There are some great calculations and theories for optimum placement available to us, but none of them address the variables that are unique to your room, so they aren't an absolute or one size fits all solution. Use those theories and calculations as a starting point, but don't be afraid to experiment and find what's optimal for your room. If it pleases you and works in your room, it not wrong. 😉
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.

The key is you use something consistently, that is all. I always use the front plane and tweeter for toe in. As you know, all the recommendations are only starting places. So, it only maters you use something consistently. As an example, the recommended starting toe in for my speakers is to cross the beams 18” behind my head in the listening position. In my room, they sound best…. by a large margin with zero toe in. None. 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. |
Thanks to all for responding. @bigtwin , I did read your response in the other "room size" thread. Like the OP of that one, I am working with a small space. When you posted this formula, I did not, at that time, work with any of your measurements. I just went back to take a look to see how it would apply to me, and the center of my midrange driver (these are monitors on stands) is 33" You stated that floor to center is usually the shortest (therefore 'A') but it doesn't have to be, correct? |
@immatthewj Correct. The shorest distance can be any of the three. I think normally there is a Bass driver on the bottom and therefore that would most often be the shortest of the three. Use the formula and the speakers can be in a variety of positions. In the end, it's how they sound to you. Cheers. |
