Thanks for bringing that up. According to this article, it means both wall and very large cabinet:

I need to make a correction to my discussion with @donvito101 (but just one) based on that article:
I was wrong about sealed always being acoustic suspension. Infinite Baffle designs are sealed and not AS. Definitely a flop! Isobarik enclosures are extremely rare, and technically sealed, but not called "sealed." They are called "isobarik,"
I was not wrong about:
More info on the LS3 here:

Lastly, most 3-way or more speaker systems use AS in the midrange even if the woofer is bass-reflex. There are weird exceptions.
Best,

I was not wrong about:
- In current usage "sealed" is always synonymous with "acoustic suspension" unless otherwise stated.
- The BBC LS3 models however are far too small to be Infinite Baffle and are clearly AS.
- Acoustic suspension is still one of the most popular speaker cabinet technologies in the world.
