Synergistic Research HFTs... This is slightly off topic; however, after TC and the fuses, I decided to try HFTs despite already having 2 pairs of Hallographs in my big system. I built the room with a bad slap echo problem. Frank told me to try the HFTs, I bought Level 1 and 2 installed as recommended. I don’t know how it works so well but while music is playing, the slap echo is 90% nullified (one can clap during the music and faintly detect an echo). I was still wanting a better balanced sound (my wife wanted a more open sound for her rock music) so instead of purchasing the next several levels, I purchased a pair of HFT/HFT 2.0/HFT X speaker kits. These were more difficult to apply so that the sound was balanced due to the unusual driver configuration. However, upon settling on slight changes of 3" up or down, I achieved a balanced sound. P.S. I removed two forms of large damping panels and two rugs/material cover from the room which makes the room look better, just with little pimples on walls and speakers (very tiny sitting 12’ to 20’ from them).
My wife gave her full approval for listening to 60’s+ rock to heavy metal in the room. It has all the spaciousness of the recording venue plus the detail, dynamics and tonally rich full frequency range that the TC and fuses provide. WOW!
I highly recommend the SR HFTs to maximize the TC abilities. However, I also recommend at least one pair of Hallographs behind the speakers. I tried the setup with them removed and I got a very clear, super sharp imaged sound, lacking ambience and air. It was antiseptic sounding yet tonally correct with excellent dynamics. The Hallographs brought in the gorgeous tonal qualities and air/ambience.
