TIME OFFSET AND CROSSOVER DESIGN.

This paper examines some aspects of crossover design to correct for the time offset due to acoustic center displacement in coaxial transducers. The effect of this time delay on the magnitude response of first, second and third order crossover networks is examined relative to the vector sum of the network outputs. Various transfer function approximations to spatially related time delay are examined. Finally, the magnitude of response of crossovers employing time delay approximation networks are considered.
