Once my wife had me put the furniture where she wanted it, I staked out my speaker territory and it is in a reasonably good position. Running a sample of white noise and recording with a flat measurement omni mic into my laptop and looking at it in a frequency plot, it was surprisingly better than I had hoped for.

Speakers are symmetrical as measured with a tape measure but I haven't moved them in inch increments to determine the absolute perfect position. Life is just too short for that and there are far bigger compromises made in my (and every) setup.

Use of the RPG Room Optimizer software to set up speakers within a quarter inch made a real difference in my small room.

Maybe not "Nano-tad," but within 5mm.

I used a tape measure to set up the speakers.

Ah, to live in a perfect world. My listening room is far too small. My wife has her own ideas as to how a room should look. Need I say more?

I have a small listening space and near-field listening works best for me at the moment. Using Spendor S20s, I set them up in such a way that they are 6' apart, 1.5' from the rear wall, 3' from the side walls, and I am listening 8' from them. I situate the S20s to face me directly such that I cannot see the enclosures' sides. At such configuration, I am able to obtain the most decent sound from my system.

And a 10kHz wavelength is ... how long?

it is very difficult to obtain a proper alignment because the room itself is the most important thing to arrange and this is impossible!

I have to fight with my "symmetric" side so I have them set as well as possible but maintaining the symmetrics. Thankfully, they image so well that I really don't think it is an issue.

You gotta be kidding. I sort of set them up, and sometimes I may play around so I can just see the inside of the cabinet. But seriously, one darn bourbon and I'm happy. Besides, when I go to the show we drink bubbly before the first half and during the intermission so this way I have my own "absolute sound." Really, some people are too neurotic.

Laser-aligned. It seems that imaging is extremely dependpent on speaker alignment.

Speaker alignment is everything. Without it, you can throw your equipment away.

Two-channel stereo can project a soundstage larger, deeper, and taller than any surround sound system, but only if precisely aligned. Move one speaker even 1/16 of an inch and the whole image collapses. I always have tape measure ready at hand if this happens.

They are perfectly aligned with where my wife will allow me to put them.

After much trial and error, I have speakers and seating arranged for the best that can be hoped for for a given listening environment.

There was no choice here for

Furniture and TV location have prvented me from locating them in my "family room." My wife is unhappy with the location and when I move them too close to my CRT Loewe TV the picture is effected.

I spent a lot of time working on aligning my demo ProAc 3.5s. I have to admit I was at a bit of a loss until my then salesman; John Devore paid me a house call to upgrade my turntable. John immediately analyzed my speaker set up and advised moving the speakers out from the back wall and tipped inward. I ended up pulling the 3.5s 4' out from behind and 16" in from the sidewall shelving, leaving 5' in-between the pair. Then after a lot of listening, I ended up pointing the left speaker at my right ear and the right speaker at my left ear. Voila, finally a seamless sound stage and pin point imaging. My sweet spot is 6.6' from the centerline between the front of the speakers.

Triangle sweet spot.

My speakers are way out of whack, but in a fairly precise way. The problem I have with "nano-tad accuracy" is that my room dimensions and acoustical properties have no such precison. My room acoustics are very asymmetrical, so my speakers must be as well. One speaker is toed-in quite a bit more than the other. It looks very weird but it's the best solution I've been able to find for tailoring my speakers to my room.

I have them positioned down to 1/16". I use ESLs and positioning is extremely important. After getting the positioning correct I move my chair forward and backwards in 1" increments as a tone control.

My B&W 804Ns are spiked to the floor thru the carpeting, so I made sure they were placed correctly. But my chair probably gets nudged aroud a bit, since it isn't spiked.

Move them around till they sound the best and then make sure they are equa-distant from the listener and the listener is centered. No rocket science here.

Actually got out a tape measure.

I'm a prisoner of the room dimensions and layout! We're shopping for a house now, so my speaker placement practices may bump up a notch or too once I have more control.

When I pull my Snell XA75s out into the room to try for better speaker/room interface, I will use a tape to make sure the speakers are the same distance from the wall and to the chair. I use to have a great listening room in that it was 1.6 x the height x 1.6 x the width x 1.6 the length. I loved that room. I had a pair of Polk SDA speakers that I had placed a sticker on the back of each with where in the room to place them, it was magic. Now my ex-wife calls my great listening room her "living room." So goes life.

Almost more important than which speaker you place.

I find that the closer you place speakers to room boundaries, the more difference even a few inches makes, so I genereally will move speakers three inches at a time, then measure and move, measure and move and so on, until I find the position that gives the most flat and extended response, combined with good imaging precision and three-dimensionality.
