IF you read ALL the blurb about the Model 12, it says it's an Out Door device..... there was talk by Mr. Parham of horns to go atop the 12.
SCARY STUFF!!!!

do you have the links to those things and the talk

yeah the pi12 is scary
4 of those can shake the ground i think or can simulate a earthquake
i saw the flatpacks are at 900 bucks if my memory dont fail me

What is your intended use (music or HT, indoor or outdoor)?
price range?
needed SPL (realistically)+(100db is louder than people think)?
lowest usable frequency?
How big is your room?
What speakers will these support?
What crossover point are you going to use?
do you have room for more than one sub?

maxo, all the info is on the Pi forum...... though it does take some digging to find, some of it is linked in the Pi paper you linked in your OP........
Mr. Parham is a decent guy, if you cant find the info, post a thread asking for such and he'll respond with enough info to keep you reading for an hour or two.
$900 for a flat pack seems reasonable to me, they are cnc'd to ensure accuracy - there's pictures of a build iirc.
I also seem to remember that the design is tightly designed for his modified driver, I forget the price.
Not a 'budget' build by a long shot.

thanks for the info man

well, as i asked on my 1st post i just want to know what you guys think of those designs because look hybrid also they use coil COOLING that i have never saw before but read on the pi site and saw that they tested 2 cabs
one with cooling and the other no cooling
on real world outdoor scenario
the one with no cooling overheats and died

personally i need something budget and small
i posted the info on my post above

You SPL requirement is pretty tame.
What genre of music is this to cover?
You plan on using this with the SS15 subs?

[djn]

Are these going to be portable or fixed installations? What are the SS15?

If they are in one end of a 100' long room, getting 100db at the other end will require more than 100db at the sub.....but I don't know how much more.

200 bucks is not a lot to spend but if you have the amps and Rackdrive already and can build the cabs yourself, you can make it work for 200.

I would look at a folded Tapped sub. The Pi12 is way out of your price range if you need to buy their flat pack.

How big a box can you transport?

duo or trio band

keyboards , drum machine, bass
3 vocals
soft ballad and instrumental generes

but also when not on lounges or restaurants i get home gigs
when i will need to play pre recorded music
house, tecno, trance, and some dubstep
so i dont want to get a wimpy sub that cant take more abuse
