When I start looking for it, it isn't there, so maybe I dreamed it all :?~:-?~:???: However, when the system was installed in our church, a Meyer system based around a LX 300, the company acoustician ( [URL="http://www.mediaspro.de/"]Startseite | MediasPro[/URL] ) was talking about a layer of cancellation of the whole room, to which a virtual space was to be overlaid. As the only problem area was some slap-back from under a balcony in the main seating area, I believe they ended up with only providing some cancellation for that part, but the concept as described was to actively reduce early reflections in the entire room. Supposedly there are at least a church in Germany and one in Italy with more advanced systems where the goal from the outset was mainly to reduce the reverberation in cavernous structures, more or less the opposite of our church where the sound just gets reflected upwards between tall parallel brick walls and there is a lack of reverb. The other (cheaper) systems I've heard in a couple of churches and theatres are simply the add reverb type that you describe, where "dry" is "off". I have come to realize that a few installations that was referred to as noise cancelling in their publicised plans (airports, foyers, hallways) are actually noise-masking installs with no active cancellation.
