The UEF acoustic panels were designed originally for recording studios and other commercial installations. The HFT system is less noticeable visually especially in a home environment. I have the the HFT"s installed in two different rooms. The HFT system (using a combination of original HFT, HFT- 2.0, and HFT- X) gives a much richer, fuller, and harmonically complex sound than only using the original HFT's. The diagrams at the Synergistic Research web site (scroll down to find) are quite good at showing where to add the HFT 2.0 and HFT-X and where to then move existing HFT"s. My room was significantly helped by adding HFT2.0 to the speakers and walls. HFT-X (which increase high frequency information) were tried but not needed.
It does take trial and error to really dial in a room but immediate and positive results are easily and quickly obtained with placing about 10 HFT's in any room. This is true even in those rooms already acoustically treated with traditional approaches of absorption and diffusion.
So in summary, the HFT System in where one experiments with the three types of resonators has given me an an acoustically tuned room that is wonderful both sonically and visually.
