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
How bout a tapered enclosure Perry?…..Aperiodic that uses a resistive vent out the back?…..reduces the impedance bump of the driver and makes XO work a little easier.
Here's anouther example of a folded wedge, I've made a few WAW (woofer assisted wideband) speakers, so use these for the full range driver. They're so affective, you can use them without any stuffing.
I have made several builds with a multichamber aperiodic sealed alignment. This eliminates the unloading below aperiodic vent Fb, and yields an ultra-low Qtc sealed box with very reduced Fs magnitude.
Anything from 66/33 to 50/50 percent volume split.

How did you get the volume, just work out the close box volume, and add a divider, or is the second chamber additional?
Look at 'matka speakers'
Earthen pots with speaker at opening.
Excellent for casual use, careful about breakage, the pots are quite cheap though.

I've used flower pots. They worked great. I damped them a lot but after the pot was glued in it didn't ring at all. I'm somewhat surprised at the use of plastic traffic cones. It's a DIY thing that more people should investigate.
I think so they are stiff plastic not the rubbery ones, but they are hardly stiff. Considering that horn guys say they can hear different horn material I think plastic cones are a bad idea for a midrange enclosure in a woofer environment. YMMV
