Okay, I've been playing with the idea of the line array and doing a setup with a few mids and two woofers per cabinet.

Would like some opinions/ideas.

First thought, each towers gets either 3 or 6 of these mids ...

As well as 1 or 2 of these woofers....

As for the high end...

I've got a 12" IDQ that I'd like to try out in the home audio environment, any thoughts ?

Would that many mids be too much ? Would I even need the 10" woofers ?
If i go this setup i would extremely apprecite any help with the crossovers that I can get, still a little nervous about that.

That's not a line array.... that's just alot of speakers.

Yeah I know, i should have been more clear.

one idea was to do a line array with many 3" aura drivers

The other is the idea presented above

Okay your using buyout mids and subs (LOL) and then your going to put a $84 ribbon tweeter in there? WTF? Dude first don't use those subs did you check the specs? An XMAX of 3mm on a 10? That sub is booty. That mid is decent and I would suggest using 4 or 8 of them. As for a tweeter these could work great for a line array: http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=275-035 . Do some research. Several people on the PE board and Madisound board have built line arrays. Drop a few questions and they will be happy to help.

This midwoofer you linked;
http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=299-050

Would work nice in sealed, but in a ported box, maybe four of them in ~1.5 cu. ft.
tuned somewhere from 65hz - 75hz would be pretty good, it has better specs/performance than the 49 cent NSB's I used.

But to make the project really worthy and punish, I'd do a big line array of 12
per tower, either four driver, three chambers or three drivers, four chambers.
You won't need the bigger woofer, instead mate the ported array to a seperate
subwoofer and all is good.

For tweeter, the HI-VI RT2C-A you linked is essentially the same driver in
the small size magnetic planar category, similar to the Dayton PT2B that cost
alot less. Use an array of PT2B and you will certainly destroy some folks.
The $4 dome is good, but you also need a large line to make it an array worthy.

Add a digital crossover and two powerful amps, low impedance wiring,
you should be able to score a system that beats $20k - $40k store bought.

If you skimp on any ingredient, then you take big performance hits.

If you are on a low budget, then make the midwoofer array and stick
a good eminence compression driver w/horn somewhere in the center of
the array aimed at the listening position. This would be a decent solution.

these are the dayton planars your talking about..

http://www.partsexpress.com/pe/pshowdetl.cfm?&DID=7&Partnumber=275-085&CFID=254412&CFTOKEN=72768158

How many per side would suffice ? I dont think I'll be going as high as 12 mids per side for now anyways, this will only be setup in my bedroom in my apartment.

I'd like to go with 6 mids per side, and how many of the planars would you think ?

yes.

They changed the order screen. You should be able to get them for $24 each
in bulk. Ask them for volume discounts.

If you want to realize the power of an array, it's best to make them big, almost close to the floor up
to the ceiling and use it in a normal sized room or bigger. The bedroom isn't ideal unless it's huge. I wouldn't
spend the time and money on a mini-array for a bedroom either. You'd probably get better results by just buying
one quality 6" - 7" midwoofer for $30 instead of $8 buyouts in a small array. The PT2B tweeters or any variant
arn't that good solo or in small arrays. A quality dome costing $50 would be superior. The budget drivers in large
arrays is where they shine because there is power in large numbers, an army.

Look at Jon's modula design here; [posts with the word modula, including the sticky]
http://www.htguide.com/forum/forumdisplay.php4?f=6

Dayton RS drivers, affordable, great bang
for buck, drivers that give bigger names a run for the money. Those are
well engineered and everything is documented including the passive crossover
design which is unique for that design.

There are other kits to choose from from other DIY'ers.
