I'm getting a new pair of PMC FACT8's soon, and was told by my dealer to add a piece of granite/quartz underneath the speakers.
I live in a high rise and have cement floors covered with wood laminate. What Herbie's devices would you suggest under the granite slabs...and what should I use under the spikes of my speakers? The speakers have outriggers on them. Also how many devices should I place underneath my granite slabs? Thanks in advance!
