The 2406 and 2407 both are ring radiators with 2406 with polyester/mylar diaphragms, curiously similar....very similar... to the BMS.
To my eyes, the BMS driver looks just like the JBL driver but without the threaded flange!

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.
