The "most foolish" loudspeaker tweak/upgrade ... is

I think it should be possible to run redundant wiring in both directions to obviate internal (or external, like perception) issues. WIBD for short, and I think any audio geek worth their salt should rip the wire out of every component they own and reverse it to insure that the proper directionality is in play. Now where the hell IS my soldering iron? Damn...

Years ago I had a pair of Vandersteen 1Bs that included a small cat trampoline in their design (I think the new ones include this also). I noticed this did have an effect on their tone when the trampoline/sleeping spot was in use by the cat, and due to damage to the speaker cloth by clawing I sent them back to Vandy for new covers and then sold them. Also, I recently ordered new speakers that include Real Good Wire that if nothing else does make me feel better. Not sure what they're gonna sound like but if I don't like them I'll at least know it's not the wire.
