A loudspeaker is a system of interdependent decisions: driver behaviour, cabinet geometry, amplification and the room. Our work brings those decisions together.
Define the role of the speaker before choosing the components.
Treat amplification, filtering and the enclosure as one system.
Keep design targets, modelled behaviour and measured results distinct.
Choose by role, scale and system requirements. Each model has a distinct place in the collection.
