Placement tips for Synergistic Research HTFs


I just bought 15 HTFs and will also be making about a dozen of Ozzie's homemade models.  While I will re-fresh myself with SR's placement tips, and I get that I will have to do some experimenting to tailor the HFT effect to MY listening room; are there any "Advanced HFT Placement Tips" some of you would like to share with us?  Something that might be overlooked by many of us?  Or maybe, just a good rule-of-thumb tip for someone just starting to use these?
The tips could be tips for bring out more highs, solidifying the bass response, placement hi vs low, in front of vs behind speakers, on side walls, at reflection points, behind the listener, on the ceiling above the equipment or above the listener, on the equipment.
Any ah-ha that you would like to share?  I would also be very interested in hearing from people using Magnapans.

OK. Got it!   I'm glad I asked.
If I'm not mistaken yours are fairly similar to the ones jkbtn built.

Not similar, exactly the same. I didn't want a thousand different pieces that didn't fit into one another laying around, so I used his info to good effect. I bought a 1/4" copper cap yesterday, I'm going to use my calipers to measure the ID and see if I can find those same brass 'bowl' beads in the appropriate size. I like the press fit. But I'd like to go smaller and see what they sound like.. 
If you like, I'd be happy to send you a bunch of completed pieces. I have a whole lot of those brass bowls, and copper caps are easy enough to come by. 
It'll save you some time and put those brass beads to good use.
The same people that sell the brass beads you mentioned sell them in 10mm, 12mm and 14mm sizes, and even smaller.

I have found that I like the Cups that you have been using, but in more substantial bases.  I'm starting to write it all up & should be done in a day or two.
