Back Stage Technolgies copied the idea of a concert speaker system - i.e. the complete system was made up of many smaller systems that were bolted together. The foam machines were made in such a way that they became modular and, like the speaker systems, could be bolted together on location and suspended in arrays. In this way they could create a foam generating system that was both portable as well as giving them the flexibility of suspending as many "heads" or "generators" as they wanted.
The company reports that the MBN foam generators were "easy to handle, very reliable and had an enormous foam output".
