Default dual 15" Reflex Sub help

Guys,
i was going to get a pair of these
http://www.fullcompass.com/common/fi...ty%20specs.pdf

at a pawn shop but they wanted 400 for the pair
and since the drivers seems to be in very bad condition i decided to build my own
ported boxed cabinets

what do you suggest, i prefer non trapezoidal as is it harder to do the cuts on the plywood, a rectangular box will be better
any pointers ?

i plan to furnish the box with neodymium drivers
and use 1/2 plywood with internal bracing
to make the box not too heavy
3015LF or 15NDL76 to say some in paralleled to get 4 ohms per cab

Thanks

What amp will you use?
What type of music?
What size of box.

The FatalPro 18" neo is not much more expensive.

If you are going to dual reflex -- think PPSL.

Music is ballad/pop with 2 live singers, keyboards and drum machines
live electric bass sometimes, but mostly 2 singers with arranger keyboard and drum machines

the size of the box , i like the size of that dual 15 from community
so i prefer a dual 15 than a dual 18 ,,, too large
mostly indoor venues
i have 2 peavey pr12 and with the mid highs spl's i am ok
but i lack the low end ompth so thats why i am looking to make a sub
i have a crown XLS drivecore 2000
and dbx driverack PA... at last... Sigh!

DJK's designs in the two links are good.
If you are going to use 1/2", use a lot of bracing.
