Laser measurement for speaker position

@don_c55 ... I have used a laser measurement device similar to that one, and it worked very well for speaker placement. I agree with you completely ... don’t pay attention to the misinformed.

Those of you who enjoy listening to your Music Reproduction System with their heads fully clamped, secured, and confined in a rigid, steel, unflexible device are welcome to perform such extraordinary but unnecessary, useless, and unproductive efforts to achieve precision.

A measuring tape does the job for me, and slight differences in distance have absolutely zero, and I mean zero, effect on the soundstage or anything else as sound waves traveling through air are not absolutely stable...are your headphone speakers exactly the same distance from your ear canals? Nope...that's because those ears are attached to a (likely) human head...again, it's best to ignore those obsessed with false absolutes and silliness, and try to relax and enjoy the music part of the hobby.

I had a friend who talked like this. One time when we were having a party he thought it would be funny to prove just how silly it is with a little practical joke. So when no one was watching he gave the chair a little nudge. Not much. You'd never notice. I sure didn't. 

Not with my eyes, anyway.

But we were playing music for people and the next one, she wanted to hear this MoFi which I know to be recorded at a different level, and so not wanting to blast her out of the chair or be too low volume either, I decided to sit and listen for a second just to check the volume.

Immediately I noticed the balance was off. Then I noticed the center image was diffuse. Then I noticed the whole sound stage was off, with some sounds seeming to come from the speakers, instead of floating independent as they should. I double-checked balance, nope that was fine. Well then either someone bumped the chair, or one or both speakers.

So it took me all of about 10 seconds, if that, to figure out what had happened. And another 30 seconds to fix. At which point I look and see Ron standing in the doorway, and I only wish I had taken a picture so you could see the look on his face.

Because at that moment Ron knew for a certainty that I know what I'm talking about and you are, er I mean he was full of it.

It is not unusual to spend a few hours placing my speakers. And of course the point is that once your speakers are properly placed you can move your head, if necessary, to find the sweet spot.
