Hi -

Will be running Aon3's for L/R and an SS50C center - SS3s for surrounds.

How to best wire the FF4?

Use LFE or speaker connection (or both) to the 50?

Thoughts?

Thanks

You'll want to use the LFE/Sub-in connected to the subwoofer output of your receiver. I would suggest a 120Hz crossover for the SuperSats, 80 Hz for the Aons (all selected as "Small" with Subwoofer "Yes"). This will be the best configuration for overall performance.
