How to Build Custom Speakers

Step 12 Glue in the support braces

If the initial glue-up of the cabinets is dry, it's time to glue in the support braces. As before, apply a thin bead of glue to both surfaces and slide them into position.

*Note*

The support braces can be glued in position when the top, bottom and sides are glued. It adds a bit more work to an already busy process, but it allow you cut slots and insert biscuits on the supports to join them to the sides, something that can't be done if they're glued in on their own like I'm doing here. Since their position isn't absolutely crucial like the other parts of the cabinet are, it's not a problem do wait for for the initial glue-up to dry, and do them on their own.

The subwoofer supports are shown below first, followed by the rest of the speaker cabinets.

I usually build 3 sides at a time, rather than 4 or if 4 I try to make it 2 adjacent rather than opposite sides... that makes any bracing or internal baffles much easier to install if you don't have 2 sides on the box yet.

If I get stuck doing them in the order that you're doing them, then I either use a set of the quick grip clamps like you have in a few of the pictures or pipe clamps with the jaws reversed to spread/slightly bow the box sides. I'd bet that would give you enough room to use the small biscuits that you're using.

Also, for most speaker designs you'll want to ease the hard corners of the support braces to minimize chances of wierd wave reflections in the box/standing waves/weird tuning issues.
