2025 prove me wrong

a=lw

it is proven that the square is %25 bigger then a round subwoofer. and a round 15 cone area is 176 square inches. do the math sir.

you can count a 3rd of the surround towards cone area.

ok let me teach you basic math since i guess u skipped that class

area of a circe is radius x radius x pie

area of a square is length x width

so lets do an expirement

circle 15 in sub- 7.5x7.5(3.14)= 176.625

square 15 in sub- 15x15=225

edit- guess what we get when we take 225 and multiply it by 9? 2025 **** i guess i was right
