Need Help With Port Config.

how do u convert a round port into a slot port.... I got this design for an enclosure that's 16.8cu.ft. net w/ (4) 6" round ports 9" long ........how do change (4) rounds ports into an area/slot port ????

thanks,

well (4)6" round ports has 113.04sq" of port area

area = pi*r^2

3.14*3^2=28.26

four ports: 28.26*4=113.04sq" of port area

so to convert that into a square port you just need to come up with some measurements to give you around 113sq"

for example a port that is 20" x 5.5" gives you 110sq" or a port 20"x5.75" gives you 115sq" of port area...which is pretty close to 113sq"

20" x 5.65" =113sq so, is 20" x5.65 the width x height and if so, whats the depth??? is it still 9" deep????

thanks

come on .... anyone ?????

the depth is gonna change b/c the square port isnt gonna displace as much air....so basically your enclosure is gonna end up bigger and ur port is gonna need to be shorter...
