Anotherspeaker placement question (distance measurements)


A couple of threads on this topic (one in this forum & another in, of all places, amps & preamps) have got me tweaking placement in my own small listening room.

I am getting that the recommendations for distance from speaker to rear wall are from the FRONT of the speaker to the rear wall, is that correct?

And as far as the recommendations to the side wall, is this from the outboard edge of the cabinet itself, OR from the center of the driver(s)?

I am assuming that listening position distance to the speaker is measured from tweeter to ear, NOT the shortest difference to the plane of speaker to speaker to the ear?

And yes, I do realize that it is not the recommended measurements that one should be concerned about, but how one’s speakers actually perform in one’s environment regardless of these measurements, but for the purposes of experimenting with some of the advice given in the two threads I have alluded to, proper interpretation will be helpful.

The distance that most concerns me, the one that I have the least flexibility to adjust per recommendations, is speaker-to-side-wall-distance. Meaning my speakers are too close to side boundaries. But my lateral sound stage is the best part of my system’s sound stage . . . it presents the illusion of being wider than the boundaries. Is lateral sound stage more a product of speaker-to-side-wall-distance? And if not, does speaker-to-side-wall distance have an effect on a specific aspect of the sound stage?

Thank you in advance for any & all input.

OP,

Thank you for your kind words.

I can’t tell you how much better my system sounds with the careful tweaking I have done (something a system at any level can benefit from). The room tweaks… getting the equipment racks from in between the speakers. Deadening the wall behind, speaker placement… etc. have improved the sound quality.

You noticed the room… well that was luck. The best room I have ever heard. My audio guy as well… and he has been installing $100K+ systems for over 20 years… many in dedicated, purpose built rooms. As I said luck there.

BTW, in a previous house, with ribbon speakers using a 1’ wide by 4’ strip of thick wool carpeting made a huge difference in imaging. While a much more modest system, I would have put it up against much more expensive systems. It is not all about cost… tremendous advantage can be gained by effort. 

But, your system can be every bit as rewarding to you. I have had many systems, and listened to dozens “better than mine”. They helped me shape the direction I took in constructing mine. Listening to great systems is a great way to learn. Surprisingly, often jealousy does not ensue.

My dogs enjoy music and are why my audio seat is a love seat… one place for me, and one for the dogs. I also love it when they take up an attractive pose in front of the system.

@ghdprentice , oh, don’t get me wrong, it wouldn’t be jealousy (well, maybe a little bit of envy, if I was totally honest), but I think it would be hard to listen to mine after hearing a system on that level.

I remember back in ’94 or so when I started down this destructive path, my wife & I went to a brick & mortar "hi-fi" store because at the time I was wanting to move up to a Carver CDP that featured a 6DJ8 in the DAC. (I certainly "progressed" since those innocent days.) Anyway, after I listened to some stuff in one of their listening rooms & had met a couple of salesmen, one young guy (& I was young back then also, but he was younger) was telling me about his Silver 9s (or Silver 7s, I cannot remember which) and also about Winston, another salesman I had met, who had to get rid of all his stuff and wouldn’t replace it with "affordable" because his previous gear had ruined for something less. I can maybe see that.

Anyway, there is a lot wrong in my room, but one thing I’ve got right is no gear between the speakers or on the back wall.

However, as far as my dogs go, I give them run of most of the house, but I don’t trust them (one in particular) a whole lot, & therefore, they don’t go in The Room.

@ghdprentice  Now sure I understand your insistance for no gear between speakers.  Explain please?

@bigtwin  , I cannot and will not try to speak for gdhprentice, and I hope he does offer his explanation so I can learn if what I think is correct  Anyway,  I remember back in the 90's when I had a prescription to Stereophile, I had read in one of their articles that keeping the area between & behind the speakers clean made for better  imaging (I assume center imaging) & I thought I remember reading that it could have an effect on the soundstage.

But with all that typed, a lot of what I thought I remembered learning from Stereophile gets routinely debunked on the forums.  Meaning maybe I misinterpreted what I was reading or maybe there is more than one way to skin a cat & the way they wrote about it in Stereophile was the wrong method.

Anyway, hopefully @ghdprentice  will weigh in on that.
