Spica TC-50 Owners out there?

I have owned a lot of very expensive speakers that come and go but,

I've always enjoy listening to my Spica TC-50's. I did some research
on the internet and found out that there is really no known
replacement woofer for the TC-50. I know that sooner or later the
woofer will come to its end(nothing last forever). Knowing this, I
always take precautions and have to pay attention all the time, like
turning on and off my system in the right order to make sure it
doesn't make a popping sound that can blow out the drivers. I also
don't listen at loud levels for the same reason. This takes out some

of the enjoyment listening to my Spicas. My question to fellow TC-50
owners out there -- How often do you listen to your TC-50? How loud? and
have any blown a woofer yet?

BTW. This is for TC-50 only no TC-60. The TC-60 is newer and uses different drivers.
