Recently the use of in-phase crossover networks has been recommended to eliminate polar response asymmetries (lobing errors) in the crossover region of multiway loudspeaker systems with noncoincident drivers. In this paper a simple geometric arrangements of three drivers in a two-way loudspeaker is shown to eliminate lobing error independent of interdriver phase relationships, thereby removing this error from consideration in crossover selection. The suggested arrangements eliminates off-axis nulls and provides another polar response when the drivers are not driven in phase.
