1--- in theory, dont matter what code connections or nature of network... the final phase result is all driver have a outward motion right ?? Wrong


2--- in regard of the theory, I understand your response is according to connection of network : and because the phase of 2121,2420 & 2405 is inverted by circuit network it is important to connect inverted the MF, HF & UHF. See schematic


3--- All this old drivers have a (+) post = black right?? see JBLPRO Tech Library pahse conventions.


4--- Manys folks is expose the JBL monitor is load the LF inverted phase for preload the inside speaker by inward motion. so independently the connection what is final motion of each driver ??? all outward ???

LF inward and all other outward ??? Y


thanks again for light ...of day

You have right... this question is delicate set-up and I study hard for control this parameter with my analyser... but it is easy now to perform this test with filters network load... after response , if you wish , I perform pict of this test.
