18xxx

[xpl0it 10+ year member]

i'm designing my box and it's around 7 cubes or more after displacement. it's 20" deep, 22" tall, and 40" wide. I'm going to try and use aeroports but since I'm tuning it to 30hz for my 18XXX, if i try 6 4" aeroports, it says they need to be 382 inches long orwhatever! wtf! What's ideal vent area for an 18XXX and please, how to i get this by avoiding obnoxious port lenths. I did have a normal port tha twas 50 inches deep and 108" vent area.

Well with 6 4" ports you need a total of 176 inch of port length for 30Hz in 7 cube, so thats about 29 inches for each port.
