FMJ units are very high quality hi-fi electronics.
To allow them to deliver their very best performance, a little care should be taken about where and how the units are sited in your listening room. It is best if the units are not stacked on top of each other. Your FMJ dealer will be able to advise you about these. These stands allow each unit to be placed on a separate shelf. In all circumstances, there must be sufficient space around the units to allow adequate airflow to prevent the units overheating.
