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.
