Aren't they adorable/scary/cool?
Step 1: Prepare Speakers
But I'll try and recreate what I think is happening from the pictures he provided!
Check image notes for further clarification.
Let's see. . . . first we've got a box type thing that's going to get the facing put on it. The speaker guts will live in here. Looks like we're using some glue and some clamps. (see pictures 1 & 2)
Next get some foam! The blue kind! Most likely found at hardware stores, since that's where you will most likely find Noah. Also I recommend using caulk to put it all together. (see picture 3)
No wait, that doesn't make sense. . . Get some glue in a caulk gun type thing, and go to town. Glue that foam all over that box. Make sure you're using the right size pieces though! Measure twice, cut once. (see picture 4)
Update: Noah really wants me to make sure you know this is liquid nails. I know it's not caulk, but I thought it was funny. As it turns out, liquid nails is no joking matter.
Next, tape all of your seams. But not the whole way. If you don't understand why, I really can't help you, and this step is probably too advanced for you anyway. Just skip it. (see picture 5)
Once the glue is all dry and secure (I'd give it at least 24 hours), start carving your shape! Begin with some rough cuts. (see picture 6) Then you can go in and mark where you want it to be more refined. (see pictures 7 & 8)
Now's a good time to look at your feet. (picture 9)
And ta da! It's done! (see picture 10)
Wasn't that easy?
