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,

Sorry -- you are completely wrong.

You stated, "See below for examples from Franck Tchang’s website diagram and instructions for using HIS acoustic resonators. The steps of the diagram are specific to his gold, silver, platinum and basic models." Specific, yes, but not exclusive to his models -- as you are implying. Franck Tchang does not say they are exclusive to his resonators, anywhere on his site. Franck's diagrams were obviously made for his products. After all, who makes diagrams for the products of others? Duh. But nowhere on his site does he say his diagrams will "only" be effective for "his" products and cannot be used for other resonators. You are obviously putting works into his mouth. 

You stated, "there are simply too many variables for guessing to be a good choice ...". Guessing, a.k.a. trial and error -- especially when done very systematically -- is one of the most important ways that audiophiles use to improve SQ. Using equipment is another way. Some use both. You may not like the trial and error method. Up to you. You have the right to your method. No one questions that. But others have the right to theirs, as well -- and theirs may be very successful for them.

Your "logical and reasonable" approach is only one of many possible approaches. There are many avenues. I can afford 70 of my resonators for $1 apiece. In fact, that's not "SO MANY". I will be adding more soon. $70 is $30 less than a single geoffkait resonator. I know. I know. Yours are the best in the universe. You can even quote your own site. Lol.

You stated, "So, obviously his diagrams are NOT intended to be universal." Who said they were universal? No one but you either said or implied this. And why is it obvious his diagrams are not "intended" to be used by others? This is one more example of your creative writing ability -- putting words into people's mouths.

How do you know what Franck Tchang "intended" here? Are you a mind reader, playing amateur psychologist once again on the forum? Watch out. If you keep this up you could be charged with practicing medicine without a license. Lol.

I tell you what. Franck Tchang says "email me" on his site. Why don't you email him and get it from the horse's mouth -- instead of from the other side of the horse. And then report back to us what he replies.

Franck's diagrams may be used to good effect in some systems. Why not let everyone decide for themselves instead of trying to tell everyone what to do? Let each person find out what works best for them and what approach or approaches to take. Leaving all options on the table is the very best approach, IMHO. I know. I know. Your way is the best way -- and the only way to get there. Along with your $100 resonators. Lol.
toddverrone,

With geoffkait I am having some fun -- a bit of comic relief -- as well as helping him out by attracting prospective customers. I firmly believe in social service. Lol.

You ask about working on different sizes of HFTs. I am working on this now. I have supplies on order.

Regarding the OP, I have been using 2 sizes of copper cones with one size of copper caps. I have other sizes on order and hope to get equally good results. Frankly, I have been really surprised at how well things have gone so far. The break-through was using Franck Tchang's diagrams. This led me to develop a whole new kind of resonator (2 different sizes). I encourage everyone to let their imaginations run wild regarding how to make resonators and where to place them. Of course, if measuring devices help the process, then by all means use them too.
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.
