Sorry Bob, but I think you're missing the point as you're getting too hung up on semantics rather than the design purpose. The point is that subsonic filters are designed to suppress low frequencies that are not audible to the human ear, and are not concerned with the speed of the sound waves, despite the arguably semantically incorrect nomenclature. So if you want to be the Thesaurus police (and as I explained in my previous post, an argument can be made you're wrong about that too), go ahead, but the Marakenetz's point is correct.
Btw, KAB does use the word "subsonic" when describing the filter. I took a quick look and saw the reference at least thrice on their website.
