Sound and vibration control


As an engineer, I wanted to share the results of an experiment I just ran. I have two SVS PB16 ultra subs and my wife got me the SVS isolation rubber feet for Christmas. We have an old house with hard wood floors and when these subs really hit, it does shake these floors. My Focal 1038BE speakers only have spikes for feet, and not so good on old hard wood floors. So, just bored and foing around, I mounted these isolation feet on my speakers, reset them and started playing music.
I was expecting nothing, and was pleasantly surprised to find the base tighten up and midrange actually improved.
I understand physics and this makes no sense. Most of the energy is still being created by the same drivers. Decoupling the speaker from the wood floor with rubber feet should not improve midrange.
Is this some type of “I’m an old man and losing it”, or might there be something to this?
Any one else out there ever try something like this?
Thanks.
