Subwoofer Crossover Question

[Tall Dog]

I have a Yamaha RX-V3800 receiver and a Velodyne VX-10 Subwoofer.

I have a question about running the receivers YPAO setup program for the speakers.

The subwoofer manual says that when you run the Receiver mic program, to set the sub's volume at about 1/4. Other than that, it says to follow the receiver's directions.

The receivers directions say to set the sub's crossover frequency to "max", which for the Velodyne is 200mhz.

So, I run the setup program. When the receiver is done, and I look at the settings, it has the receivers crossover set to 200mhz(which is what I set the receiver to before running the test).

When I watch a movie, everything sounds pretty good to my untrained ear. My question is, most of you guys say the sub's crossover frequency should be 80 mhz usually.

Should I change the sub's crossover frequency to 80mhz, or is my receiver handling things internally to provide the best crossover?

Thanks
