There's an obvious answer to the following question, but I thought it might be
a good idea to see if someone had an even better idea.

I'm restoring a pair of the original Advent speakers. These were made in late
'75 and have the first version of the crossover. The crossover and amplifier
terminals are on a board that's glued to a hole cut in the back of the
speaker. Other than breaking the board loose, there's no way to remove it.

All parts will be upgraded. The original iron-core inductors will be replaced
with Alpha-Core 14ga air-core inductors. I doubt this will have much of an
effect on the sound -- but the inductors can't saturate at high levels.

There are two obvious ways to install them. One is to simply glue them to the
board. The larger one weighs 1 pound, 7 ounces (!!!) so it has to be glued
down tightly. The smaller one has to be mounted on its "side", so it's at
right angles to the larger. This doesn't provide much surface area for a tight
attachment.

There's no guarantee even the best adhesive won't eventually give way. I don't
want to have to open the speaker in a few years and re-glue the inductors.

The other obvious way to mount them is with locking cable ties passed through
small holes drilled in the crossover board. This alters the speaker in a
visible way -- but it's hardly a big deal.

Any thoughts? Am I missing something obvious?

Thanks in advance.
