The network is correct. It's a voltage divider that is bypassed with inductance to give some boost at the low end. This compensates for the difference in efficiency between horn loaded and reflex loaded regions.
There is a misprint in the tweeter section though. Coil L1 is mistakenly labeled 1.0uF when it should be 1.0mH.
