When you look at the hour hand on a clock it
appears to stand still even though it is changing.
Imagine if hours were years, how hard it
would be to see the hands move! Your older speakers are also changing,
but like the clock, it happens so gradually it goes
Did you know the foam ring circling the
speaker cones rot? This loss of compliance is the CAUSE of reduced
fidelity in older speakers.
A simple test to see if your speakers are OK requires removing your speaker grill and
using the eraser end of a pencil (or your finger) and press lightly on
the foam surround. A good speaker will withstand a respectable amount
of pressure. A bad one will allow the pencil (or your finger) to pass
right through it leaving a hole.
If your speakers are beginning to loose this
foam surround, be aware that the condition can damage your amplifier.
We have had great success in restoring speakers with this problem using
a new POLYETHER foam. These foam does not rot 10 years down the road
like yours may be doing. This product exceeds the original factory
performance and provides consistent performance and high fidelity for
the life of the speaker.
