Step 10 Create translucent side panels and mate them with the foam shape.

Back in step 6 you guys saw the flat side panels in the cabinet design. These are made of fiberglass/aluminum honeycomb sold by PanelitePanelite. I love the lighting effects that are possible with the honeycomb material, so I figured out a way to use it as a structural side panel, even though it's not really meant for that. It involves pouring resin into the cells near the periphery of your shape, and then cutting through the filled cells with a jigsaw. The dark areas in the flat panel are those filled with epoxy resin.

I don't recommend working with the honeycomb because it's a very expensive material. Frosted acryllic panels would also be very beautiful when backlit properly. Or you could just use the fiberglass itself, which stays pretty translucent, and can be dyed with translucent color dyes. The advantage of using the fiberglass is that there is no mating process between side panels and the main form. The disadvantage, is that you would then have limited access to the inside of your cabinet unless you create a parting line. You'll have to reach through the woofer holes. Not a big problem if all the objects you're planning on putting inside your cabinet (amplifiers, lighting, etc.) are smaller than this hole.
