You may find the π Crossover document helpful. It shows various network types, and describes the behaviour of each component in the circuit.
Like anything else, there are many ways to accomplish things, and some things work better than others. Resistors are neither "friend" nor "foe" - They're just part of a circuit. Loudspeakers are partially resistive and partially reactive, so sometimes a circuit is ill-formed without resistance.
Some circuits benefit from values of resistance in series and/or shunt, others don't. It depends on your specific configuration more than anything else.
