Crossover Settings?

[JckToWN10]

Hello, Hope all is well. I have a question about the crossover settings on my system. Here is what i have; BOSE 201 V (fronts), VCS-10 (center), and Bose double cubes for rear surround. My receiver is Yamaha RX-V663 and my woofer is Yamaha YST-315 . Here's the thing; I used the little microphone to set my speakers and it set my crossover in the receiver to 200Hz. Is this good? How should i set my crossover on the subwoofer and in the receiver? My subwoofer can be set up to 140Hz. The receiver goes up to 200Hz. Thanks in advance
