I know some will say that only the 'air space' interacting with a given driver matter. The actual shape of the enclosure is of little consequence.
I have always believed that dimensional ratios play into design. (and please don't quote me the inverse square law-- that is really rudimentary)
I came accross an article on Fibonacci numerical sequences which I found fascinating. http://en.wikipedia.org/wiki/Fibonacci_number
In simplest terms it is a mathematical sequence that appears in nature, art, music, studio design, architecture and dare I say "snake oil" speaker wire. http://goldennumber.net/acoustics.htm
I know by instinct and past experience the the Fibonacci ratio of 1 : 1.618 is a natural choice for studio design. And apparently the dimensions of a Stradivarius violin.
Does this apply to enclosure design?
