NOTES OF CAUTION
• Because
of
the nature
of
Beryllium,
do
not touch the tweeter
domes with your finger
or
any other body part.
•
Do
not
expose the Beryllium tweeters
to
open flame,
to
avoid
the possibility
of
poisoning
by
inhalation.
• We have meticulously chosen certain glues for their adhesive
and more importantly their acoustic properties. Over time
some reddening can occur
to
the glue edge at the dust cap,
depending on your environment.
