Any interest in Physical speaker setup?

SETTING UP YOUR MAIN CHANNEL SPEAKERS.

This setup can be for 2 channel or Theater use. I find combining the 2 makes for a very sadisfying experience.

What's great about this is without spending any money at all, you can make small easy tweaks to position and get a lot of benefits out of your system. I'm willing to bet that if you have your speakers Not setup to the best you can and you do these steps, you may fall in love all over again with whatever speakers you are using.

So if you have bookshelf speakers on stands or floor standers, doesn't matter, the setup is exactly the same. This can apply to On wall or in wall speakers .

So if you know or not, there is a general rule many people and companies have gone buy for decades , it's called the equal triangle setup.
WHAT DOES THAT MEAN?
So you want to measure your distance from where your "KING SEAT" is to the left or right speakers. Let's say it's 11 feet 2 inches to the front of the speaker. Following the Triangle, you would want the speakers to be 11 feet 2 inches apart and the same distance for the other speakers left of right to also be 11 feet 2 inches.

Now with that being said, over the years I have found that NOT to work out for all speakers. Trying to follow a general rules of this nature just doesn't work out. Your best best for this triangle rule would be to first check your owners manual of whatever speakers you use for your main channel speakers.

Now for me and all the different brand speakers I have setup, I usually go against the recommended setup for a given pair of speakers and I take the room into account and the actual listening distance into account. What I do is look at the room I'm working in, measure the front sound stage wall. This is if you have walls on either side, don't sweat if you don't have side walls I'll get to what to do there.

So I measure the front wall and divide it up into 1/4's. I'll take the speakers and place them 1/4 in on both sides , sit at the listening position and play a clip of a song I know extremely well. I learn how the speakers I'm working with how they sound, how they project and how they like living where I put them. This works some of the time as they could live exactly in this position.

The next thing I use is the 3/4 rule. This is one of my rules I discovered that seems to be more universal Than the equal triangle rule. So I will position the speakers apart 3/4 the distance that the listening portion measurement is. So easy math 10 feet seating distance will be 7 feet or so the speakers will be apart. At this point it's a game of inches. You listen to them at this position and see how they sound strage. How do they Image?

Once you figure out the best distance apart we will now talk about my soft curve technic and toe in.
Distance from the front wall . Sometimes we can't get away enough like 3 or 4 feet out into the room. Some of us don't have that kind of space OR our wife's might not want giant ugly speakers in the middle of HER or HIS room. So again don't worry about perfection. If you can achieve that, great I can get you there, if you can't I can help get you as close as possible.

So the soft curve, Imagine in your head a very soft curve line that your speakers live on. This will not work with on wall or in wall speakers unless you build a false wall. We have flat walls that are usually straight and well flat. Skip this if this is you. Think about the failed CURVE TV's. The idea was to WRAP you in a picture that put you more into the movie. The failure here is no one purchased one big enough to actually experience this unless you sat 2-3 feet away from a 75 inch screen.

So with your speaker distance apart, now start pulling them away from the front wall a few inches, a foot or 2 if you can. But start out with just 6 inches , then go 12 then 18 and so on and so forth to you build a soft curve. let me show you my soft curve to give you the idea of that the hell I'm talking about. A video would probably be better BUT I'll get this to work just fine.



So by looking at my family room setup, you can see the 2 tower speakers and their relationship with the center channel. The center channel appears to sit back just a bit more than the left and right speakers do. This is the soft curve.

Now we are not done. with the soft curve in place , we have to decide on toe in to complete our curve. We have to actually curve our speaker position. Laser pointers really help here but you don't have to run out and buy one. But if you have one, great. You want to place the laser on top of your speaker let's say the left and point it at your KING seat Left ear of someone sitting there. This most likely will NOT be the final position but it's a good starting point. You will also do this with the right channel speaker to the Right ear of a person sitting in the KING seat. This brings the Triangle back into play with angles and curves. What I want you to do once you develop the angle of your speakers in this position is to now listen again. Same song and just experience the sound, how you hear it, what it makes you feel like, loosen the belt people and experince this. Feel the notes, bring them into your core and feel how it makes you feel now. Is this IT or maybe just maybe there is more. Which there is I'll fill you in now. We just scratched the surface of setting up main channel speakers.

