I’ve heard both extensively while choosing. Both great, but for me Legacies were better and essentially more for the money. I was looking for sound cues and in Fleetwood Mac’s "Dreams", during the chorus, the male vocals seemed to come from below on the Endeavors whereas with the Legacies they were placed on a stage behind the speakers. It may just be a position issue obviously but Signatures go down deeper and have a much better mid/hi unit as well. Side by side would have told me exactly what the differences were, but as it is, they are both fantastic.
