Honestly - It's best to model the circuit in Spice. Most online documents about crossovers and the difference between 8 and 16 ohm drivers are going to talk about the crossovers as if the load were resistive. They may mention a Zobel, which would then make the load impedance act more linearly, like a resistance. But the response curve of the π compensation network is shelved, with rising response at higher frequencies. It does this by using the voice coil reactance as part of the filter. So model the circuit with Spice to determine your values of R1, R2 and C1 when using a 16 ohm driver.
