Axiom Home Page Forums General Discussion Home Theater subwoofer setting

Hi all. I'm trying to setup my home theater system and I'm getting a bit confused about how to setup the sub. I want my Yamaha 1400 receiver to be responsible for the frequency cut off to the sub. The problem I'm trying to get around is where to put the frequency cut off on the sub. In the documentation it says to turn the frequency on the sub to maximum. Does that mean to turn it to the highest frequency (150 Hz) or to the lowest frequency (25 Hz)? I'm thinking it means to tune it to the highest value (150 Hz) to allow all the fequencies that the receiver is sending. Is that correct?
