kind of an inside joke I posted shortly after I set up my Home Theater
If you haven't heard the words, you don't have enough subbage yet.
Better and more sensitive than a standard SPL (Sound Pressure Monitor)
and somewhat related to WAF.
...my Spousal Pissedoff Measurement goes off every time
my system has exceeded her tolerance levels...
Furniture, glassware and pictures rattling on the upper level (two storey home)
when I'm all the way down in the basement mancave playing with my toys makes her Lose it!
TTFSD !!! gets yelled down
the open stairwell all the way down to the basement mancave, and its LOUD!
I first heard it go off about 8 years ago, shortly after moving into our new home.
Right from day one I was told the main floor was off limits to my AV gear,
but I was free to do what ever I wanted in the unfinished basement.
...well even that changed the first time the TTFSD alarm went off.
you don't have to add it to your list, it's more of a joke
I have a pair of SubMersives. My guess is TURN THAT F+++ SUBWOOFER DOWN. Well, more of an educated hunch based on personal experience.
