"It’s NOT something "you do you don’t". I suspect your simplistic understanding of the physics of music is what leads you to think rotating knobs and blocks of wood in a box constitutes tuning. The only means known to effectively tune an instrument or enclosure are to manipulate it’s mass, size, or tension, none of which rotating blocks of wood in a box actually do."
As with your other statements of questioning I’ve shown the forum here that Tuning is exactly what we do and have seen other users come up to verify. The great thing is when those folks here ask questions to attempt to disprove it ends up proving and ultimately leads listeners to the "tune", which of course is my goal.

If you look at the Tuning Bar Technology I use in speaker designing you will see there is a Tuning Bar that runs from one side of the cabinet to the other. I make several types of Tuning Bars at several pitches and tonal range. Kosst above mentions "tension" which is a huge part of my designing. From the outside of the speaker you can see the Tuning Bolts on either sides of the cabinet and in different places on different designs. On the inside are female threaded stationary bars. Going from one side to the other it goes like this. Tuning Bolt, washer (or other Tuning voicer), outside cabinet wall, soft pulp (or other material), inside cabinet wall. Then the bar runs to the other side doing the reverse. Bar, innerwall, pulp, outerwall washer and bolt head. Folks can see the construction on TuneLand with pictures and diagrams and more explanation of the tone and timbre controlling, but to answer Kosst’s comments yes as the Tuning Bolts are threaded into the internal Tuning Bar. One can apply more or less tension to adjust the tone of the cabinet. These speakers literally are acoustical instruments.
Nothing spins on the inside as kosst has alluded, but that's ok I understand this is a new technology for him and he is exploring this like anyone else. I also do want you to know kosst, I appreciate Q&As that have relevance to topics and more than happy to have you come to TuneLand to discuss things on a deeper level. The Agon forum is not really a technical forum, but that shouldn't stop people from visiting both sites to see how deep someone may want to go. It's all good and even though some start off as doubting toms at first it's fun when the commonalities start to happen.
