To my eyes, the BMS driver looks just like the JBL driver but without the threaded flange!Originally Posted by edgewound
Now If JBL is really using a BMS driver, it isnt difficult to have their driver made with the threaded flange and chamfered front! But the backcaps look identical! Even the connectors!
BMS could make it for JBL to JBL specs, and possibly the only difference is the diaphragm material.
