Audio Note Speaker Foam Replacement - Manual

Woofer Foam Surround Replacement Procedure for Audio Note™ AN-K, AN-J & AN-E
Speaker Models
Picture 1
It is an undeniable fact that the best sounding material for loudspeaker suspension is compressed
foam, it is evenly compliant across a wide range of movement and affect the sound of the driver far
less than rubber and other less perishable materials, so it is an unavoidable part of a quality
loudspeaker, it only down side is that, depending on environment and climate, it will perish and start
hardening after 8 – 12 years. In the tropics it may lst as little as 6 years, in a temperate climate
probably closer to 15 years, however do not dispair, if your speakers’ foam has developed into dust
help is at hand, and it is neither expensive nor terribly difficult to replace the foam and revitalise the
sound of your speakers’ to as new condition, here is how!
Picture 1 above & picture 2, 3, 4 and 5 below,
The pictures in the sequel shows a basic procedure for how to replace the perished foam surround
on any of Audio Note’s AN-K, AN-J or AN-E loudspeakers and applies broadly also to the Snell Type K,
Type J and Type E models and probably most other speakers where the foam has perished as long as
the replacement foam surround is the correct type and size, the pictures shows a driver that has
been removed from its cabinet, this is not necessary in many cases and it is actually easier to change
the surround with the driver in situ in the cabinet.
Audio Note™ is happy to supply anyone with a foam surround for the purpose of replacing perished
foam surrounds on older speaker models, we do recommend that unless you are confident that you
can perform this task without problem you seek support before damaging the woofer, which will
require a complete replacement of the driver itself.
