What are the speaker placements for 7.1 HT setup?


Dear list,

First and foremost, a great thanks in advance for all
helps in all forms.

I'm in the process of setting up a separate multi channel
audio system for HT. I have acquired the following
equipment for the purpose that fits my budget and taste.

1) Sony DVP-NS999ES DVD player.
2) Mcintosh MX134 pre-amp/processor
3) 3 MC1201 monoblocks.
4) 2 MC602 stereo amp.
5) Monster THX 1000 cables.

I haven't committed any plunder I hope?

I'm in the process of speaker selection for above setup.
Now, the MX134 is capable of 7.1 surround processing, how
many center speakers do I need? What are the correct speaker
placements for 7.1? Do I have a rear center? Is 7.1 better
than 6.1, why?

I'm with Hbarrel...maybe we could just camp out in the yard or volunteer to run errands for kee tan....Interesting comments from Flrnlamb about speakers...Avlar? hmmmmm
Well I'd be interested to see where you end up putting your speakers, and with which speaker choices you end up with. If you use dirrect radiating speakers all around, localization and distaction from the rears is going to be hard to get away from! If it's not done correctly, you WILL BE continually distracted and "pulled out of the movie" from to much dirrectionality from the rears. This is a common problem with dirrect speakers in back/sides. It's like someone talking non-stop in your ear while you're watching a movie...very tiring, real quick! It's an artform indeed to find the place they sound best in the room, and or end up "EQ'ing" them, plus "making them dissapear properly for the effect.(I know lots of audiophiles think monitors in the rears is more "specific sounding", but this is not how movies were mixed back there, I'm sorry. (it can be done for compromise if careful however).
Another issue for you will be how your speakers sound during your "test spin" with them. I mean, they'll sound INFINITELY DIFFERENT when not placed properly, and with little or no acoustical considerations/treatment in place. Or has this all been done?
good luck
If you look in the back of your MX134 manual, it shows you how to do the the speaker placement.
