To add to Jerry's info...
The tweeter and mid crossover components are connected to the #1 terminal in the 3a. Also, the 3a is rated as a 4 ohm speaker system.

HI, Matt!

It makes no difference.

There is no "ground" as these are all AC circuits.

Terminal 1 is "common" to the woofer and the the other drivers and it makes no difference which components are wired to the common.

Some speakers have a PLUS or a RED indication and the purpose is to show driver POLARITY. (A positive signal at the RED or PLUS terminal causes the drivers to move out.) This allows us to hook up speaker systems from different manufacturers and maintain phase.

Hope this helps ...

While refurbing a pair os 2a's I found some confusing wiring/polarity issues regarding the crossover network. The wax cap box and the woofer coil are both wired to terminal 1, which I always interpreted as common or ground. Terminal 2 and T, which I always use as the 8 ohm input, are wired directly to the drivers. Why aren't the crossover components wired to the 8 ohm input terminals as they are on the 4x and 3a systems? Does it make any difference?
