I decided to start another subwoofer thread. Here are my questions:

If I set my fronts to “small’ on my Denon AVR, the crossover is set to 80 Hz. So, frequencies below 80Hz are sent to the sub.

If I set my fronts to “large” on my Denon AVR, the fronts handle the low frequencies. But how low? What is the new crossover? I’ve been looking through the Denon manual, but can’t find the answer.

How does the sub's crossover switch work? Let’s say I enable it and set the crossover to 60Hz, do all low frequencies get sent to the sub and the crossover setting acts like a “sub traffic cop” and only allows frequencies below 60Hz to be produced?

Another way to look it would be, if I set the fronts to small, the crossover is 80Hz. If I also enable the sub’s crossover and set it at 60Hz, what happens to the frequencies between 60 and 80 Hz? Are they not played?

Does this make sense or am I out in left field?

Thanks
