Ken, it's a bit hard to not interpret it as in part an attack. The circuit pictured isn't technically a crossover and isn't strictly pertinent to the subject. It is however the high-pass filter from the Algonquin(outdoor version of the M3)which was reviewed by Gene with considerable praise as to the sound quality(linked in a previous reply). A "crossover", as the term suggests, both rolls off a low frequency driver above a certain frequency and rolls off a high frequency driver below that frequency. The M3 has never had a crossover, using the capacitors shown to roll off the tweeter(the resistors also visible simply pad down the tweeter to match levels with the typically less sensitive mid-bass driver). The mid-bass then rolls off naturally.

This design has been used for over a decade in the M3 with fine audible results. Suggesting that this is an example of "incompetent" design indicates that the reality of the situation has been ignored for some reason.
