Synergistic Research HFT + FEQ


I heard this tweak at RMAF and brought it home on a 30-day free trial. Unfortunately it turned out to be a real system killer. I had 20 of the HFTs and tried them with and without the FEQ, using a ladder to put them up and take them down repeatedly. I couldn't believe how awful it was. Made it hard to enjoy my otherwise excellent ~$45k system.

I had a similar experience with their Quantum fuse. Never did trust anything with "Quantum" in the title. HiFi Tuning Supreme fuses, on the other hand, made my amps sound significantly better.

richardk,

I posted this in about the middle of this thread.

"For all you DIY's. I have received many emails to make these items. They are quite simple to make.

I used 1/8" copper caps with a large copper cone from a company called "Hareline" inside. Hareline makes items for fishing lures and can be bought from Amazon.

The caps however, will need to be purchased from a plumbing house. Then just simply glue the cone inside the cap. The cone is a direct drop in. I used Elmer's school glue to seal the cone inside the cap.

Audio Magic also places a crystal in the middle of there "Bells". I suppose you could use (Blu Tack)to hold a crystal in the cap before gluing the cone in it.
Personally I don't think its necessary.

When you place the cones (I used blue tack) on the wall or the equipment, place them in the middle first with one at the height of your speaker, then near the floor and perhaps one up high. If you go to high with them it may accent the higher frequencies. But do experiment.

The others were placed at the first and second reflection points on the side walls.

At the wall behind you, I placed them again in the middle, at floor level, mid and high.

Then from there you can experiment through your room and equipment. Some places they worked good and some not so good.

I must add that I also own the SR FEQ unit which is supposed to excite these things."

If one is not a DIY person, I do hope you will consider trialing the Synergistic family of room treatments. I am extremely happy with the sonic improvement to my listening room. I use the HFT's on the walls and ceiling, and on the speakers. I was just at the LA Audio Show and the sound from their room was outstanding!
I do think rooms need acoustic tuning and the Synergistic Research approach have been much more positive than the old approach of damping and diffusion. In addition my living room does not look like a sterile recording studio.
