1. How can I tell whether a cone is original or already a reconed cone?
My cone (the cone to repair) is all paper.
2. How can I successfully remove the old cone, spider gasket and
surround ? Sure one can tear it out using brute force but maybe
there are good reasons to do it with keeping most of the parts intact.
E.g. to obtain the exact distances between coil, cone and spider in the
repair process.
3. How do I aftertreat the gasket?
4. What glue do I use to attach the coil to the cone?
5. What glue for the aluminum dome (dust cap)? I see that there is
some black (epoxy) glue being used often? Noone could glue
these dust cap as perfect as JBL themselves. All recones I was able to
unveil as such showed a more or less smeared or jittery glue traces
while original domes look near perfectly glued.
6. What glue for covering the voice coil wires?
7. What glue for the spider to the cone? Spider to the basket?
8. I see some "wet" covering on reconed JBLs on the surround. The cone
and textile surround I received is "dry" but I understand it is a good idea
to soak it with some permanently elastic liquid/glue (term?)
9. What do I assemble/glue outside the speaker? Do I leave off the dust
cap or do I assemble everything outside the speaker?
10. Is it recommended to build a holder or template or some kind of fixture
construction?
11. In which order does one proceed? My idea is to start with the cone/voice
coil connection.
But I think it would be a good idea to build a fixture for
a) making the voice coil a perfect circle shape
b) aligning it exactly in relation to the cone.
12. How long the tinsel wires? In what shape hang them? Under what angle
solder them into the lugs?
13. Centering process of the voice coil?
Questions over questions. I will stop here for now and I'm expecting your gracious answers.
