But ,...... there is a catch with wilson speakers .
From the pics i have seen and read from various wilson installs one can change the mid and tweeter output via out board resistors at the back of the speakers .
So IF the transparent cable works indeed in the audible band , one can change the resistors and get a straight FR again , i advise only to do this with a wilson expert preferably with loudspeaker measurement gear
Your IF is deeply wrong. Transparent Audio cables do not act in the audio band. I said it several times in this forum, however it is one of the favorite speculative items of this board.
The networks are tuned well outside the audio band. They do not change the frequency response of systems like resistors in the crossovers.
