Should I go sealed or ported?

2.5in wide and 55in long
I think 31sq in of port should be plenty for a 2cf box.

i hope u mean 5.5 in long

ya. and not hav to worry bout the f'in box design

There is that as well //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Ported will definitely get you louder - just depends on how you like to listen to your music. I like the more natural sound of sealed, but if you like it boomy ported is definitely the way to go. I've heard a lot of clean sounding ported subs as well, but that has definitely not been the norm based on my experience.

Nope. 55.25in long.

But oh wow, thats all wrong Because RE calc is dumb..

Sorry nvm scratch that. Instead of making a "maze" of port walls, it just sent it straight through the side of the box, so everything is off...

Sorry.

i'm not sure you need 55 inches, but 5.5 is laughable. mine is 2.2 with 2 4 inch round ports around 21 inches long. it's a little bit of a challenge to design the box and keep the ports inside, but doable.

It's a total pain in the *** is what it is //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

well for a trunk car anyway. I'm sure there are MUCH better ways of doing it than how I do though.

Be sure to secure it with a seatbelt //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I would not "suffocate" the port.

if you're worried about port noise then you can round the edges of the timber used for the port both inside the enclosure and outside

sealed is always better for frequency response provided it is built right ie its not to boomy

ported will more times than not give you at least a 3db gain but enclosure size is quite critical and port length as well. it depends what kind of music you listen to.

although a 3db gain may not seem to much 6db's is considered to be twice as loud to the human ear
