You should actually place Varitunes similarly. Placing panels where they are convenient won't really always work, but large traps like the Varitunes work at a lot of positions in most scenarios anyways (similarly with a lot of large absorbers) |
We are not talking about Varitunes here, please don't go there. Let's stay focus on Limp Mass Absorber.
Let's be specific here, I don't understand why you involve 55Hz resonance or null. I said, I have according to my measurement a peak 30Hz, null 50Hz, and peak 80Hz at LP, period.
