First off many of the Canadian speakers are designed in the national reaseach councils anicocic chamber. Every one of them sounds terrible because people don't listen to them in the same anicocic chamber in there home. But if someone aspires to build there room into that no problem you might want to try out a cheap Canadian speaker in your room when you get done. Perhaps they will sound ok in your room.
That being said I do know one fellow who has an anicocic chamber in his house but that is not his listening room that is for measurements of speakers. He is a writer for an offshore hifi magazine.
