Perfect Speaker Placement - Put next to the back wall as much as possible.

Hello,

I happen to find an good article about the ideal speaker placement. 
(Easiest version without numbers & formulas that I can’t honestly understand :D)

I’d like to share. 

Personally I find two things interesting.

1) Only use 40% of the room area (38% rule)

2) Put the speaker as close as possible to the back-wall (next to bass trap)

Of course, minor adjustment would be required depending on speakers.
Still, I think this is helpful to figure out the very first step.

Happy listening.

p.s. what should I do with half of the room left... :?

The usage is different, but acoustics does not magically change, and goals acoustically need to be similar.
Control room acoustics are nothing like home.

Walls, floors, trapping, etc. vary massively from studio to studio.

Large control rooms may have 15 to 30 x 3 to 5 feet of glass, often with an angle or two. Ceilings may be 12 feet or higher. There are often racks of equipment with metal face plates behind and/or to the side of the engineers position [EP]. There is a large flat, metal sheet extending 3 to 6 feet either side of the EP. There is a flat meter bridge extending the same distance about 3 feet in front of the EP.

Add in musicians, artists, A&R & record co. execs and it's not at all similar.

Monitors require several multiples the power at 3-4m as at 1m away markedly increasing distortion. Reflections from the back of the console markedly change the tonal balance.

Engineers have dozens of tools to master. Near field monitors are but one.

LMAO at rushfan, I was thinking along the same lines.

Acoustic law dont change but they cannot be applied with blinders...

No small room is the same, and a small room has not the same geometry, the same topology and the same acoustical content than a larger living room...

The acoustic law dont change, for example the ratio 62 to 38 is the Golden section...This is universal from molecules to galaxies and in between corresponding to the optimal distribution of branches all along a tree trunk...But even this ratio cannot be blindly put in action without taking into account anything else...(in my square small room this ratio work)

But a Greek remarkable open amphitheater acoustic is not a closed church acoustic, same laws applied and some other laws linked to the existence of walls and ceilings, same laws but with new one and with great variations and modifications and adaptations..

In fact except some very universal laws about ratio or some reflective principle and absorbing pattern and materials functions and diffusion law in relation with geometrical patterns etc, no room ask for exactly the same treatment and controls...

Any acoustician use his ears not only an equation...Otherwise for example: how to adapt some surface or correcting some diffusive 3-d patterns to the disparate acoustical properties of the different materials in use to construct some room and building and how about the diffrent acoustic properties of the materials and fabric of the furniture?

Geometry, topology and acoustical content of materials in the room are NEVER the same for ANY room compare to others...

All object in a room impact the perception of sound.... Even small one....And dont laugh some may hear that if not you.... Anyway acoustic said so, not me....And i verified some of that in the last 2 years...

In the same way they are general rules for each kind of speakers, but none of them can be used in exactly the same way, locations, distance, if the geometry, the topology(how many windows and doors) and the acoustical content is different for each room where they will put into work...

In acoustic no one can economize or dispense with working ears....

"...Your Maggies and Martin Logan’s may not work as noted, that article was not targeting this type of speaker. However your Triangles, with the proper acoustic treatment would. Just because a speakers name is Triangle does not change the physics of acoustics..."

The answer is; No they wouldn’t. None of my Triangle loudspeakers worked placed near the front wall even with acoustic treatments. It would have been nice if they did because they ended well out into the room. You may not be aware that some Triangle loudspeakers have rear firing drivers so a blanket statement that all Triangle loudspeakers would work on the wall (near the wall) may mislead some people.
Triangle says; " a position far from the back wall reproduces a wide and deep sound image." ...and indeed it does.

The article was not about professional control rooms. Did you read the article? It was talking about setting up a mixing studio. 



I can only expect that most people who are posting here didn't take the time to read the articles in any depth and / or are commenting without understanding the articles.



They are practically how to articles on either speaker placement close to a wall and also far from a wall and whether near field, small speaker or large speaker does not matter. The methodologies and same decision making process must still be applied for optimum results.
