I have 18 HFT's. Two are missing or fell off and are lost. My wife hates them and everyone that comes to our house tries to take them off the walls. I can say that I have not followed the exact guidelines due to the room structure. I probably have 11 on the ceiling beams. I am not putting them on my speakers...sorry, I do not want even a smudge of putty on them. I am also in the process of adding Vicoustic Cinema round absorption panels. I have the Townshend podiums and Shuman Resonators.
In my case, the Shuman Resonators have no impact on my music or sleeping habits. Townshend Podiums a slight improvement in the soundstage. HFT's - can't really say they help or hurt. Please don't say I did not follow the exact placement locations as instructed by SR. Someone would have to prove to me scientifically that those locations are the only place they can be. Now, if the HFT's came in white, then I might be able to follow the guidelines. Fuses are a definite impact on my music. At this point I have so many tweaks I don't know which ones work and which ones don't.
