The speaker, depending on the version, is built without chokes in the crossover, only caps, and none of them are shunts.
So what happens is in the low frequencies the speaker is about 19 ohms. Then the mid horn rolls in and since the bass horn is not rolled out, the two are in parallel, so the impedance drops to about 8 ohms. When the tweeter rolls in, neither the bass or mid is rolled out, so they are in parallel with the tweeter.
This is why so many owners of this speaker have really had to dig to find a tube amp that will play the speaker properly. The reason the speaker is built this way is that the designer used a transistor amplifier.
