ABSTRACT
A first-order crossover has the great advantage that it is the only type that can produce linear-phase and minimum-phase response and a flat amplitude response. As a consequence, it is the only type that allows a waveform to be reconstructed when an HF and LF path are added together. It is potentially attractive for passive crossovers as it is the simplest crossover and so requires the smallest number of expensive crossover components and has the lowest power losses.
