Where's 9.1, actually where's 11.1

[Woochifer]

Maybe I just need a dose of reality. I think I'm just obsessed with building my own type of monster system and am not even thinking about movies or music anymore. If that's a proven industry standard, then I should be happy and 5.1 does get me immersed in the movie quite well and can be a releif from a sometimes confusing to the ear 6.1/7.1 set-up.

If a 6.1/"7.1" setup is confusing to the ears, then it's either setup wrong or the room is not appropriate for that kind of setup. If more sounds worse, then it's better to stick with a "less is more" approach.

By the way does anybody know what the movie theatre uses?

I thought I'd already answered that, but here's a short summary of the theatrical formats in use.

1.0 (optical analog: optical mono)
2.0+ (optical analog: Dolby Stereo, misc. matrixed optical stereo formats)
5.1 (digital: Dolby Digital, SDDS, DTS; analog: 70mm magnetic)
5.1+ (Dolby Surround EX)
6.1 (DTS ES)
7.1 (SDDS-8, DTS special format)
