I loved my JSE Infinite Slope Model 2's, (tall 4 way on wheels) a friend has them now, they also use his low frequency Phase Shift Patent.

these are called 'Rosewood', but I believe they are walnut veneer stained red,

I changed my 4 wheels to 3 with rear anti-tipping blocks. Dual wheel furniture casters do not wobble like single wheel axels do. I have those wheels on my current speakers.
this pair, black, you would need to use UPS pack and ship, just have the seller drop them off unwrapped.

notice different inputs, they are the later updated 2A's I believe.
I would verify the bottom woofer is the original dual coil woofer (not previously switched by a prior owner), have a woodworker apply a new select veneer of choice, and good luck finding anything sounding better.
