I think gunbir said it best.
B&T corssover slopes for home speakers are primarily a funciton of the driver's parameters becuase the relative positions are quite standard such as W-M-T or M-T-M etc... in fact Joe D'Appolito's work shows that in a M-T-M config certain crossover topologies are favourable over others.
In a car enviroment the relative position of drivers can also mean that certain slopes are preferable. For example if the drivers are very far apart and if the sloeps are steep you might be able to distinguish the various drivers when in reality you dont want to (all 3-4 drivers should sound seemless).
I do not prefer steep slopes close together of reasons that reactive passive components interact with each other's electrical characteristics (dependant on frequency). Laplace Mathematics will make this clearer but I think if we delve into that here we might have a revolt. 4th order slopes 1 decade apart are fine but 2 octaves apart have audible after effects. |
