Hi - I have a huge room (25x35x20' ceilings) plus open to kitchen and loft etc.  Currently using Meadowlarks which get good volume, have used HDT's in past, but bass suckout was a problem.  I now have an REL sub so its helped out a bit.  I'm wondering if anyone has had experience using any of the Klipsch Heritage series (LaScala, Klipshhorn, Cornwall) or a horn based Altec in a huge room.  My other option would be Zu, but have heard horns would work well in a huge room.  ANy experience to share?
