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,

You stated, "Sabai, thanks for the excellent non-answer!" You’re welcome ... to read my answer again. You will see that it addressed the illogic of your statements. When you don’t like what you hear you call it a non-answer and neatly sidestep the content. Very clever.

You stated, "Here’s a little hint, since I’m in a generous mood ... " How about a group hug after you climb down from your pedestal. Lol.

😳 😳 😳 😳 😳 😳 😳 😳 😳 😳 😳 😳 😳 😳 Photons moving at full speed

So now I’m confused. Photons are the carriers of EM waves, so if we’re talking about an EM radiation with wavelengths 3 - 25 mm, how are the photons at rest?

They’re obviously not at rest. But seeing them *at rest* is the only way you can see them, no?

pop quiz: if photons have zero rest mass, Mo, does that mean they have mass when they’re moving? If so, how can they have mass when they’re moving at light speed?

toddverrone,

It is indeed possible to see photons in motion. This new technology will explain it for you.

You asked, "if photons have zero rest mass, Mo, does that mean they have mass when they’re moving?

What logic leads you to ask this? If photons have no mass that means they have no mass under all conditions. They do not suddenly acquire mass then magically lose that mass. This defies logic -- unless there are laws at work of which I am unaware.

Bingo! Weren’t you the one who said, "I really don’t care how something works as long as it works."? OK, so I admit it was a trick question since photons are never at rest and MUST always travel at light speed c (as Einstein predicted). Also, according to the Lorentz transformations mass becomes infinite at the speed of light c. So the only way a non-stationary photon can have mass is if energy is equivalent to mass. E=mc2. Which of course it is.

geoffkait,

Bingo ... the fish took the bait ... and is once again eager to bestow a gift upon the forum that even Einstein could not conceive (unless he can document where Einstein made this declaration) -- The Law of the Transmutational Nature Photons -- brought to us by the world’s most renowned expert on this unfathomable subject -- right here on the forum -- after a big forum group hug. Lol.
