Speaker voice coils are usually wrapped around something substantial such
as a cylinder of cardboard. The windings comprising the voice coil in
the PC110 speaker consist of nothing but the wire itself held together
by glue. At high volumes the glue comes apart and the wire tears loose
from the cone. I tried a repair job but aligning the coil with the
circular slot is too tricky to be practical.
>Any ever replaced their PC110 speaker?
Yes, twice. Small speakers are hard to find, but I found a sufficiently
small on in the Digikey catalog.
