Where did they go? Freespace 51s

Went to look at the Freespace 51 speakers today on the Bose website as I am adding 2 pairs of speakers to my yard and they are nowhere to be found on the website. Where did they go? How can customers order them?

Probably discontinued. Like you, I'm looking to add a bunch more to my Bose systems however, it looks like we need to consider other companies' products.
