An ANSWER....of sorts......

....the drone you hear, but can’t se

I smell a DOD contract in there....😏🤦‍♂️

Serendipity coupled to acoustics basic can make miracles!

I just walked as every morning, i stumble on an empty 6 foot cylinder made of hard -plastic abandonned in a field...

I entered in my dedicated acoustic corner ( near listening field with my modified small speakers).

I fix the tube with the proper wood closure at the end and put the open part vertically between my two speakers...

I need only one trial tuning ...

Very audible improvement at the right frequencies range resulting in a better listener envelopment and a better timbre ...Thanks Saint Helmholtz...

Pay attention walking and pray the right god....

'Sample & Hold' started near here...and done well....

@immatthewj ....*knowing S*  I was dazed 'n confused for awhile...then opted to 'life-style' the situ, get comfy, and tarry on....

...besides, we're cute when slack-jawed and blank.....

("Legs" loud, if you will...
I can find rhythm in a jackhammer....)

@tony1954 ...."Blank" isn't necessarily a Bad Thing, really....and 'streamed unconsciousness' can prove to be very liberating...

...if liberation, with or without libations or infused confusions attending....;)

*sigh*

Intro invisibility to one's peers, and they keep looking on the other side....🤦‍♂️🙄🤷‍♂️🤨
