erik_squires, opinions vary.
The very best loudspeker I have heard used a seas exotic driver with the tweeter baffle removed and replaced by an ovalized 4mm solid copper baffle (due to the Young’s Modulus of copper). Which was designed to work in a 2" thick acoustic foam baffle that absorbs reflected energy from the back pressure.
The entire baffle away from the drivers was 2" thick acoustic foam treatment, essentially done to try and mask or remove the baffle from the overall sound the drivers were tuned to produce.
After hearing this I am wondering when someone will make a driver with a cast pure copper basket, as the Young’s modulus of copper lends itself to stop ringing from the basket itself. And yes this has been tested, by using a solid copper backing behind the front seal of the frame and pure copper screws to attach it to the baffle.
Anyway, opinions vary, just like whether or not vibration decoupling loudspeakers from the substrate between them and electronics makes a difference.
Either way, I’m pleased that you are happy with the sound your system produces. So am I with mine :-)
