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.

I’m interested to hear how your experiments turn out. As soon as a saw what these things are, my first thought was that there should be different sizes for different frequencies and their harmonics.

A very perceptive question, why shouldn’t there be different sizes? Why are all of the original Tchang tiny bowls all the same diameter? Why wouldn’t he have a whole range of sizes? And why are all tiny bowls from other manufacturers all approximately the same diameter as Tchang’s? Did they all just blindly copy his? And why is bass performance affected so much by the tiny little bowls? Answers at 11

I'm surprised to know that there are people out there actually buying this stuff.
Oh I'm curious about this big parabolic resonator ($2500).
I am trying to build my own using guitar cone resonators ($10/pc).
I know it would probably be just another perceived placebo effect though.

Thanks for posting the link to the large resonator. Of course it should be mentioned that’s pretty close to the size of a relatively large medium Tibetan Temple bowl. Oooooo!

toolbox149,

Ozinators... I like the sound of that!  Will you also be using the 1/8" copper cap?

Yes I'm going to try that.  I don't know if they will fit together though.  Stay tuned.
I like Ozinators because it's a nice tip-of-the-hat to the first guy I saw doing this, and also it keeps you away from anyone hastling you based on trademark infringement.  And according to Geoffkait, they resonate. 

Todd,
Hold off on ordering very small cones until I get my caps.  I ordered the cones from Flyfishers.com yesterday and they arrived today.   The small cone sizes are VERY, VERY small.  I want to see if they will fit a small cap before I tell you to procede.
