Hi everyone.  I have been experimenting with the beosound theatre connected to external speakers.  What I have set up now is the theatre with 2 beolab 8000 as front left, right and 2 beolab 17 as surround left right.  Then I got a beoamp 2 connected to 2 external speakers for the atmos.  I finally got everything calibrated the way I like.  Now I wanted to conduct an experiment- but before I do just wanted thoughts and experience. What I intend to try is assign the 2 external speakers on the ceiling as the front heights and the 2 internal up firing on the beosound theatre as the rear heights.  Logic tells me this is not a great idea, but research on how atmos works tells me to give it a try. I would appreciate any thoughts on this.  Thanks in advance.
