This image shows the top brace clamped to the front baffle through the driver hole which keeps it nice and square and from slipping back. The picture is taken from the back of the speaker which is laying sideways.

I glued only the front baffle, the top and bottom braces and one side in the first glue-up. I kept the middle brace and the base off to make it easier to paint. It was easier to do the glue-up while the speaker was laying on its side. This is what it looked like with the first four pieces.

Adding the second side was easy after the glue dried for an hour.
