I have decided to use rockford's recommended ported enclosure for my Power HX2 15". The recommended enclosure calls for 4 (4 X 18") round ports. The problem with that is that the box is only 18" in diameter. So, i have decided to go with a slot port that will help with bracing anyways.

I believe that it is tuned to 33hz

The dimensions of the box are: H-20" W-25" D-18"

Box volume: 3.5ft^3 (net)

if i want to use this box, but with a slot port, how could i convert the info i have to get the info that i want (port specs. of a slot port so that i can build me a box)

P.S. this is my first box

and i do understand that the box dimensions will probably change, this is acceptable

oh just tune it to 33 hz with the reccomended enclosure volume. err i thought you made the box already and had the ports in the box.

And resize your sig too, while you're at it...:)

300px /= 225px, last I checked.
