Check out Kenrick Sound on YouTube.
https://www.youtube.com/channel/UC5b1QVECAqmbXKgPJHgFNgw Almost any of the videos will show the speaker and how they fit on their stands. They make a simple but functional looking wood stand that can accommodate speakers much larger than yours. Then see if you can have some local talent make something similar for much less than they'd charge (their cheapest is around $650 for a speaker smaller than yours).
Here is a better look at them:

https://deercreekaudio.com/t/steel-speaker-stands They've expanded the number of stands since I got mine but I don't see where they have one specifically for your 4367. They will do a custom order but it may be too dear in cost since it's not in their inventory and it's made by a local craftsman and artist. But you'll never know until you ask.
Also, don't be fooled by the simplicity of the design. The one I have is simply steel with a deadener internally added and uses nothing more than felt feet and padding on the steel frame for the speaker. Not at all like the cutting edge stuff out there and yet I have the most stable, layered and exacting sound stage ever. Just goes to show....
All the best,
