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.

toolbox149,

Keep on posting your results. I agree with you that placing the ozinators too high on the wall does accent the higher frequencies. I ended up placing my ozinators just a few inches higher than my speakers. But my speakers are only 47" high.

Also, try putting them on all four sides of your equipment and speakers.

With the speakers you can also put one on top.

I get the best effect by putting my resonators on the front of my speakers. I also use them on many room treatment devices and the results are stunning. But you need to experiment a lot to find the best placement since some placements can actually have a negative effect on SQ.

Ozzy;
Thanks for the encouragement.  This is great fun!   Also, my sound is getting better.

You mentioned this tip a while back and I've kept the advice in the back of my mind ever since.  Two nights ago, while experimenting with your speaker placement advise, I happened upon a variation which might work out to be a game changer for some of the other readers.  It was a fantastic "Ah-ha" moment for me and is becoming a keystone component of the way I use these things.  I'm working though my idea and should have the advise ready to go soon.

BTW   The Ozinators really sound great!

Thanks,

A quick update,

I am totally sold on the Ozinators, and recommend you purchase the following components and sizes if you want to build some for yourself.

For the caps I went to:
valleyhydraulic.com
Brass 1/8" Female Pipe Cap
Our Products: Brass Fittings > Brass Pipe Fittings > Brass Caps and Plugs
http://www.valleyhydraulic.com/store/pc/Brass-1-8-quot-Female-Pipe-Cap-p1266.htm
They cost about $ .58 each with discounts for larger quantities. Plus shipping.

For the cones I Google:
Hareline Alaska Brass Cone - and buy them wherever they are in stock. They come in packs of 15 for $4.50 plus shipping.
These are 3/8" cones.   Don't bother with any smaller cones.
I'll be testing out some slightly larger cones in a few weeks but these work extremely well.

There are two ways to attach the cones into the caps. My preference goes to supergluing them together. Three little drops around the outer edge of the cap opening - then push the cone down & you're done. The other way is to insert a small ball of Blue Stik/Blue Tak into the cap and push the cone down into the cap.

The superglue models produce a lighter, more airy sound, the Blue Stik models have less pronounced highs which some might find beneficial.

I'll have more about this in a few days.

Enjoy!

Oh, I forgot.   For the superglue I used a small bottle of Gorilla Gel Superglue.  Very easy to use.
