Formula for calculating ideal monitor size/placement per room size/shape?

[Bunjji]

Matters how well you treat the room really. If you have all the corners bass trapped and some of the ceiling, the room could probably handle an 8".

Even a small room?

I'm buying a house soon and am deligating the most convenient room as my studio.
At this point I have no idea what size and shape this room will be, so I was wondering if there were rough guidelines as to what size monitor will react best with the rooms dimensions, particularly bass frequencies.
I keep hearing that 8" woofers are too large for a small room, but does that mean those of us with small rooms don't deserve low end? :(

Theres software available for speaker placement. I havent done it in a while so I cant say whats out there now. Google for eigentones + speaker placement

If the rooom is really small, no, but what I am saying is that with better treatment you can use bigger monitors than you normally would.

If you acoustically treat your space you should be fine. My monitors put out a good deal of low end in my 10x10 room and it sounds amazing in here. I would just recommend a lot of bass traps. You could get a lot more helpful responses in the acoustics section of Gearslutz so I would move the thread there, or make another one in there.

There is a room size ratio often called the Golden Ratio, you could start there.

As to monitor size, the idea that the size of the woofer makes a difference in a small room is basic bull. Don't know how that idea get started or why it has legs, but what excites a room is sound pressure level, not the size of the speaker. If you have a problem at a given frequency and SPL, that frequency will be a problem no matter what speaker or instrument creates it.

So, we're going to tell bass players and guitar players that they can't bring their amps in unless they have smaller than 8 inch speakers? Oh, and no drums bigger than 6 inches?

My ATC SCM-25As sound fantastic in my 12x15 foot room, even though the woofers are bigger than 8 inches.

If you have any control over the shape of the room, a rectangle is better.

When it comes to placing monitors and adding room treatment, there is a lot of info on the web. One of the better sites for treatment is the realtraps site, along with ethan winer dot com. Ethan's book is also a comprehensive tome on the subject of audio, if you care to delve into an over 500 page book with an additional couple of hundred pages available on line.

Theres a wavelength/room size relation. But thats more to do with the bass roll off with a particular speaker more than the size of the woofer. Maybe thats how the bull got started

Yeah, woofer size isn't going to matter much, it will be the freqency responce and how well treated the room is. The only time woofer size would matter is if you are sitting so close that the larger woofers push the acoustic centers far enough apart that you hear the tweeter up there and the woofer down there. That probably won't happen until you try using 10" or bigger at arms length and even then you would probably still be fine.

And to give an idea, I have some small speakers I built that use a 4" woofer and are solid down to 45hz! They will really get some room modes going, though the speakers play some nasty tricks to do it that make them very unsuitable for use as monitors. My 7" monitors don't even get that low.

They aren't. They are only 7 inch woofers...

Thinking seven inches is more than eight inches is sort of a guy thing.

And I BUSTED or what??? Sorry guys, in this little room, things just look bigger! (Damn, I hate when I'm extra stupid...) point remains though, woofer size doesn't matter.

[Blunt]

That's ok Bill. It's not the size, but what you do with it.

This post kinda summed it up well.
So I should ignore the size and look at the responses.
So anything from 40hz to 20khz is ok?
