Has wheels and impedance selector.
Built for two 15", clearly a bass box with big ports.
Belonged to Black Oak Arkansas, and still labeled.
I also have a JBL 4647A box.
I have plans for it, but if you have a more compelling idea...?
Materials and expertise...whether you need them or have them to share, you can let folks know here.

I would put the cheapest 15's in there you can find because the playadust gets in the voice coil and abrades it. Then glue some small lightweight mirrors to the cone of sufficient size to be illuminated by a laser at cone travel extremes. It makes a nice lissajou-like pattern on a wall surface, also nice beam through the dust. Of course laser safety observed.
