1) CONJUGATE

0---+-----driver----+---0
    |               |
    +---L---R---C---+

2) NOTCH FILTER

    +---L---+
    |       |
0---+---R---+-----driver----0
    |       |
    +---C---+

I usually refer to them both as notch filters. I just stipulate that #1 is for a voltage-source & #2 is for a current-source. But then again, I can't keep the parallel & series XO straight either. I think it's:

1) PARALLEL

    +---C---tweeter---+
    |                 |
0---+                 +---0
    |                 |
    +---L---woofer----+

2) SERIES

0--+--tweeter--+--woofer--+--0
   |           |          |
   +-----L-----+-----C----+

I just stipulate that once again #1 is for a voltage-source & #2 is for a current-source.
