That is true in theory, but this user has found possibly different results in real life.

Hi,

two identical ports with length ratio's of 1.4 gives frequency
ratios of ~1.2. e.g. 40Hz and 47Hz, or 47 Hz and 56hz.

The thread indicates if anything the theory to be true,
as the higher tuned port has more effect than the lower.
