So, my booth sounds great after some help from this site. Only slight puzzle I'm trying to solve now is... The large Air Conditioning units on the roof HUMmMM. During the summer months they come through in my recordings slightly before any bass roll off. FYI my booth is only double walled on one side, one side a window and extra MLV, and the other side a foam core door with MLV. It's a self modified silver series vocalbooth.com booth.
Now my question!
My booth is actually sitting on the floor on top of a carpeted piece of MDF. Would it be beneficial to set my booth on vibration isolator pads/feet so it doesn't touch the floor?

I did read the rock wool option. It's my understanding the post basically said put your booth atop 2" rockwool.

It sounds like you have a problem with structure-borne sound, where the vibration is in the building structure itself. The best way of dealing with that is to stop it at the source: Instal suitable isolation mounts on the HVAC units, and the problem will go away.
