All 7 rooms in my house`s A/V system`s speaker`s grill`s are always on.
`Cause you never know, even though my house is a controlled environment with no wife, children, dog, cat.
or undisciplined visiting friend`s children running wild.
My speakers have their clothes on, and will always be that way, except to service them, especially since I chose to listen to music and not stare at my raw speakers component`s watching the lower frequency driver`s cone movement, since the HQ room`s speakers sound stage permits the sound field to recede past the apparent location of the speakers, as I set them to do.
I don`t care to watch meters, or speaker cone movements whilst listening to music.
Strange, I guess, but to each their own.
