Several things going on here. For starters its vibration control. Can’t be isolation because, well imagine perfect isolation: speaker levitating, just floating in space. But the speaker, in order to make any sound at all the drivers have to move. F=ma, every force needs an opposing force, the isolated speaker has only its own mass. Total flop, drain all the energy, a fact proven as easily as putting the speaker on an inner tube or even a couple sheets of sorbothane. So forget isolation.
>>>>Isolation devices act as mechanical low pass filters. Nobody ever claimed it was perfect. Give me a break! The isolation effectiveness of an iso device depends on several factors, including the resonant frequency of the device - the lower the Fr the lower the percent transmission of vibration as you go up in frequency of vibration. AND as we’ve seen in the YouTube video from Max Townshend, speaker isolation has two primary functions - it prevents mechanical feedback to the front end electronics via the floor and reduces speaker cabinet resonance. Since speakers generally don’t have much energy below say 30 Hz isolating them is VERY effective since the percent of isolation for mass on spring devices is higher than 99.9% above 30 Hz. Problem solved! 🤗
