I picked up a few 044 tweeters for spares. There's no orientation on them or any markings for +/- on the connects. There's a male and a female lug on them. Does anyone know which lug is + and which is -?

There's a "+" mark on the front housing/casting under and a bit to the side
of the male terminal, if that means anything. If hooking up to stock wiring
(e.g., L96/112/150A) I'd be hooking up the mating connections...

I see that now, thanks. I was just assuming that when the day comes I need one, I might not have the original M/F wires.

Thanks, already have those for the whole L line. The L96 and L112 use the same XO, and they all use the same wiring scheme.

... which is interesting, in that I would interpret the schematic connector
symbol to be a male connector on the wiring harness (yellow/no-stripe
wire) going to the "+" terminal on the HF driver.

The other interesting point (to me), and part of why I tried to keep it brief
in my earlier post, is that when disassembling a dead 044, I seem to recall
the "+" marking on the dome kit/board being the female terminal. Maybe
Gordon can verify this when he get's the one I sent. The board the dome
is attached to is keyed, so you can't reverse it (without putting the dome
down on its face :p)... this would contradict the mark on the casting, but
agree with the schematic.

Reader's Digest version? Replacing a unit and using the stock wiring,
you're probably fine. Using an 044 in different or DIY system? You better
be prepared to figure out driver phasing yourself.
