I want to get vibrapods to put under Spendor S100 speakers that weigh about 80 lbs each. They must be placed on a built in bookshelf. I was thinking of using both cones and isolators. Will this improve things and can I use the #4 isolator? How does the 30 day trial policy of Vibrapod work?

A combination of Vibrapod Cones and Isolators #4 will work very well together under the 80 lbs speakers. If you were to use the Isolators alone, we would suggest the #5 pack, as it withstands a greater weight. But, in combination with the Cones, the #4 pack will suffice. I think you will be quite pleased with the result. If however you decide to return the items, you have 30 days to do so. A 15% restocking fee will be assessed for the pack of Isolators.
