As far as I know the orginal Legacy had a rectangular plate for the tweeter orientated sideways with the name Advent written to the side of the tweeter. Legacy II's had a rectangular plate orientated vertically with Advent written below the tweeter. Advent III speakers are taller and have a square plate without any marking.
All 3 used a 10-inch woofer.
Try this (I asked it .. but it needed a search for me to remember asking the question!):

MMM, looks like a Legacy 2, however that is not the correct woofer.. Should have a "regular" not inverted dustcap, and one that is semi "breathable", also the woofer cone should have "rings" in it. Looks like someone may have "upgraded"
Looks like a well built woofFrom what I remember, very similar magnet size and structure to the "orginal" Legacy unit. I am betting they sound quite good. How is the deep bass response on them?
WOW! that was the answer, I tried a search with several different combos and found a lot of info but not that one.
