At the InDIYana event thanks to @wolf_teeth I picked up some Dayton RS125-4s (5” mid, which is what the flower pots are for) and SB Acoustics SB19ST-C000-4 tweeter, which I’m matching to a 3D printed waveguide. I decided to make a 3-way using a Dayton knock-down enclosure.
Woofer is a GRS 8SW-4HE which is a very well built long excursion subwoofer.
I use whatever wooden bowl that fits and is cheap on Amazon….typically Acacia wood….i simply sand the rim flat and glue it to the inside of the baffle.
My recommendation would be if you can distort the pot/enclosure with minimal force in your hands, don’t use it as it will likely distort and resonate

My go to are PVC caps, very rigid and super easy to route out a rebate to mount them, e6000 glue holds them with enough force that they have to be hammered out (I can barely get them out once they're installed).
I've used the traditional (clay) plant-pots for this when testing drivers, and there isn't much to dislike aside from the weight. People worry that they can ring when tapped, but (of course) when the open end is glued to a baffle, any bell-like characteristics immediately vanish. The result is an instant solid shell, with tapered sides as an added benefit.
I prefer a tapered wedge, here's an example of a folded tapered wedge
