Brass nails? I bet they would be easy to find.
Here an example of the Matrix board that I've been working on - some DIY parts and less expensive caps (on the woofer side) to keep costs down.

Couple of ideas for terminals -

MCM has 25 packs of these solder tabs (screen shot)

These could also come in handy:

I used Masonite and enameled copper wire for making my crossover. Drill holes in the Masonite where ever you need a component, and hold it down with a cable tie

Mine are externally mounted... more pics here --> My Morel MTM Project

Odougbo,

Be certain that you have a window open when using that Goop- the fumes could kill you! I know, I've used it, and it certainly does produce a strong bond; however it also contains a lot of nasty chemicals.

Sy, a member here, I think is a chemist. He should tell us all about Goop.

The spay adhesives scare me that stuff will make your head spin.

I used to use household silicon, but they must have change the formulas, it doesn't seem to work as good as it used to.

There's always hot glue sticks, which works very well sealing wires going through speakers walls.

Hot glue seems to be great for securing caps, inductors, resistors and wires to an xover board. It is easier than drilling holes and using cables ties. Can the glue used in hot glue guns damage any of the components?

Thanks,

Probably not. I think you'd have to try very hard to damage a power resistor this way. Try hot melting a small piece of enameled copper then pick it off and see whether it melted the enamel. Even the capacitors should be difficult to damage beyond cosmetic issues.

In my experience, hot glue doesn't make that strong of a bond. Construction adhesive is the best for securing components to a crossover board.

I end up taking them apart eventually:

Here's a hot tip if you do use hot glue, you can heat up the bottom side of the board with heat gun, the parts will slide off (after de-sodering).
