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?

..."Go to Dolby's web site, and they explain the various set-ups for 5.1, 6.1, 7.1, and PLII.

This is not bad starting advice, as a good point of reference and suggestions. However, to be true, each setup/room is different, and there's A LOT OF VARIABLES TO CONSIDER! If you don't know what you're doing, you'll be getting hodge-podge sound from all your speakers. Placment is a balance of getting a properly scaled soundtage perspective, and simultaneously getting basically "flat frequency response"(and even response) from all the speakers! Anything else will give you lackluster performance for certain!(what everyone ends up with doing it themes, themselves sadly..I know Basically, as I've been doing this for years for a living)
All the other variables will then need to be considered, like proper toe-in, "aim", and acoustics considerations.
Basically, you're better off(especially since you spent all that money on gear) haveing someone consult you for best. Otherwise, spend years learning and studying, tinkering and tweaking. Bottom line, much more info is needed to recommend for ANY ROOM/SETUP!
Telling someone to stick your speakers at such and such a distance or location in your room is all relative. Also, each speaker is different, and reacts differently in the room. It all must be considered, as the room/setup/acoustics/tweeking/etc, all add up to easily 2/3's of the performance...no joke!
You spent hard on the gear...I suggest considering spending even wiser on the more critical setup/acoustics proceduress if you want anything remotely resembling world class sound!
Yes, equip makers would love you to think that simply buying gear is the answer to world class sound...seasoned audio experts know different. And you'd be amazed at how many (guy's especially) people think they can buy some fancy gear, stick it in a room, and think they have the best sound!...they're wrong....most end up with poor sound, I garantee it, sadly.
As for your gear choices, your gear is fine. You could alwasy tinker with power sources and wires and such. But otherwise that's good stuff. However, like most, the speakers really should be chosen first, as they're the most important in the gear. You then should match gear to match! That's correct normally. But, it's all workable if need be. Good luck
Basically, it is needed to know your room dimmensions, layout, basic acoustical properties, and all the variables in the room, seating locations, etc. All this will make it easier to point out speaker options really.
These are mostly music speakers I might ad. Which is fine for some applications, but not a big space like you're using! May I suggest some more high end "active", higher efficiency focused designs better suited to your HT applicastions?
I've sold WATT Puppies and B&W's over the years, and have some experience with Dynaudio. There are simply better MORE EFFECTIVE choices for what you're doing IMO.
You might consider some "ACTIVE" speakers from a company called AVLAR located in Southern CAlifornia. They''re very high end sounding speakers, that are much more dynamic, focused and powerful sounding than the more passive speakers you're mentioning above. They dynamic realism and pressence will be much more cinema like, and yet still remain "audiophile" grade in refinement!...just a suggestion.
The traditional Stereo speakers you're looking at won't DELIVER THE GOODS for a high impact HT. I know this from 20 years and 6 high end audio stores worth of working experience...not to mention I do custom thaters myself, and am a consumate audiophile tweak myself.
Anyway, it's all good...it's just that some choices are much better and effective for your task.
Anyway, good luck-----------------------------------------
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
