alright, so here's my gear set up: 2 yamaha hm80s, 2 rokit g2 5 inchers (bought cheap, otherwise i'd never buy em), tc electronics impact twin and an imac something or another.
how would one set up a 5.1 with this set up, and what else would one need.
i'm also looking into the blue sky 5.1 desk monitoring system, just as an interesting thing, butttt as it costs as much as the dynaudio bm6a acoustics i want, it's a toss up.
thoughts? ideas? advices??

Can you tell us why you want a 5.1 setup.
The only reason I ask, predominantly, mixing for 5.1 is reserved for film and very rare musical events, special DVD music releases.. it's not exactly a mainstream audio format and if you were going down the film route, your mixes would be expected to be perfect - audiophile grade recordings and mixdowns.
Cheap doesn't really cut it if you're trying to mix to 5.1. Plus, the .1 (sub or LF fx channel in film) is going to require a heap of acoustic treatment - which, to be honest, you should have anyway if you're mixing with lots of speakers on the room!
Either buy 4 x Adam A7, or similar excellent price/performance monitors.. or, if that's still too expensive.. I'd suggest, perhaps, finding a speaker (not necessarily a studio monitor) you really like the sound of, and buying sets of those. (B&W, Infinity, Polk, Wharfdale, Tannoy etc.)

it seems i should have done some more reading before i posted this.
i'm not only interested in surround sound mixing, i would also like to build a surround sound PA system for our little scene down in the southeast.
i've also found that, as tomos said, this is not a cheap idea.
i was under the impression that 5.1 was about as complex as it got, but i was wrong
(reference: http://www.highdefforum.com/speakers-surround-sound/10361-discussion-surround-sound-systems.html)
in the interest of the community, i'll be posting everything i can find about this stuff, and if anyone has anything to add, i'd be grateful.
my question at the moment: for surround sound reinforcement, what do you need to "split" the channels up? |

<Ahem.> I'll just leave this here.

Actually, this is nothing. I've know there are 100+ speaker set ups so you are completely "surrounded" by the sound. No single point sources, it's as smoothly surround as you can get.
Blame the Japanese..

I heard them at SAE London studios and I couldn't believe they sell them as 'monitors'. To my ears it sounded like a tweeter on a stick with a sub that sounds totally out of place because the hole in the middle frequencies you could drive a truck through.

read about wave field synthesis, its pretty streight forward as well..
Also check surroundsound recommendations after ITU-R BS.775-2
wich suggest for example a 40qm room and i think 70% angle of the speakers..this is for studio setup..outdoor is even more complex with running time differences and correlation and all that stuff. the most expensive stuff will be the measurment and generell setup of speakers etc..but its just pure bliss if done right..and when people are able to drive multichannel livesets like Space Tribe or GMS/Zorba..
good luck 
even the CUBE of the IEM must be awesome!!

ya'll rock.
i've gathered the PA gear to do a 4 point "surround" system.
tests and theories shall come as i find a venue willing to let me experiment.

then its quadraphonic or over cross stereo..wich gives you better control over phase issues and might be not a bad idea for a venue..

Quadraphonic actually really suxx in my opinion, I also call it the cancellation device no. 1, and it really is.
If you want to go surround, 5.1 or up is really the way to go. do not save money on that one speaker for your PA, it will make a big difference.
Why does he want 5.1 Tomos?
Because he is going with the times, not like most people here...
so your question really seems to be, 5.1 or dynaudio bm6 and that is indeed a difficult one.
Generally speaking put the cheapest speakers in the back, the 3 good ones at front.

he talks about venue speakers..and its way more difficult to set a proper 5.1 setup without phasecancellation as a 4.0 setup wich is actualy easier to setup in a venue (PA)..
for Studio purpose i would suggest 5.1 as well..
Delay settings depend on the distance and actualy even on climate stuff.
To calculate the delay time you theoretically take
sonicspeed = c = 343 m/s at 20°C
time in ms = t
distance in meter = d
t = d/c
43,73ms. = 15 meter / 343 m/s
for example..
this is simple delay tower calculation for festivals or concert halls..
how it is calculated exactly with quadraphonic or 5.1 when speakers are build in a circle i actualy do not really know.
you might need to seperate frequencys anyway for rear and bass etc and might need a measurment software and a mic then use impulse responces to find the crossoverfrequencys and the phase behaviour.
good luck

but in the end if you just do it the first time you might use a track with a very clean bassline lowpass it down to 500HZ and adjust the delaytime by ear...until it sounds tight..should work as well

why for a studio and not for a venue?
In my book quadra or kacko phonic always seems to produce more phase cancellation issues. And 5.1 sounds so much more real too.
It is also of importance of the layout of the venue, is it indoors, outdoors? What shape does the room have?
5.1 capable parties, I am still waiting for this one to happen, and you're right, it is expensive, but oh so exquisite when done right !!!
the cutoff between lfe and 5.1 field is often put at around 120hz with a 2 pole filter, I suggest to get bass management.
