As a rule of thumb, sharp dips are diffraction artefacts while sharp peaks are
caused by the drivers themselves. Exceptions are room resonances (if the
response is not correctly truncated) and diffractions on repetitive patterns.
The second step is designing the actual crossover filters. All the usual
strategies work. Delaying higher frequency drivers with respect to lower-
frequency ones is a powerful alternative to using asymmetric slopes and yields
substantially improved coherence through the crossover region.
