Port help on box design for ext cab truck
Hey guys, I have finaly decided that I would build my self a ported box for my Arsenal 10 and get rid of the prefab sealed box. I basicly will be useing the old box as a guide to get the right dimensions to fit under the seat and will be extending it out further for the extra room for volume and the port .
Going off of old AA specs, I need 1.2cuft volume after all displacement and tuned to 35hz.
I basicly came up with 18"W x 22"D x 6.5"H1 x 9"H2 --- This is the actual box and does not include the 'doglegs' that will keep the downfireing sub off the ground.
Useing 3/4 mdf this should give me 1.22cuft +/- . I plan on putting the port in side ways ( width wise = 18inchs) so I have some room for depth. I will be useing a round port.
Useing a calculator online, it says a 3inch port 10.76 in long will be 35hz in a 1.2 box. Is this correct?
Does this sound right for the port?
Thanks guys for the help, I am looking forward to getting that Arsenal ported.
Edited to add:
Just put in a order from Partsexpress for a 3in port kit and a terminal. Going to go to the local hardware store and pick up a sheet of 3/4MDF for $15.
