From what I've read, it sounds like a marketing word for their bass boost circuit.

Then it sounds like it's something to do with the crossover...

thanks jim yeah thats what it was sounds better too

Its a variable Q subsonic filter circuit. The idea is that by setting the Q of the SSF high you can get both a boost just above the half power point of the SSF and a SSF all in one circuit with one control. Both the freq and the Q are adjustable.
