Laser measurement for speaker position

This is not a practical, useful, or meaningful approach unless you are also planning, intending, and expecting to also align your head and ears using the same tools, technique, and method!

@ clearthink

Works great for alignment to listening spot!

Made a big improvement in imaging with my Magnepan 3.6!

How do you align your speakers?

Do you just throw them on the floor?

  Maybe clearthink isnt thinking so clear. I have used a similar method before ,a more primitive approach with a lazer light to get toe-in set  at the seating position and a good old fashion tape measure ....but i understand your approach.

The laser level is a practical, useful, and time-saving approach especially if you are also planning, intending, and expecting to have really good imaging, soundstaging, and palpability.

Sorry, don't know why that happened. Something got into me there.

Even a very slightly different distance to each speaker diminishes imaging.

In addition to measuring, calibrating, and... sorry, SORRY! a level is great for making sure the speakers are, uh, level. Or, if you prefer, at the same angle. 

In other words don't just measure the line of sight distance, and toe, but also the tilt front to back and side to side. It makes a difference, and floors cannot be trusted to be level!

yes
and buy Jim Smiths excellent book on getting better sound

Yes, I also give Jim Smith’s book a must have!

millercarbon.....yes ....Vandersteen clued me in many years ago. you're absolutely right.

@clearthink
I have to disagree. Let us know your method.

@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. 

Fascinating story about the party.  So to be clear, you're having a social gathering at your house and the topic just naturally turns to your listening acuity and the precision of your loudspeaker/listening chair setup?  Okay.  And at this gathering some wild and crazy guy decides to play a joke by moving your chair and seeing if you notice?  (I can only imagine that copious amounts of alcohol were invovled).  Though the chair move was not visible to the human eye, you still were able to immediately hear the deleterious sonic effects.  Was the lady as impressed as we are?

Great find. I use a laser measure for the same purpose and I agree it's really useful, but it was more expensive than this one.

To those who are objecting that a fraction of an inch doesn't matter, that's probably true, but getting things reasonably close does and it's a lot easier to do that with a laser measure than with a tape.
