I'm considering both options - have not heard either. My use for either speaker(s) would be for streaming MOG etc.attached to my laptop or smartphone and for using outside on the deck attached to my smartphone. I would gather that the Audioengine's would provide the best sound and the foxL would be the more portable option (along with the speakerphone capability). Still, it would be nice to hear from those who made a similar decision or who have heard either possibility. Thanks!
