Crossover setting for 684's

[turnupthemetal]

Any suggestions on where I should set the crossover frequency for when I am listening to music. I am running a pair of 684's with an Athena AS-P4100 sub through a Denon AVR1707. I've toyed with different settings, but am curious what others think and how others have their 684's set up.

80hz though the receiver (speakers on small) because I use a crappy Logitech Z-5500 sub.

It seems to clean up the mid bass, but that could just be a misconception on my part with the subwoofer extending the bass power.

I have the 683s fronts,running 2 300series b&w subs .I have fronts set to 60hz and sub at 80 .Just personal prefrence.I prefere a lot of bass as I listen to reggie often.Whatever sounds best to you is where you should set it.
