HFT High Frequency Transducer

I just wanted to post on this old thread the wonderful results I've obtained placing one HFT in the center of each of the four 7.5ft tall x3.5 ft wide glass windows that align side-by-side and make up much of the left wall of my listening room. Completely eliminated the glare.  I use them in conjunction with standard placement of 10 other HFTs in the room and HFT 2.0's on my speakers.  I also have traditional GIK and ASC absorption and diffusion in the room, however the glare remained until I added the HFT's to the windows.  Tamed the glass resonance perfectly while enhancing the overall imaging and soundstage IMO.

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’ve been treating glass windows and glass doors since Gandhi was a Boy Scout. First Brilliant Pebbles, then Flying Saucers for Windows. 🛸 🛸 Power to the Pebble! ✊

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.
