I read something about a golden ratio for box dimensions. Anyone know it?
I think it was some random forum but I read that there was a ratio that someone found made the loudest boxes. It was L 2, W 1, H 2.5. That's a complete guess but you know. I'm gonna build a new box outta mdf this time so I figured I might as well built it with this ratio majig. It might be :lies: but I think it was some box building comp guru dude that said it anyway idk. Oh sweet we get polls!!!

Re: I read something about a golden ratio for box dimensions. Anyone know it?
The "Golden Ratio" should be used whenever possible unless space is restricting which is a normal occurrence when dealing with an automobile. This ratio is 1 x .7937 x 1.2599. For subwoofer cabinets, dimensions with this ratio will sound less boomy and have less panel vibration. To figure the dimensions that you need for a particular volume, without trial and error, you must have a calculator with a "cube root" function. Find the cube root for the volume that you want.
For example, the overall volume you want is 2.25 cubic feet, the cube root is 15.72, make this side one (A). Now multiply side A x .7937 to get side B, or 12.48". Now you have side A = 15.72" and side B = 12.48", to get side C multiply 15.72 x 1.2599 and you get side C which is 19.80". The closer that your cabinets are to this "Golden Ratio" the better they will sound.
(^root X 1, X .7937, X 1.2599)
simplified it states that:
side A (width) is equal to 1X the cube root of the desired volume
side B (height) is equal to A X .7937
side C (length) is equal to A X 1.2599

Re: I read something about a golden ratio for box dimensions. Anyone know it?
thanks man i got it from lilrob (i think) and when i calculated it i found out i didn't have close to the space. my max dims are 10 X 40 (or if its 35 or somethin i can get 11-12") X 22 (taller is possible but the top of the seat is 18 and i don't really want it much taller than it and it starts to push on the back window at about 22. its a soft top so the window is flexible plastic but you know.) so yeah. on the next box i build i'll try n get it as close as i can though. im hopin 2 12" arsenals on a saz 1500d.
