i own his Chameleon Speakers. The way to look at is best described with common sense----the tighter the disc, expect more taut bass, pinpoint high frequency images---loosen them, expect more body, fuller, but at the expense of less focused soundstage
From what I learned, from a person who spent considerable time becoming familiar with the speakers is to go from a fairly tight tune, do not over-tighten tho-----listen, then eventually loosen them by small fractions and listen----somewhere between Tight---onwards you will get the sound which sounds best to you and within your system.
the prior owner of mine, had even put a removable sticker with incremental lines to make things easier to reference-
I have a few more bolts on my speaker, but have found I like to keep the top ones tighter, (tweeter range)---the middle ones on the tighter side---and the lower ones (bass) the loosest
hope this helps
