Example: Symmetrical stereo arrangements. Cooling While the Hypex amplifier modules that drive the MiniMain12 area very efficient, the speaker still generates a significant amount of heat that must be dissipated. This heat is transmitted to the air via the rear amplifier plate, heat sink and the driver cones. In order to ensure proper airflow, a minimum of 5” (mm) clearance should be maintained between the speaker and any large obstructions. An ambient temperature below CF) should be maintained. Over-temperature may cause speaker to overheat and shutdown.
