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.

Damn toolbox, you are one productive human! This thread has become quite the treasure trove of info. Since you seem to rate the version of the resonators I’m using the lowest, I’m going to pick up some heavy brass caps today and make some using those. I’ll still go the press fit route and may try the glue ins later.

@ozzy I haven’t tried them on top of the speakers yet. I’ll do that. As for the bb or crystal, I’m assuming you glue them in?

Crystals. Ha. We’re getting all new agey! What’s next? Dream catchers? Ooh, that’s not a bad idea for diffusion...
Dream catchers? I thought that’s what this is all about. The ability for us to go to our listening area and catch a dream of some musical performance. I was dreamin’ pretty good last night.

I’d be very interested in reading your opinion about the heavy brass caps coupled with the 14mm jkbtn brass cones. You WILL need some kind of glue to assemble them. The cones are too big to presss fit.

Throughout this whole episode, I’ve been trying to figure out if the bigger bases help produce better sound, or if it’s the big 14mm cones, sticking way out of the bases that add the most to the sound. While I’m kinda leaning toward the idea that the bigger bases have the bigger impact - I could make an argument for either point of view.

The one, big drawback to my favorite resonators is that they ARE heavy. It takes a pretty good wad of Blu Tack to hold them in place. Every time I head to the listening room for some music, I start out by making sure all eight resonators are still in place. Luckily I have carpeted floors. It’s not uncommon to find one on the floor.

Hope you’re having fun.

My Brilliant Pebbles was the first comprehensive crystal-based (all crystal, actually) audio product to address all aspects of the audio system and room, and was introduced at the London HiFi Show way back in 2003 (WHOA!!) which was in fact some years after they were an actual product.  I suspect I might possibly know a little more than the average bear about crystals. Fire at will.

I agree with ozzy who says that "placement experimentation is the key." I am using 8 different kinds of DIY resonators in my system based on the HFT idea, with at least one more to come. I have also designed a unique resonator in 3 sizes, not based on the HFT design. I think it is becoming clear that the challenge is to find what works best for each one of us since each of us has a different system and a different room, along with different goals and budgets.

Whether this entails using measuring devices, guides, suggestions, diagrams or your own creativity, or a combination of some or all the above, is an individual choice and may depend on many factors. Since this can involve walls, floors, ceilings, furniture, components, speakers, wires and cables, tweaks and accessories the possibilities and permutations are nearly endless, depending on how far you want to take this down the road.

If you add magnets and crystals to the mix then you're in for the long haul. Obviously, time and patience are the two keys to success. It can take months or even years to develop all this. Since everyone's systems and rooms are different, and since our goals may also vary, it is clear that there is no formula that will apply to all situations. This is very much an individual endeavor. It is up to each of us to discover what works best in our own situation. Ozzy hit the nail on the head regarding placement experimentation.
Toolbox149,

Some of my resonators are also very heavy and find their way to the floor from time to time. I always keep extra Blu Tack handy.
