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.

If you’re using panels the acoustic waves will obviously set up in the room quite a bit differently than conventional box speakers. Thus take any diagrams with a grain of salt. Also keep in mind Tchang’s diagram is indicated on his web site as pertinent ONLY to his Silver and Gold tiny bowls, so I suggest using the diagram with that in mind. Of course the best way to locate the ideal positions for any resonator(s) is to employ a test tone and SPL meter.

Where did you find info on Ozzy's diy HFTs? I'd be interested in trying these, but not if I have to buy them...

Todd;
You can find out about Ozzy's DIY resonators (or Ozinators, as I am calling them) if you read the thread titled. "Synergistic Research HFT + FEQ".  
I think Ozzy started to write about them on page two and had a lengthy conversation with Sabai about them.

Ok, here is a recap of my posting from 2014.

"For all you DIY’s. I have received many emails to make these items. They are quite simple to make.

I used 1/8" copper caps with a large copper cone from a company called "Hareline" inside. Hareline makes items for fishing lures and can be bought from Amazon.

The caps however, will need to be purchased from a plumbing house. Then just simply glue the cone inside the cap. The cone is a direct drop in. I used Elmer’s school glue to seal the cone inside the cap.

Audio Magic also places a crystal in the middle of there "Bells". I suppose you could use (Blu Tack)to hold a crystal in the cap before gluing the cone in it.
Personally I don’t think its necessary.

When you place the cones (I used blue tack) on the wall or the equipment, place them in the middle first with one at the height of your speaker, then near the floor and perhaps one up high. If you go too high with them it may accent the higher frequencies. But do experiment.

The others were placed at the first and second reflection points on the side walls.

At the wall behind you, I placed them again in the middle, at floor level, mid and high.

Then from there you can experiment through your room and equipment. Some places they worked good and some not so good.

I must add that I also own the SR FEQ unit which is supposed to excite these things.

Yeah, I figure working with the Magnepans is going to be a challenge.  Especially, since I have a quad set-up which means I have four Maggie 1.7s to deal with, plus two large subwoofer enclosures.

I like Ozzy's sugestión of attaching some of the HFTs and some resonators (Ozinators) around the sides and top of the speakers themselves.   Attaching them to digital components also sounds intriguing.
