Platinum Resonator
(Made In France)

The only suitable model for Step 2 is the Basic. Install it on wall behind the speakers at the mid point (in line with but below the first resonator) and don’t exceed 15cm in height when measured from the floor.

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 can 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.

Step 7 uses the Silver, Gold Special or Platinum models and faces the previously installed resonator from Step.3.
