The SS3BK-24 is a 24" fixed-length speaker pole intended to fit into the top of the JBL Professional PRX618S subwoofer. The SS3BK-24 uses the sub as a base for nearly any mid/high speakers having pole mount sockets designed to accept a 35mm pole.
Future JBL Professional subwoofers may also accommodate the SS3BK-24 - check the applicable Users Guide or product literature to be sure.
