First, it's in this forum somewhere that the LFE signal is low passed at 120 Hz to the sub.

Second, Joel- How did you test to come to the conclusion that you did? Not too long after the 950 came out, Outlaw indeed stated that the crossover worked as it's supposed to: for each speaker (group), the info above the crossover setting for that group is sent to the speaker itself, and below, to the sub. Not a global low pass.
