with throw rugs and blankets and if I get some sort of positive results I'll look into room treatments on a higher level.

Rock on!
