Thanks Ray
Had a few questions
How did you use glue in your nine point cell, just small blobs around the 9 supports?
When you say crept sideways, was that due to the silicone's elasticity?
Any harm in adding silicone at the sides?
What should I look for to see effects of adhesive mounting?
Could you explain the relation between eq mounting and edge supports and why it won't work?
Thanks
