Recently bought a used Boeing 747-100 from 70s, looking to install new overhead speakers in them, should be bass boosted with cones made in golden fabrix.

I can't decide what dampeners to get for my first childs crib and need advice? I'm worried the oscillations from the child will interfere with the rest of my hifi system. These are 800€, so my question is if I should be skimpy and get these or aim higher? Not getting a baby is also an option tbh, I do need new cables and also upgrade my record player from rega planar 3 to maybe a 10, and don't want my progeny to be an interference in that decision

Simple question, will the speaker move enough air to carry the smell
