Hey guys,

I'm setting up speakers in a 37 x 18 feet room that is mostly empty. I have many questions, but to start, where should I place my sub? I have a pretty big room to work with so should I move the sub as far away from my speakers as possible? How does 15 feet away from the equalaterial speakers? I heard 15 feet is the length of 75-80 hz which is where my krk 10 sub is at. Is this good advice at all? If I set it to 40hz, would that be 30 feet away?

What's the ideal size of the equilateral triangle? Does it not matter so much as long its its equal distance?

For the subs, I found that's its best to just put the sub about where my head would be, then go around the room finding the spot where the best is clear and loudest, then put the sub there.

Starting rules to go by:

1. place your monitors in an equilateral triangle with your head.
2. Place the sub asymmetrically in the room to prevent standing waves.
3. If your room has a lot of hard surfaces you should consider something to dampen the sound, be it panels, carpet, or professional acoustic tiles.
4. Accept that every listening room will color the sound no matter how hard you try to remove it.

Use reference audio material you know well to help you get accustomed to the environment like a favorite song/mix.

Here are just a few sites to help:

And finally, don't worry about it too much. Unless you're aiming to be a professional mix/master engineer don't obsess the tiniest of differences. Unless you want your hobby/career to becoming an expert at monitor placement and room treatments.

Good luck.

Should you place monitors also assimetrically to room walls?

Also, the best assymetrical placement is golden ratio

I have my computer table including speakers placed centered on the long side wall of my room now. It makes such a difference that it isn't funny anymore, the sound is alomst 3D with lots of room to spread out everywhere. Before i had it in a small niche, which was horrible due to the bass resonance, and overall muffling of the sound. Then i tried it on the long side, close to a corner. Which was even more horrible, because i again had bass resonances on one listening position and very thin sound with almost no bass in another position. I'm very happy with the way i have it now, centered on the long side wall. And about 20 centimeters away from the wall.

I also read that this is the best way of positioning the speakers:

1. place your monitors in an equilateral triangle with your head.

It's possible to get standing waves at almost any frequency. However it tends to be most noticeable at lower frequencies because the period of the wave is so much larger than higher frequency content. Lower frequency content doesn't refract as much, it's why you can hear your neighbor's bass but not their treble. Room treatments to dampen refraction at higher frequencies are more than enough to remove standing waves from higher frequency content. Subs are less forgiving though.

As for triangles, the most important thing is your head and the near fields are equidistant from each other. The near-field monitors don't have to be the exact same distance. An isosceles triangle works decently too. Just don't place those monitors too far away: they're called near-field for a reason.

I don't know anything about golden ratio monitor placements to make a comment on it.

Divide your room up with imaginary lines of odd division numbers. So for eg, draw 3,5,7 etc lines across and down your room, and place your monitors and listening position on the points where the imaginary lines cross.

Your sub placement isn't written in stone. It shouldn't be placed in any centre division of the room, but it should be within a reasonable range of your monitor distance.

Have a look at the Genelec monitor set up manuals..

[edit] Because I'm new here my links for the manuals won't show up. Google "Genelec Room acoustic interaction pdf" for more info.
