Hello. I currently have 2 old (about 30 years old), but very nice (made
out
of 2 in. thick wood). However, as many woofers are made today, they have
the cone in the back for air to come out. Well these tanks have something
like that, but in the front. However, isteand of anything plastic,
there's
a piece of fabric covering the hole (almost like a small grill). Over
time
from all the use of the speakers, this cloth has become stretched and
causes
unwanted vibrations/sound in the bass parts especially. Is it safe to
remove this or should i replace the cloth? or should i just replace it
with
another part? would adding more of these holes produce better sound?
Thanks.

Just a guess from the description, but these sound like bass reflex
enclosures,
and probably are tuned. I would NOT add more holes, unless you want to lose
much of the bass. If the fabric is "slapping" on any part of its support on
bass
note. you could glue it down, stretch it tighter, replace it, or just lose
it, depending
on how important its appearance is to you.
FWIW
