HFT High Frequency Transducer

Wait a few days. The glare will be back.

Ok, I'm one of the biggest skeptics when it comes to a lot of tweaks.  When I was at RMAF last year and visited the Synergistic Research room, they did a real time demonstration of the effect of the HFTs.  The room was treated with them and when they removed just a few of them and played the same track the sound stage collapsed and the definition of the instruments was more diffused.  Yes they are expensive for a handful of "audio buttons" but they made a noticeable positive improvement in my system.  The best advise I can give you is try them out for yourself if you can get a guaranteed return policy.  I would recommend 10 to 15 or they have specials from time to time.

I realize your comment suggests this may all be expectation bias or unfounded perception but I don't think that's the case here.  For the past 4 months I had HFTs on only 2 of the windows which I felt were at 1st reflection locations.  I never could hear a change and just assumed they were incapable of reducing the glare.  On a whim I added two additional HFTs to the remaining 2 windows and bam, a noticeable difference that has endured a couple of days so far.  I expected 4 months ago for a positive change and got nothing.  I expected nothing this time and got something.

"Having access to x-ray it is easy enough to see what's going on with these things without taking one apart. None of the DIY attempts comes even close to Ted Denny's design. All they do is mimic the shape. What they leave out is what's inside, what probably (near as I can figure) generates dither."

@millercarbon are you able to share the x-ray files? - You are welcome to send me a PM with the file(s).

I am still following the DIY-approach with quite some success, but I am not done yet 😎

Can anyone share some more light to what is inside the Synergistic Research HFT´s?

As they are using a grid to the opening I suppose it must be something like granules (crystal granules, ??).

I would be happy to know more about the filling.
