07mazda3s Posted April 2, 2007 Report Share Posted April 2, 2007 They are gonna sound way different, both loud, but the 18s would sound way lower. Power Acoustik fubar 12 sony xploding amp 2 ft^3 box @ 35hz Link to comment Share on other sites More sharing options...
jcm1689 Posted April 2, 2007 Report Share Posted April 2, 2007 I could be wrong but when i added the numbers up the 2 18's have more cone surface area (508 square inches) over the twelves(452 square inches) but i would go with the 4 12's. they are pushing twice as much power as just 2 18' btls so even thought they have less surface area they are pushing out way more power R.I.P.

Ray Posted April 2, 2007 Report Share Posted April 2, 2007 I could be wrong but when i added the numbers up the 2 18's have more cone surface area (508 square inches) over the twelves(452 square inches) but i would go with the 4 12's. they are pushing twice as much power as just 2 18' btls so even thought they have less surface area they are pushing out way more power The 12's have roughly 12 cubic liters of displacement and the 18's will have roughly 15 cubic liters of displacement. On paper the 18's are considerably louder. and will need less power to do so. As far as the rest of these comments.........

Do 18's not sound lower than 12's bc of the lower fs? Power Acoustik fubar 12 sony xploding amp 2 ft^3 box @ 35hz Link to comment Share on other sites More sharing options...

Slinky Posted April 3, 2007 Report Share Posted April 3, 2007 get the 18s. youll spend less money in the long run and still be just as loud.
