I know that Ideal is an equilateral triangle. My room is 11 feet wide. And approx 8-9 feet from the center of the screen to the Sweet spot. My TV is 48.5 inches wide. I know that I can put my speakers nest to the TV or a few inches form the sidewalls. Help please. I will be purchasing the M22 I am in the space planning stage and need to design the component rack that will meet the wife’s approval. Thank you all in advance.

Matt

icefrk13,
I had some diagrams from one company that had described a setup for speakers in a room.
It wasn't quite an equilateral triangle, had a bit of simple math to it, but in any event, do not limit yourself to having to keep to such a strict rule.
I've often found that as long as there is some symmetry between your seating position, left and right speakers and equidistance between them if you have a centre channel, that stereo sound will work quite nicely.
If you are interesed in seeing the setup diagram that i mentioned, i will try to dig it out of the archives for your perusal.

So, assuming that your TV is sitting at the center of the 11-feet wall, you have over 3 feet of room on each side of the TV, right? In that case, my first choice for the M22 placement would be right in the middle between the TV and side wall -- NOT right next to the TV or to the side walls -- and perhaps a bit forward of the TV screen. The M22 will sound better when isolated from other surfaces reflecting sound.

[wow... I didn't say anything about front projection here! Or did I? ]

Cheeseroo,
Thanks for the Offer, but you do not have to go diggin through that stuff. And Sushi you are correct that the Tv is in the center of the wall.

Well i might go find it anyway just for fun. I posted it once a long time ago.
I'm interested to see how my own config conforms to this idea of the mathematical setup.

Matt, it's important to have enough separation, and with your seating position that would seem to call for about 8 feet. The distance of the midwoofer cones from the floor and each of the 2 nearest walls should be unequal, but one of the 3 distances can be very short, if necessary.

The distance of the midwoofer cones from the ... wha? Great! Now I'm going to have to get out the tape measure. Yes, honey. I am crazy.

Following are the images of the Fibonacci sequence ("Golden Ratio") speaker setup formulas as taken from an old Angstrom speaker pamphlet, but once published in What Hifi? magazine.

The setup diagrams are suggestions for speaker placement for various room configurations.

An interesting tidbit on Golden Ratios and loudspeakers "one of the most interesting graphic forms of the Golden Ratio is the nautilus shell and the way the shell starts from a central origin and then spirals outward around itself until it reaches the horn or opening of the shell where the cephalopod's head is located...B&W, designed a reference speaker with the nautilus design and called it the Nautilus."

More info on the Golden Ratio setup and reasoning can be found in this Stereophile article , especially the last paragraph.

Peter, I hate to tell you, since you imply that your wife might comment merely about using the tape measure on the speakers, but that's just the half of it. Next, you'll have her take the tape and measure the distances of your ears from the floor and two nearest walls in order to determine your optimum listening position. Then, you'll do likewise for her. I'm confident that because of your dedication you'll remember and always use your proper position, but special precautions may be necessary for your wife. I'd suggest gluing a pair of footprints(bearing her name)to the floor in her spot. Putting her feet in the proper place will generally position her ears correctly, at least initially, but if you notice her slumping or leaning at any time, you'll have to remind her.

Now, some non-audiophiles might suggest that this procedure is rather low on the WAF scale, but surely a strong marriage can survive little things like this!

If a marriage can survive, "I know they seem expensive and aren't one of the dozens I listened to...", it will survive anything!!!

Got a chuckle out of that one....

It's funny because it's true.

As for the measuring...it's still fiancee for now, but she's had to hold the end of the measuring tape to help get all of this stuff set up in the past

Hmm...

In case anybody is interested in how the heck the Fibonacci sequence, the Golden Ratio, and the Nautilus shell are mathematically related to each other, see this page; especially this section.

Those are some great links.
Explains the theory of the shells quite nicely.

So is there truly order in chaos then?
As biological beings, we can still be broken down into math.
How interesting.

Say Chess, does the Golden rule take into account ported cabinets, where the port faces the rear ? Or would this have any bearing on the formula ? As I type this, I would guess, all things being equal, no.. Correct ?

I doubt that ports do anything to the formula.
After all, it is a 'natural' equation that could be used with any directional sound source and the ports are not designed to produce sound.
However, if you had some dipole speakers in the front, then who knows what kind of sound effect might be produced using the Golden Ratio.
I'm sure someone has tried it.
Again, i doubt there would be a huge difference. One way or another you have to put 2 speakers in front of you at some distance away and apart to create a stereo sound field. With or without a 'formula', this can be achieved but i do believe that symmetry is an important key point.
The Golden Ratio is just an interesting starting point and fun to try if you have the room to tinker. I unfortunately do not.

Here is a link to some info on this setup at the Cardas website (linked from that original Stereophile article).

A little off on a tangent here, but what would you guys think about putting the M22s upside down, ie tweeter on the bottom? When I get mine (eventually), they're going to go on top of some bookshelves next to my entertainment center (most likely) which are about 4 feet tall. Therefore, if I put them right side up, the tweeter would be way above my ears.

Ken

Yes, Ken, the M22s can be positioned upside-down, but since the tweeters would still be well above ear-level, you might also want to tilt them downward slightly. Also note that if this puts the midwoofer cones closer to the ceiling than the floor in your room that the distance to the ceiling should be used if you set unequal distances to it and the two nearest walls.

OK, I need you to go over that last line again... I didn't really get it.

Thanks for the info, though!

Ken, it's just a variation on my previous reply to Matt, when I pointed out(and astonished Peter)that it's good practice to set the speakers so that the midwoofer cones are different distances from the floor and the 2 nearest walls(e.g. 1, 3 and 5 feet). Where the speakers are so high that the mids are closer to the ceiling than to the floor, the measurement to the ceiling would be used instead.

Ah, got it. Thanks! (Now I just have to get Axiom to put the badges on upside down!)

Just pull the grill off and turn it over.

Ah, if only the logos were on the grills! (Unless they are and the website's wrong.)

Nope...I'm an idiot.
