removing a speaker's connector panel

[William Sommerwerck]

I'm finally getting around to upgrading a pair of Advent speakers (the
original model with green tweeters).

The connector panel -- on which the crossover network is mounted -- is glued
to the inside of the speaker. I could remove and replace the crossover
components in situ, * but that strikes me as asking for trouble. It would make
more sense to completely remove the panel.

The "obvious" way is to repeatedly run a sharp knife (such as a carpet knife)
along the panel's edges, until enough of the adhesive has been broken that the
panel comes loose.

Is this "reasonable", or am I missing something?

Thanks in advance.

* I'm also replacing the switch and the jacks.

Some adhesives can be made brittle by cold. Can you leave the Advents
in a walk-in freezer overnight? You might find it easier to break out
the crossover board after chilling the adhesive down to sub-freezing
temperatures. A gentle sideways "rap" with a soft mallet and a dowel
might break it free.

If you do this, seal the speaker in a plastic bag before bringing it
outside to warm up to room temperature, so that you don't get lots of
condensation forming on all of the metal and plastic parts.

I have not tried it, but from your description, it may be easier and
quicker to use a spray freeze ?

I don't have a walk-in freezer, but the idea of hitting it with a freeze spray
is appealing. I think I have some.

William,

DON'T disturb the crossover! Remove the woofer (which likely needs
refoaming anyway) and service the crossover in place. In addition to
glue, they are often stapled in place as well. There's not much to the
crossover in these, so it shouldn't be a big deal to service it in place.
