why are the 2 drivers mounted like this? why not both on one side?
An externally hosted image should be here but it was not working when we last tested it.

Both cones move at the same time in the same direction. So one of the drivers needs to be wired out of fase.

Tang Band W6-1139SI 6-1/2" Subwoofer
i picked the subs up REALLY cheap,
a little finish sanding/work and this will be the subwoofer for my new boom box build

yes it sounds great,
not ive tested nothing.
the only math i did was *guess* that the cone area of a 6.5 is slightly less then half that of a 12.
so i divided all the numbers on the plans by 100 and multiplied that number by 42 (42%??)
my thinking is if the proportion of cone area to box physics is the same, i should get similar performance
it definitely gets very low and is smooth in its delivery
thank you Petter Persson for the design

i arrived at my box calculations with some very basic math
seems i was wrong though because it seems a 6.5 is closer to 1/3 not 1/2 the cone area of a 12?
ive scaled many designs like this over the years, find a box design i like, find a driver/s i want to use, and built something i believe might work.
ive had good results so far, i never measure anything and always get lots of bass and never built anything i didnt enjoy using.

So, you didn't use the push/pull of the original design?
I couldnt get the driver in backwards, the magnet is quite deep and the space available (in my box) quite shallow,
i thought about spacers,
