Prof - I want to thank you personally for cheering the 02s awhile back. Your enthusiasm caused me to get a few pairs which are now my primary workhorses for comparing solutions and making sense of upgrade package choices.

The stock 02 is surprisingly good. Plus, it is readily upgradeable via braced cabinets, XO components, etc. and the application of the laminar-launch baffles and work in process of the new port fluid-flow technologies. I recommend all of you find some. We'll have both DIY and home-based upgrade packages sometime this year. I have some as Christmas presents with stock drivers and crossovers, with modified baffles and grilles. What a treat to give, And BTW, they shine compared against some current market darlings.

About your hunch concerning dry and moist air and sizzle sound ,
I have noticed that everything sounds smoother and sweeter when it's raining or high humidity, so you might be on to something .
I always suspected it had something to do with the transmission 
of electricity .

Tmsrdg - I don't have 3.7s, but there is some baffle flat. My 1.6s benefited from laminar launch baffle treatment.

" Cascadesphil - my working hypothesis is that dry air and moist air couple and resolve the various forces differently - not a theory, but a hunch developed over the past year of experimentation."

Tom - thanks.  I sort of figured it could be something like that.  After one session, where I had some issues, I actually grabbed my allen wrench to make sure the drivers were tight and they were.  For a bit it drove me a little crazy (and some would say that's not a far drive) and I went back to the video on how the 3.7s were made and was thinking about looking inside.  Then when I played the same stuff where I didn't notice a problem.

Back in early March of 2020, I had my AC units tuned up (as I usually do annually and I have two zones, one for a large bonus room upstairs and I go upstairs about once or so a week to move dust around and flush the toilet).  Bacteria gets attached to the area around the coils and they get cleaned with either wipes or Lysol.  I decided to put in the Patriot UV light (https://www.patriotiaq.com/#!/Patriot_UV) on the main zone (and my bedroom and the living area I use is on the main zone) at the time of the tune up.

Since then, I began to notice (don't know if it is coincidence) a couple of things.  I've been sleeping a drop better.  Also, I began to notice (at least a bit more) those anomalies with the 3.7s.  I probably noticed them before that but to me it seemed less that I chalked it up to perhaps my ears were dirty (I go to the ENT on average about every 10 months as my ear canals build up wax) at the time.

So put a felt cloth on the flat space above the tweeter on the 3.6’s?
