BTW, Mitch, the whole di/bi pole thing was originally developed by Lucus for his THX bogus way of doing home theather. Dolby never had anything to do with it. It was Lucus' way of dispersing sound at home in a way a mulit-speaker set-up at the movie theater. With the advent of 6.1 and 7.1 systems, it's not really needed since there so many speakers anyway. Besides, then THX was first done there 5.1 or Dolby Digital was alreday in in theatres not THX approved. With the Axioms you won't have to worry with di or bi is needed for a rear or side application since one is for a more direct sound and the other a more dispersed. I think the problem with Lucus ans with his THX system is it is what HE WANTS us to hear, not the film's producer/director. If a film is mixed with direct firing side and rear sound then it sould be heard that way. If it's meant to be a more dispersed sound effect, then the mixers with mix it that way. With 5.1, 6.1 and 7.1 avaialble for set-up at home the need for a speaker that does more than is required by the producer/director, mixer is now a thing of the past. The technology is such it has out dated what was thought needed to recreate the movie theater experience. The Axioms do what other brands have tried and failed. They may all work good enough - but when comared, the difference is simply clear
