LOL - I'm a B&W fan (although not as much as I used to be). Joseph Audio bought out (or uses) Infinite Slope and their crossover ideas. From a 1996 Stereophile:
Joseph Audio is a relatively new New York based company making loudspeakers designed by Richard Modaferri, who for a long time was one of the engineering lights at McIntosh. All the Joseph models feature Modaferri's patented "Infinite Slope" crossover topology, where a modest network (in terms of number of components used) produces high- and low-pass filter slopes in excess of 100dB/octave.
As I understand it, the crossovers have a very severe drop. For example, if the crossover from the midrange to the tweeter is at 5000 Hz, almost nothing below that point reaches the tweeter, and vice versa.
That sounds like a good idea on paper, but I'm sure that accounts to some extent for the shortcomings I perceive.
Let your ears be the judge - pay no attention to the man behind the keyboard.
I had another point to make, but it escapes me.
