@torke Glad you we're able to solve your issues. Which isolation footers did you have before and when you decided to couple them how did you do it? Are the speakers on spikes now?
There is another thread discussing footers and isolation here... https://forum.audiogon.com/discussions/footers-under-new-speakers
I made a comment about how isolation or vibration de-coupling may do more harm than good when it comes to bass weight and impact.
