I ordered the driver, bought the wood, and will be starting the cutting this weekend. This will be a bit of an unusual build. Some will say that it will be ugly, but the wife has given her stamp of approval, and more importantly, I like it. It should be a nice step up from my current Titanic III 15”.
The driver will be a Maelstrom-18".
Amp will be a Behringer EP4000.
EQ will be a Behringer DSP1124P Feedback Destroyer.
Using ¾” MDF to make a 5.75 cubic foot sealed enclosure (internal).
Walls to start at 2” thick and then be sanded down to maybe 1&3/4.
I don’t have any graphics software but have managed to put something together with Excel & Word. Here is a cross section of what it should end up looking like. It will be 30” wide by 35.25” high. I have noticed that with Word, dimensions will be skewed from one computer to the next depending on settings. The width should be 85% of the height, so if you want to see it scaled properly, you may need to do some stretching of it.
A few people on another site were saying that I needed more bracing. Here is the new design. Anyone feel like helping me get this monster up the stairs when it's finished?
Cutting begain last weekend. There were a lot of setbacks at first, but now it's moving along well. I have 15 rings cut and the rest have all been drawn out. Just need to connect the dots with the jig saw and then I can start stacking.
Shouldn't be too bad to sand it down if you have a good belt sander and some aggressive belts. Use a dust mask. Hook a shop vacuum to the belt sander dust port.
Might be a cool idea to build a "potters wheel" with a big lazy Susan bearing so you can let the egg spin as you grind it down with the belt sander. Might get more consistent profile that way.

This is the first coat of China Red. It looks more orange to me. The next coat id Red Oak. It's starting to look more like the Piano Rosewood that I want it to match. Once it dries it will get a coat of Red Mahogany and then a bunch of clear-coats.

I did use a belt sander though. Took the better part of a day to hit it with 40 grit, 80 and then 120. After each primer and paint coats it gets hit with 220.
Much like you, I tried the router first but ended up with the jigsaw. I saw that you cut your face-plate using the same attachment I picked up for circles. It did a fair job for me. I'm not the perfectionist you are, but it still came out OK.
I'm curious how you came up with the correct size/shape of an egg before you divided it into your 3/4" mdf sections. I mean, how did you know how much to increase or decrease each diameter to get the perfect egg shape in the end?
You've given me an idea for my next build. Here's the prototype...
