Sabai, sorry but you’re wrong. See below for examples from Franck Tchang’s website diagram and instructions for using HIS acoustic resonators. The steps of the diagram are specific to his gold, silver, platinum and basic models. Even if resonators are in the same shape and geometry as the original Acoustic Resonators (which your cheap knock-offs almost certainly aren’t) different materials, metals, ceramics, whatever, will have different reactions in different positions. Of course it’s your option to guess but IMHO there are simply too many variables for guessing to be a good choice. That’s why the only logical and reasonable approach is to use a SPL meter and test tone(s) of your choice. This probably explains why you had to use SO MANY resonators. Eventually you will find the ideal locations by accident. Wake up and smell the coffee! 😀
[Also, note that caveats are provided in his instructions, such as this location is good for small room with big speakers. So, obviously his diagrams are NOT intended to be universal.]
Step 4 should only use the Silver or Gold Special models. This position is very effective to open up the corners. The wooden base must be installed on the sidewall but butt right up against the front wall. It should sit slightly lower than the center resonator of Step 3 but no lower than 5cm from the ceiling.
Step 6 should use the Gold or Platinum versions. Install these units on the side walls as high as possible. Relative to your listening position, these resonators should align within a plus 100cm, minus 50cm window in front of and behind your chair. These two units cancel the sidewall reflections and reduce low-frequency resonance.
The Silver or Gold Special models are suitable for Step 8. This pair should be installed as high as possible on the sidewalls and butt right up against the rear wall. This location is very useful for smaller rooms with big speakers.
