Something Barlow said triggered a dormant brain cell, & I remembered
something from a long ago eno interview about him having set up an array of
different length tubes in front of a speaker cabinet to get different sound
colorations. I may be remembering it wrong, but that's the gist as I
recall.
It has the advantage of giving you more options in tuning your resonances, &
is probably cheap than cello mutilation.