Now that you know how the speakers perform them pointed "TOE'D" right into your ear holes, we are going to go even further. Now I want you to set something up 2 to 4 feet behind you. As long as it's not a wall, which we can work with that limitation if need be but let's say you have a few feet behind your seating. What I want you to do now is soften the curve. I want you to place a pole a chair with a pillow on it high enough to point a laser from the speaker pointed coming together 2-4 feet behind you now so the beams will pass your head the speakers will be toed out little to achieve this. So Imagine the triangle extending 2 to 4 feet behind you . Lets make is easy, go 2 feet being you. Now your pointing your speakers so they fire past you instead of hitting your ears , they hit to make the triangle point 2 feet behind you.

Once you get this setup done, I want you to sit down and listen again. Did the sound get better? Is the center image still there or did it fall apart? Is the music soundstage bigger? Does it make more space between instruments and sounds so if you wanted to focus on one thing like a symbol or guitar can you? This is where the Art of setup comes in, this is where you really learn how your speakers like to be setup. This helps you really dial them in to perfection to hear what they were built for, why we all go after sonic perfection. I'm telling you it's not always about the better amp, the cables and all that other stuff at this point. This is the point where you "Tune" your system and man does this process really gets you intimate with your system.

So once this is done, you figure out what the best distance behind you makes the best out of your sound, your done now right? WRONG. There is still 1 more step I'm gonna have you take that MOST people have no clue about. Some of you know this and know it's a level of sonic perfection and why your system sound so damn good. Enter the Mantis Lean. This is one thing I do that most audio guys Installers , even manufactures don't practice. It's what separates me from so many other calibrators.

On to the next post.

MANTIS LEAN

This got cut off and I had to re do this.

The mantis lean is now we are going to measure the height of your ears in your kind seat. Have someone measure the distance from your center of your ears to the floor. Now measure the speakers center of tweeter to the floor and make note of these 2 measurements.

They are usually 2 different measurements and we are now going to tilt the speaker back to achieve another level of sonic perfection.

First your going to level the speaker left to right both of them of course. Make sure they are level.
Here is a pic


Now that they are level, start adjusting the tilt backward to un level the speakers front to back, not not a lot. Just enough move the bubble so they are slightly tilted back. This will re aim the tweeter upwards and change again the way they sound usually a lot.

You can beam the to reach your ear height over the distance from the speakers to your ears to dead center, Yes this can be perfection but sometimes they need just a tad more. What you're going to do is get them to ear height , then listen again. Does the center image sound better or did you ruin it? Does the soundstage sound fuller wider and more open? Can you hear things that create the song you are listening like a guitar clearly or did it smear?

What's happening here is your deepening your connection with your speakers. Your learning how the tweeter projects, I could care less about spec's and what they are supposed to do, I care way more about the experience you are having before and after these technics with your music. Play with the height, go until they don't sound quite right and then back off to where it sounds the best. Usually and this is generally speaking, a slight elevation above ear height seems to work the best for just about all speakers. Some might not and when that doesnt' work for you, you back them down until everything comes together and you are at a point where you never heard your speakers sound this good never.

Thanks for taking to write this up!

I would check out Wilson audios zones of neutrality method as it works extremely well for two channel

I learned a lot working with Wilson audio. I had to learn how to adjust the cubes on the Grand Slam or whatever they were called back in the early 2000's when I worked with them daily. I did a lot of the older Watt puppies but they had way less adjustments to work with . The flagship models of then has these cubes with speakers in them you can adjust for the room . It was painful and hard at times not to mention I kinda hated working with them as they were so damn heavy and very hard to move into place.

I much more enjoyed working with Dynaudio evidence Tempations and B&W N801's , yeah they were still heavy as hell but so much easier to setup.

Egglestones were also heavy as hell but they dialed in pretty easy. Martin Logan were tricky at times depending on the room. Most panel style speakers you kinda had to sit in one spot or they didn't perform to their best.
