just some history for those interested, i got the driver off a friend for $100AU, that's approx $60US with a free enclosure. It's only a sealed though and was made way too small in order to fit into his car 
he had a 1200watt amp running it and needless to say it pumped very hard. However they perform better in ported enclosures which is why i'm building this. He will also sell me a 2nd one for the same price that he has had sitting in a box for a few years. btw how much are these kilomax subs and is there a distrobuter in australia and could someone pls give me a link so i can compare.
once again thanks for the input everyone.
with the ports i might go round then since they look cooler 🙂

Personally I'd consider sandwiched sand filled walls for such a monstrous enclosure. I used it for my car sub using a single 12" driver, but i never considered the effects of having an 80Kg enclosure in the boot of my car. So now it's a coffee table 😉
I'm sure that your one will be bigger and heavier than this, but it may be the way to go...
Inspired from Stig Erik Tangen's Almighty Subwoofer
If you've got that luxury, then take advantage of it. Remember that once you add wall thickness, the large amount of internal bracing required, shelf port etc. into account, it will be a fair bit bigger.
Vikash: my jbl2226h is similar to the 'Almighty Subwoofer',but it more sanely tuned to 33hz not 24hz,more SPL ,its Fs=40hz afterall!.leave the low tuning to the speakers that are designed for it
your lucky to get such a cheap deal!,can u sell it to me for cheap too? LOL
the bigger they are the more bracing they need,
and the bigger the speaker ,the more SPL you mite have..
and the more SPL,the more cabinet vibration
-i guess😉
2245s are about 800$ or 1500$ new arent they?
id go shelf port,i dont trust weak little pvc pipes with HIGH spl when they are long 
yeah the actual shelf port itself will take up volume..
use 25mm mdf
200kg monster😛

I always like to consider room gain when i'm doing a sub. Designed flat to 20 Hz or even 35 Hz these things will have a rise when you put it into a room ... often the rise might be more considered a big lump. With this in mid i usually don't consider f3 but f10. I like to see a curve that starts slowly rolling off somewhere in the vicinity of where you start getting room gain.

hey man,have you thought of a basshorn??
with 900L you could have 30hz i estimate.
my basshorn im thinkn of is about 550L and its F3 36hz or so
if your interested just say.
it definately is the hardest to do,but pays off the best :-D

Thats a PA driver - any of those arent siuted for home use - their bass is I would say unpleasant - too fast and way too punchy, believe me, thats for DJ use. This baby is worth ~500, just sell it, buy smht 15" with big excursion and low fs.
PS 900l enclosure is overkill, sure it can give you 110-120db at 20 hz but in a less than 50-70 sq.m. room you'll have the feeling that you ear drums are popping out... I'm a DJ I know how they sound in small room.

Hi Vec7or,
The JBL 2245H can be used as a PA driver, but it's primary use is in premium studio monitors. While the driver and the big box might be a little bit over kill for a small room, it will indeed be a very good sounding sub-bass for music as that is what it is designed for.

Agreed, but IMO I wouldnt go for PA drivers at home...
They are made for high SPL, sure they'll do great for home cinema - you'll get that cinema like bass - fast, stong, well you now the feeling 😀
