They are passive and displace air with various forms of reactive mass.
but they are not passive radiators. By your new re-definition everything can be considered a Passive Device. But I'm ahead of you. The Red X Coordinate Pen, the reason I keep mentioning it, actually demonstrates that it is the *words* and other *information* contained in media that affect us. Thus, when you remove books, cassettes, newspapers, telephone books, etc. from the room and the sound improves it is not because the objects are passive radiators or even passive devices, it's because the words and data are the problem. it's why I used the word INFORMATION earlier. If you see what I mean.
You probably aren't familiar with the Japanese fellow who found that placing calming message in water result in beautiful well-formed crystals when the water is frozen but that messages that are negative such as I hate you result in ugly ill-formed crystals. I thought everyone heard about that. It's all over YouTube.
