Crossover settings?!?

[azereus]

I've never really been clear on this so i was wondering if anyone can help me confirm whether or not I have my crossover settings correct on my sub and receiver.

On the sub i turned the dial all the way up to 160.

In the receiver I set the crossover to 100.

So my thinking is that anything less than 100 will be sent to the sub. Because the sub is set at maximum (as recommended in the Yamaha manual), it will accept anything less than 160.

Is that correct or am i way off here?

Thanks
