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.

"geoffkait,
I favor using at least 3 modalities. How do you know how many people are getting "mixed results" and are "forced to go back to ... using only a few resonators"? Have you taken a survey of resonator users? How large was the survey sample? Where is the proof for your categorical claim -- upon which you conclude that "trial and error is inherently flawed"? The proof is in your head and nowhere else.

You are right. I will not accept your shallow and flawed explanation. It obviously does not deserve to be accepted at face value. But, as always, you are convinced that you are the forum authority on whatever you care to expound on. No other possibilities exist after you make your pronouncements from the audio pulpit. Who indeed could care less about audio preachers who twist reason into audio pretzels -- in order to stay in the forum limelight to catch new customers? How’s business this week? Lol."

Sabai, you are a victim of the Backfire Effect and unable to deal with any point of view that disagrees with yours. I wasn’t even addressing you. It all comes down to education and experience. Your "modalities" are outmoded. I will leave you where I found you.

Sabai - I've two resonators on the back of my speakers, one on the outer side as one on the top. I've ordered the brass bowls in a smaller size to make smaller resonators. We'll see where those end up..
I made 4 triangular venturi several years back. One each cut to fit my speakers on top. Because my speakers have no right angles or flat surface I had to seal the area between the edges of the device on its bottom surface and the top of the speaker. I used high quality black electrical tape to make the acoustic seal. I did this so the air had to run thru the venturi. The 2 much larger ones I place into the room on the floor venturi facing up. They work the best when Audio Points are used as mechanical grounds. Again I sealed the air gap between the carpeted floor and the device..this time I used wool felt bought on a role. You can tune the sonic impression of the devices by changing the finish on the surface either flat or shiny rough or smooth..the outside could be finished different than the inside. Thats all. Tom
geoffkait,

You break me up. Yes, I am addressing you. Lol.

You have no idea what my modalities are yet you proclaim authoritatively "Your "modalities" are outmoded." One of my modalities is SPL metering. Which makes you ... totally outmoded. Lol.

The geoffkait pot really does call the kettle black once again here ... " you are ... unable to deal with any point of view that disagrees with yours." Talk about the backfire effect. Lol.

Nice patronizing comment at the end, though, "I will leave you where I found you". How about a big group hug and let’s move on. Lol.
toddverrone,

I have one on the top, one on the bottom, four on the back, one on the right side of the right speaker, one on the left side of the left speaker.
