Rotted Woofer Foam
Edge Replacement
A common problem
that happens to the most careful of audiophiles is that the foam edge (outer
suspension or ring) of most speakers will dry rot. The technical name for
this part is an annulus. About
ninety percent of all home stereo speakers use this material as a suspension.
New “high tech” woofers with polypropylene cones and butyl rubber edges will
not suffer these problems but could develop others. This dry rot problem is caused by age and certain other environmental factors
and has nothing to do with your kids “jamming” too loud or the movers that
you think might have broken them in transit. Speakers that have never been used and have been in storage for 20 years
will develop this same problem. This is the most
common problem that I see with stereo woofers and can be
remedied by replacing the foam edge. Even those of you just browsing
this page should take the “pinch test” if your speakers are older than eight
years. Place your thumb and forefinger on the foam bump of your speaker and
give it a small tug. If it is intact, you are safe but please repeat this
test every six months. If the foam comes off in your hand, please drop us a
line for repairs. Both of your
speakers were manufactured at roughly the same time
and will rot at the same rate. Many people call me and initially tell me that
only one speaker has a problem. They think I'm The Amazing Kreskin when I
tell them about their other woofer. Customers eventually bring the other
woofer in for repair, as the difference is so obvious. As an incentive, I
offer a reduced rate if both speakers are brought in for repair at the same
time. You wouldn't believe how much time this saves. Contact Us Phone: 502-969-0140 The best time to reach us is
