There are companies that build their own drivers and use simple 1st order networks. There are others that use extremely high quality drive units that use 4th order crossovers. I don't buy into the marketing of B&W.

What it really boils down to is the tradeoffs that are determined in the network order - what parameters are you willing to optimize and others sacrifice.
