Hi Jake, glad to hear you got a new receiver, I did too. The THX standard is 80Hz, but I have experimented with 60 and it doesn't sound too bad. Depends on your room/size, plus do you like it LOUD or comfortable. One thing to keep in mind is with a 80Hz x-over point, your receiver doesn't have to work as hard as with a 60 Hz point, how much difference I don't know but I have noticed my old Yamaha would get a little warmer when using the 60Hz point.
