One answer was to couple with Blue-tack - the second was to use Sorbothane to isolate the speakers and the third (and the most confusing) was to use a combination of the two. As I said, this is one of those questions everyone seems to have a strong opinion on. The stands are filled with sand, they have spikes with rubber shoes to protect the floor. I'm going the Blue-Tack route to begin - it makes the most sense to me. I'll post results.
To Couple or Decouple Bookshelf Speakers to Stands?
Just bought my first pair of bookshelf speakers (Focal Aria 906) and stands - have filled the stands with sand. Should I use sorbothane pads to decouple the Focals OR Bluetack them to the top base of the stands? I've asked 3 friends and received 3 different answers.......
