Dolby recommends 150-135 degree placement for rears. I've always had them about 3 feet appart, but that only got me to the 160 degree or so range. I just now pushed them to 5 ft appart and adjusted MCAAC accordingly.
My question to you guys is do you like your rear speakers closer or pushed out farther? I'm also wondering what changes in AVR output are made when you select the rear channel speaker distance. Does it take a bit of sound usually played in the sides and push it to the rears?
Don't know if this helps or answers anything, but according to THX ULTRA2 processing:
"Whereas THX Surround EX simply called for two more surround speakers at the back of the room for the then new sixth channel, Ultra2 replaced them with a pair of monopole speakers specifically placed right next to each other. Somewhat like the way two-channel stereo can "position" sounds between two speakers, THX with their new process they call ASA, or Advanced Speaker Array
, is able to "position" virtual surround speakers between the side surround speaker and the corresponding rear speaker (it's not really that simple, but it is the best way to visualize it). So while Ultra2 controllers still offer THX Cinema and THX Surround EX modes, THX introduced three new THX modes with Ultra2 which use ASA:"
"Its important to note that the Ultra2 controller has a setting for the distance between the two rear speakers
, the default being <1ft as depicted above, yielding the most spacious sound field. The alternate setting of 1-4 ft can be used to "favor" the music playback mode. By moving the physical rear speakers apart, there is less of a "virtual speaker", with more of the surround sound in Music mode coming from the monopole rear speakers"http://www.hometheaterhifi.com/volum...06-part-4.html
