I don't know what speaker(s) you have.
Right off the top of my head I can't remember if the LE5-2 mid-range driver is a positive or negative driver............
BUT, it makes NO difference IF you have either the L100A or L100A (late) with the N100 network working from what we have
Both tech sheets show them to be EXACTLY the same EXCEPT for the woofer used and an "out of thin air" polarity change between models as indicated by JBL to address the "I have no fu&king idea" part
And I say "out of thin air" because NOTHING ELSE IS SHOWN to be different.
Is WOOFER CONE EXCURSION DIRECTION all that defines the difference between an L100A and an L100A (Late) model? Because with what data we have that would APPEAR to be the case.
And that is why this stupid ass question which has never been answered still irritates the shit out of me.
I can tell you this much and it coincides with how my L100A (Late) production L100s were factory wired to the LE5-2s, the owner's manual illustration above and (we assume) the tech sheet(s), UNLESS someone or some tech tampered with them:
The WHITE WIRE coming off the L-pad #2 lug is to be attached to the RED terminal of the LE5-2, on BOTH variants, again, IF, the chart is correct AND the illustration in the one and only owner's manual there seems to be in circulation applies to all models with regards to the LE5-2 mid-range driver as BOTH tech sheets are IDENTICAL sans the woofers.
But I reiterate, the tech sheets do not indicate TRANSDUCER terminal color code, ONLY wire colors from input terminals through the entire network until we get to the business end of things where with the exception of the tweeter's fastons, your guess is as good as mine as for original intent and we are back to relying on how JBL did it "most of the time" with anything wirewise BLACK going to BLACK terminals.
We simply have to assume it is correct (the nice owner's manual illustration) and runs consistently true through ALL incarnations of the L100 (reflects accurately that they were all assembled this way) But I do not KNOW this to be a FACT:
http://manuals.harman.com/JBL/HOM/Te...L100A%20ts.pdf
http://manuals.harman.com/JBL/HOM/Te...0LATE%20ts.pdf
And this is the part that (still) pisses me off. Why in the world are there TWO versions of the SAME speaker identical in EVERY aspect except woofer model/VC polarity?
Actually, NOT EVEN THAT as the only FUNCTIONAL change to the system, again assuming our data to be correct, was the direction of woofer cone movement. (technical improvements/refinements between the two woofers notwithstanding)
Was a subjective decision made that wiring the LATE L100A to be an "outie" just sounded "better" than the standard L100A, which going by those tech sheets above is absolutely the ONLY difference between the two systems.
OR are we missing a part of this puzzle still?
I understand that going from the 123A-1 to the 123A-3 that the VC polarity "issue" would need to be addressed, obviously, their respective behavior is different, but as your question DOES suggest, then we have in fact CHANGED the relationship between the WOOFER and the MID as everything else remains EXACTLY the same...................unless?
I mean how fu&king hard would it have been to expend 3 more molecules of black ink and identify the actual TRANSDUCER'S TERMINALS?
This bull shit L100 wiring hubbub has exacerbated me for too god damned long now..............I really wish I could find a manual that reflects what's ACTUALLY in MY specific pair and or a COMPLETE system schematic complete with the small detail of which fi&king TRANSDUCER terminal to use with which wire. I DON'T HAVE ANY YELLOW WIRES!
Based on what we do know combined with what we have to assume, wire as described above because apparently JBL didn't seem to think it mattered...............or did they?
I don't know; I have mine wired with the white #2 L-pad lug wire to the red terminal on the LE5-2
It's just incomprehensible to me that such a fundamental piece of information regarding what is possibly THE most iconic home loudspeaker system of all times is so elusive, in ANY and ALL of it's variations
Very frustrating, especially when I can (fairly easily) find out how many times the production line workers took a piss during the 8:00 AM Klipsch Heresy piece of crap shift run, on any given day back in August 1977 if I really needed too.......................and probably, with just a little extra effort, what P.W.K had for lunch that day
