Depending on the case of application and the required maximum level three different version are offered. Beginning with compact 12 and 15-inch bass reflex systems to the high power subwoofer with 18-inch long throw driver and cardioid technology harmonise technically and optically with our mid top cabinets from the TS-series. These systems feature high dynamics and low distortion.

Besides the technical advantages of the subwoofers from ME Geithain all equipment share a robust cabinet from ply hardwood, impact-resistant coating on polyurethane base, pocket handles and a top hat fitting for the attachment of an adjustable pole. The front is secured against damages optically neutral with a perforated steel grille fronted by acoustic foam.
