My Wilson Benesch speakers have the same feature. Tri-wire binding posts on the bottom of the speaker. I have to lift each 125 pound speaker and lay it on its side (on pillows) to access the posts.
When I first got the speakers, I thought the feature was cool but after making many speaker cable changes, I find the feature tremendously annoying.
