Sound system equipment. Electroacoustic transducers. Measurement of suspension parts Ingestion-build-137917 BS EN 13218 specifies the1 Scope This International Standard applies to the suspension parts of electroacoustic transducers (for example, loudspeakers). It defines the parameters and measurement method to determine the properties of suspension parts like spiders, surrounds, diaphragms or cones before being assembled in the transducer. The measurement results are needed for engineering design purposes and for quality control. Furthermore, this method is intended to improve the
