"jasee"

Actually I was rewinding the voice coil. (I've done this succesfully
before, but not with this tweeter). It seems that the enamelled copper
wire that was used was not standard enamelled copper wire as the total
length of the dual layer coil was about 2.84metres which in 40SWG gives a
dc resistance of about 3.7ohms. However the original which appears to be
the same gauge measures about 7ohms. So that is that, unfortunately, as
far as I can see. :-(



** KEF's data on the T27 says that the voice coil is rated for continuous
operation at 130 C.

It also says that it can withstand 220C for 5 seconds.

Suggests that the enamelled wire is not low temp ( self fluxing) grade.
