Very interesting, Socketman.
The part that was a revelation to me was:
more can be done with less by using a well designed driver
If - like Axiom and some other established loudspeaker manufacturers - you design and manufacture your own drivers, perhaps you don't need to put as many components into the crossover. A greater proportion of the overall loudspeaker objective can be accomplished through the driver design rather than through network design, which can result in a simpler signal path.
Conversely, if you have to buy drivers from an OEM, you don't really have much choice but to design the crossovers to fit the drivers in the context of the overall design philosophy.
I've met Dennis Murphy; I think he's absolutely brilliant. And I don't think that the linked article is necessarily at odds with the idea that there is more than one way to achieve similarly good results.
