TH-18 Flat to 35hz! (Xoc1's design)

[maxolini]

Anyone that has a 3d file of the design (first version)?

i looked in my stash of sub plans and
i found the last iteration of it drawn by Deman, if you want it let me know,
it is a fusion file, and 2 dxf files CNC ready that have all the panels and bracings

and i found the original plans that do not have the cone correction
but is a PDF, see 4th pic from top to bottom.

327 liters is 19,955 cubic inches.
A Chevy small block V8 has 327 cubic inch displacement, 5.36 liters.
The air volume occupied (filled) by the Bianco-18SW450 driver is 7.32 liters, 447 cubic inch.

It would be something if subwoofers could handle the horsepower a car engine can produce..

Correct! I should have stated a 327CID V8.

i guess, cylinders and pistons are metal !, drivers have paper cones , even kevlar ones can't match a V8!!

But, they are BOTH all about bore x stroke and moving air!
