Shahinian Obelisk vs VandersteenTreo


HI fellow ’goners.
I own the Shahinians, thinking of upgrading to the Treos. The Obelisks sound a little smallish for the room... And the room is not square, it's a big living area of a house, with access to the second floor's roof. 
Will this be an upgrade or just a sideward move?
Room approx 60m2, driven by Musical Fidelity A5.5, 250wpc at 8Ohm (thinking of replacing this one too).
Mostly jazz and acoustic music, less frequently - classical and pop.
Thanks!

Bob,
The thread is there, it’s just not visible on the pics. The back spike hole has no metal inserts anyway.

So, can you thread your bolts into them?

Yes, but the front ones are toо feeble and not deep enough to hold the tilted speaker - without proper support by the washers, of course. I even broke part of the thread.

The back hole will hold the spike, though, as the cone is pressed directly against the speaker bottom, so no sideways pressure on the wood.
I have the Diapason ensemble that I'm trying to sell and the process scared me straight.  I had to list a bank account and then it costs $100 to post the sale.  Is this correct? and what are my changes of finding a buyer?  I'd be glad the pony up the money, but I'm selling for a deceased person, and his wife cannot handle the process.  Sorry for interrupting the thread. Any info would be appreciated and if you can redirect me to somewhere, that's cool too!
