Placement tips for Synergistic Research HTFs

Todd, jkbtn,
Hang in there guys. Unfortunately, work around the house not to mention work itself, is casing delays in my ability to get out my final report. The scope of this final report is also adding to the delay as I discuss constuction, material sourcing as well as the head-to-head testing results.
the reason I ask you to hang on is, while jkbtn had a good idea as far as construction goes; when his resonators were compared to other self-made types of resonators they finished way at the back end of the pack. They didn’t even make the cut down to the "six finslistist" list of resonators I re-tested this past weekend. So, I can understand jkbtn could become discouraged. But jkbtn’s cones were a huge help, as you will see.
Todd -in my testing, going smaller did not make results better. To my ears the smaller the self-made resonator the more minuscule the effects.  
You can see the six finalists if you look at my System Pictures, here on Audiogon.
So don’t get too down on these, don’t give up, and don’t give/throw away any of your parts. Trust me - I will get this report out.

Hey, no worries and no hurries. Jkbtn, I’m sorry for being condescending. I have no problem with you not hearing a difference and moving on. But attacking products as snake oil that you’ve never tried, or assuming that, because you didn’t hear a difference, they don’t work and the rest of us are fools is a bit condescending to us.

I was sceptical of cables and outlets. When I heard the difference they made, I decided to not attack things that I may find ridiculous any more. I simply decide if I want to try them, then decide if they work for me. If not, I’ll share my experiences. But I certainly won’t go on a mission to save everyone from snake oil.

Toolbox - i just looked at the pics of your resonators. It's funny, I just went to Lowes last night and bought 3/8" OD compression caps and made some resonators with them as bases instead of the 3/8" copper pipe caps. It looks like you are using the same thing! I think I like the sound better with the brass compression caps. Plus, they look better. Ha! The difference in ours is that I crush the brass beads/bowls into the caps using a bench vice, instead of gluing..

Interested to read what you heard!

Todd,
I have stopped pressing my cones into bases and now only use glue.  I would be very interested (if you have a couple of jkbtn's 14mm cones) if you would take some Elmers and build two or four temporary models with the cones sticking out, and test them against your press fit models.  I'd love to find out if what you hear is the same as I heard.
Oh, and yes, I agree.  I'm finding out that big cones are the best and a big bottom can help too.

Toolbox - I posted some pics of my resonators on my system page. I filed the bowls down so they are flush with the copper caps. They look better and sound the same. I think they sound slightly better, but I think that’s completely expectation bias. I’ll get a few more copper caps and make some glue in resonators and report back. I think I’m single handedly depleting Lowes’ stock of 3/8" copper caps!

What’s blowing my mind with these resonators is how effective they are. I was incredibly sceptical. But man, they’ve helped open up the soundstage loads. And, more importantly and surprisingly, they’ve solved a massive resonance problem I had. My left wall is half floor to ceiling glass doors and half large window. That’s a lot of glass. But our design choices preclude heavy curtains, or, really, curtains of any sort. With my current setup of 18 HFTs, the resonance in the high mids and up is gone. Nice!
