Just to chime in...

The esoteric line of woofers from PE was a disaster, with horrific breakup modes and poor spider construction.

If you can, I'd recommend steering away from the esoteric line.

If i made alu cabinets, i'd seal them with epoxy - after powdercoating or anodizing or what ever finish you'd do on the plates.

Really? It doesn't seem totally terrible to me, although the value is low given it seems to performs not much better than most $30-50 woofers. I'd get the RS180 over it any day.

I've owned all 4 revisions of the line, and I was never happy.

YMMV, and maybe I just missed something simple. I used LEAP for the modeling, but no dice on the actual listening experience.

Ideally, the best method would be welding them together. But you can also braze aluminum together with a blow torch, albeit not as strongly as welding and apparently much more prone to failure unless you do it absolutely correctly. Search YouTube for more info if that appeals to you.

The alternative would be to drill and tap (put screw threads) into the aluminum and then assemble more or less like a regular box but with gaskets at the joints to seal everything. You could fasten at the edges or use internal bracing to pull everything together. Study Magico.

However, you might look instead at the original Magico mini and opt instead for just aluminum front and back baffles with the rest of the cabinet in some form of Baltic Birch. It's a devastatingly effective design and I speak from experience.

I got pulled back to this concept but when I was looking for aluminum sheets I decided this project isn't gonna happen as soon as I saw the numbers. I thought it wasn't super expensive but I was indeed wrong. Only one side panel would cost over $200!!! No wonder Magicos are so expensive beside the fact they are a very high end brand!

But I see stainless steel is way less expensive and steel is heavier and stiffer than aluminum. Or is there other factors that make it a worse material for speakers?

And then I'm purely talking about sq influencing factors. I know the enclosures would be super heavy but I don't care. If you take a look at my other threads these speakers have developed to two huge active monsters with DSP driven 2 x 300 watt RMS @ 4 ohm bi amplifiers. If they get insanely heavy, I will make the stands insanely strong, I don't give a damn.
