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 actually tried hard but each time with each different placement/setup I had no doubt I was hearing absolutely no difference in sound quality/stage. I am no Mozart but I’ve reached these conclusions based on what I was hearing. If you are interested in these resonators (before you go any further to spend money and time) send me a private message. You can come on by and pick them up if you live in southern California. I am a retired mechanical engineer.

The single biggest improvement I’ve ever made (besides buying new CDP, amp, speakers) resulted from re-positioning the speakers so that the drivers were way out in front of the big screen TV and the front wall… dramatically improved sound stage, blossoming in space between and behind the speakers. Oh and, draping a thick fleece blanket over my Samsung TV really worked, resulting in a little more defined sound quality. It only made a little difference but definitely noticeable. The problem was it didn’t look good so I stopped using it.

Question to those of you on this thread? Are you using the SR FEQ (or equivalent RF pulse generator) along with your SR or home build resonators? The FEQ really is essential to activate the resonators but is itself mighty sensitive to a) grounding (if you have more than one FEQ make sure they are grounded exactly together) and b) footing -- after much experimentation I have mine on custom symposium bases, the bases themselves on roller blocks

I also experimented with placement of my pair of FEQs and after much to and fro ended up with them behind my speakers -- I also use an Atmosphere which is placed between my speakers

Anyway for those who like the effect of their HFTs do investigate adding some form of activator

Your speakers compression waves are the activators. Any thing in your room act the same way..its all in the touch. Tom

I am using the FEQ and I also have 3 Acoustic Revive units (RR77,777,888).

In my room the ozzyinators  work really great! Placement experimentation is the key.

Wow, that’s intense. Can you tell us how the activator thing, SR FEQ, works? How can those resonators be possibly activated? Activated vs non-activated resonators??? The inventor must win the Nobel Prize in Acoustics (or in Snake Oiling).
