Acoustic Elegance TD18H active woofers

100L sealed boxes in progress for Acoustic Elegance TD18H active woofers. Built with 18mm marine ply. Being low cost imported ply there are obvious shortcomings - voids can be seen in the cuts, but at around $80/sheet there isn't much to complain about.

The bracing is very simple. Just one horizontal and vertical matrix brace with a driver cut out. It isn't necessary to cut lots of holes in the braces, the volume gained is minimal, the braces are weakened and more effort is required.

Cutting braces:

Clamping and gluing bracing together:

Cutting driver holes:

If one cares about the appearance of the cut out that will not be seen, a router can be used to cut the full depth. However, these days I prefer to do things quicker so I start with the router, but don't go full depth. I then cut with the jigsaw. (That isn't me above, as always I'm the one taking the photos.)

Progress so far:

This box is very simple. The outer baffle needs to be added, then the other fives sides and the box is assembled.
