...or is it pointless because treatment will null out the fairly nice modal distribution anyway?
The dimensions are 16.25' x 26.25' x 10' <l,w,h>. It's not exactly Fi, but rounded up to the nearest quarter inch. I put this into bob gold's room mode calculator and it gives a good looking result. http://bobgolds.com/Mode/RoomModes.htm Anyone ever seen a similar studio design before?
A Fi rectangular room design, naturally good?

Maybe I'm just ignorant, but what do you mean by "Fi"?"A Fi rectangular room..." ... "It's not exactly Fi, ..."
To be honest, that's NOT a very good looking result! I've seen worse, sure, but that isn't a particularly good one... And what kind of room are we talking about here? Maybe if you were to read the stickies on the first page of this forum, and re-post, folks would be able to help more... - Stuart -I put this into bob gold's room mode calculator and it gives a good looking result
Camsr,
Please read the forum RULES (stickies) that can be found at this link:
viewforum.php?f=17
Please correct your initial post to conform with these rules and guidelines. Many here will not only NOT help while waiting in respect for owners and other better qualified persons to proceed, but will simply ignore these type of posts completely.
You may want to immediately ask "what is it that I have missed". Most often it is as simple as including your geographical location in your profile.
Trust me in that the more you know the better others can help you and that the answer to that question is in the forum rules linked page.
Until then, good luck,
Brien
P.S. Pi?
excuse me, Phi is the term. you know, golden ratio, 1.618 ... i took a ten foot ceiling which is common and multiplied by phi and then multiplyed that result by phi again to get a hypothetical room dimension. just wondering if it has any merit in a simple rectangle design. why do the resonances look bad? is it because of close low frequencies resonances might cause beating?
The problems I see with modal issues for that ratio and those dimensions is the uneven spread at the very low end. You have several major modes (forst order axial modes) that are located all by themselves, totally separate from their nearest neighbors. Such as 21.5 Hz, then nothing until 34.8, then nothing until 40.9 but with 43.0 right next to it, then nothing until 55.3 but with 56.5 right next door, etc. It's not a smooth distribution, which is what you would get from using a Sepmeyer or Louden ratio. That's also a pretty long room: nearly 8m. What do you intend to use the room for? CR? LR? Something else? That all makes a big difference. - Stuart -why do the resonances look bad? is it because of close low frequencies resonances might cause beating?
i was thinking a control room or a tracking room. might have a space available but most likely no. glad to hear why this isnt an optimum ratio anyway.
