The average Sd of a 6.5" cone is around 150cm sq, the average of a 12" is around 500cm sq, so that might throw off the frequency response a bit. Will be interesting to see it measured, nice work.

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?

Btw, that same 6.5" sub that is now $125 at partsexpress, was on sale for $35 just a couple months ago. Crazy how prices have gone so wonky there lately.

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,

for about 0.002 seconds

Cool build and welcome. Feels good to inspire others

What do you think it
sounds like? I mean you made your own horn since the drivers and expansion
are different. Was the folding easy to build?
