I am curious about these "things". How do they work? Where do you place them? Are they limited to a certain frequency?
Do they subtract sound? Do they add sound? Do they neutralize sound? Is there a way to measure a room for appropriateness? How do you determine how many you need? If they are all the same size, how could they possibly have such consistent success in such varying systems/rooms?
