BMS 4550 is a powerful 1' professional compression driver that delivers superb sonic quality in a small package. It has an exceptional dynamic range and produces even the most complex music signals with depth and definition.

BMS Elektronik GmbH located in Hannover, Germany is a leading manufacturer of compression drivers. BMS products are used by professional speaker and high-end companies globally.

The patented BMS design remarkably reduces diaphragm weight and inertia. There is no loss of energy required to drive conventional diaphragms. That is why BMS drivers have higher sound pressure level and less dynamic compression than conventional designs.
