This is a a general audio question and perhaps a strange/funny one.
Recently I got some Ozric Tentacles more or less relatively recent CDs
which has at times extremely low and powerful bass sounds. Caught me
off guard in the car as the car's speakers went booming. And then it
happened a few other times. Now, when I play 'regular' CDs that I used
to play before, I notice that I have to lower the bass by one notch,
compared to the usual setting, as it is more powerful than it used to
be. Or is it just some problem with my perception/eras ? Is it
possible at all that driving very low bass sounds at a fairly high
volume for small amounts of time 'flexes' some speaker membrane and
make them play bass sounds better afterwards ?

Yes and you can buy some special speaker Taibo CDs from me. You should
also buy my special speaker Taibo cables.
Serious: What is a notch on a car hifi bass potentiometer?
If speakers should suffer that easy under "audio load" they are not good
speakers, even if the sound should be better now, next time it will be
broken.
Do you hear music much too loud with extra much too loud subwoofers?
Take care not to damage you ears. You can buy new speakers and a new
windshield if the bass damage them, but you can't repair your ears.

Neat ;-)

Not much of a pot anyways. Digital settings -5 to +5. A notch is 1
digital step

They are not good speakers. These are stock-no-option speakers.

Nope, it's still reasonable. Can't go that loud with a cheap system
anyways. The average rock concert would have done the ear job years
ago.
This thread will probably be something out of the twilight zone.

Dunno in what way you're listening to music. seemingly I was mistaken
with my subwoofer theory.

Health label:
At some point the ears are that damaged, that the sound becomes muddy,
while you can't boost the high frequencies anymore. At that point you'll
start to attenuate the bass frequencies.
Hopefully this isn't the case for you.

If they truly sound different, then they've been damaged, and are
likely to continue to be more damaged.
It could be that you're paying more attention to the low end tho.
That's all very Strange[itudes]. ;-)
Cheerio...

right. Never underestimate the subjectivity of your ear/brain
receiver, both the physical and psychological aspect. In the last six to
eight months, due to neighbour complaints, I've been listening to music
and monitoring at much lower levels. Surprisingly, I find my perception
of "loudness" is much more sensitive, and my "internal" dynamic range
is
much increased. Another thing to consider is the environment: did you
change anything inside your car recently, which might have been
absorbing low frequencies? If in doubt/curious, you could always run a
sine sweep through your system and see if something odd comes up.
Finally, make sure you don't have bass boost turned on by mistake! :)
Seriously, though, you'd be amazed at how many listening systems have it
turned on by default. I have a pair of (otherwise decent) little
speakers which insist on toggling bass boost on whwnever switched off
and on again.
Cheers,
S.M.

Just changing the volume will alter one's perception of tone
and frequency content.

There have been improvements over Fletcher-Munson over the years, but
the basic idea hasn't changed.
G'luck....
