Removable Crossovers

Some people want to install their crossovers in their boxes so that they will be able to remove them later. There are a couple of good reasons for this. Some people intend to upgrade components later, or, if you're like me, you just can't leave well enough alone. This is the method I use when I want to remove the crossovers later. Other people may have ideas that they prefer. Like most anything else, there is no one "best" solution.

Typically, crossovers are mounted to a board and glued to the side or bottom of the box, which works just fine, only you'll have a helluva time getting them back out again. I cut two boards exactly the same size. One of them is drilled out for crossovers components. Then the two boards (the crossover board and the "backer" board) are clamped together and a hole is drilled in each corner through both of the boards.

Next, I take the backer board and put a bolt through each corner. I put a nut on each bolt and turn it down tight. A bit of Lok-Tite or something like that is a good idea - you don't want the bolt to be able to turn in its hole.

The backer board is then glued onto the inside of the cabinet with Household Goop, like normal. When the Goop is dry, I then drop the board with mounted crossover components over the bolts, and tighten it down. It's best not to glue the two boards in at the same time, because it's possible that you may not be able to reach all the bolts once you've got them installed.

When finished, the whole thing looks like this:
