There is no way to really "test run" a ten π speaker before the expansion foam is installed. Bracing and filling with expansion foam are esential. There are lots of large panels in this system, and they simply must have adequate bracing or the speakers sound terrible. Some previous threads that discuss proper bracing include "Bracing", "ten Pi injection foam - VERY IMPORTANT" and "Bracing: expansion foam".
