Internal wiring on L100A is incorrect
Yes I am a newbie and a mechanical thinker.
A few years ago, I "cleaned up" my L100's with N100 x-overs. I cleaned and lubed the L-pads with DeOxit and installed new binding posts and 12 gauge wire. I suspicion that I did something wrong with one of the pair even though they sounded better than before (L-Pads I am pretty sure). I bought a test DVD and the two JBL’s sound partially out of phase with each other is why I think I screwed up. Reversing the leads doesn’t exactly clear it up either which makes me think that I tried to “fix something that wasn’t broke” inside and have possibly the mids out of phase.
I have the Schematics for the N100's and have read tons of information here, which I appreciate immensely. I may be under some wrong presuppositions regarding the wiring of speakers and JBL’s in particular.
My old assumptions:
RED= +
BLACK = -
Yet I know in house wiring that Black is hot and white is common.
Power flows from amp/receiver out the RED post and comes back to the black post. If I want to put a resister in series to attenuate (going from instructions), I put it on the +/RED side.
Capacitors can be wired either way like a resister; I am thinking this is wrong.
Now I question the basics and from reading here, I now understand the L100 have a different polarity from the “standard” up until sometime in the 80’s.
BEFOR I REBUILD MY N100 crossovers wrong, I would like to know these things please:
I am using Clarity Caps. They have a black lead and a red lead.
I have the parts express L-pads
I am looking at the L100A/N100 Schematic
The RED binding post connection show the reversed arrows (that I would think means return path and not positive).
This changes to a green wire on the solder strip of the N100 and goes to the RED binding on the 123A (Right?)
The Black Binding Post connection with forward arrows goes through to the Black binding on the 123A (Right?)
Would I still connect RED to RED and Black to Black from speaker to receiver? (I have later model other make speakers as my rears and they are red to red and black to black, it’s those arrows on the schematic have me scratching my head.)
I see that one end of the capacitors goes on the red input side and the other to terminal 3 on the L-pad. May I assume red to red and black to L-pad?
The Black side goes to terminal 1 and onto the LE5-2 Black? And the white from terminal 2 to RED?
For LE 25’s I know they were reversed at the L-pad and had terminals on them that allowed the hook up only one way, but I redid the wires and may have “corrected it”. SO Terminal 1 to Red side to the Male spade into the female socket on the LE25? And Black from terminal 2 to Female connector to the male terminal on the LE25??
I would appreciate someone helping me rearrange my assumptions correctly and my current thinking to proper thinking,
Thanks,
