Shahinian Obelisk vs VandersteenTreo

@tomic601 
I think you have something there and taking a pic of the threads is the best way to go.
Post it on the Virtual Systems page.
This is really odd.

you might be on your own till Tuesday, ( put that on repeat in your CD player )

if by some crazy chance I get an answer will post it up

Gentlemen,
Can you please measure the distance between the floor and 1. back and 2. front bottom parts of the speaker: I am trying to determine the length of spikes and cones. What is the difference between front and Back, how much are they tilted in your case?
Thanks!

You mentioned that there was only wood in the place where the threads should go.
I just realized that the previous owner may have removed the metal threaded inserts-Why, I don't know. 
If this is the case, then you need to replace them in order to mount the spikes.

You need those things on the left. Or, maybe some T-Nuts:

Hopefully, the previous owner didn't enlarge the holes too much.
With Wood filler and Wood Glue, you should be able to install them without much difficulty.

I just got your pics and I think I am correct. There should be a threaded insert inside the cabinet.
It looks like the numbnuts previous owner over-tightened the spikes and when he removed them, he took out the inserts as well. No wonder why he 'lost' them.
As I said, you need T nuts, better yet, call Johnny Rutan (send him the pics you sent me) or Mr. V. directly and I bet they will have the proper parts  to fix it.
Can you do it yourself, sure.
BUT, why risk more problems? And, it looks like he broke off some of the bottom of the speaker where they attach.
