whats the diffrence in sound/performance when it comes to a ported box or sealed box

 

Generally, a ported is loud, sealed is tight. More specifically, a ported box is tuned to be extremely efficient at a given frequency but can be lacking in the wide end of the frequency spectrum. Where as a sealed box may have less output (volume) but will generally be much cleaner.

It really comes down to what subs you're using, amount of power, space available, and most importantly the type of music you listen to most.

 

well i want some MTX...but if i want a much better quality sound and not just plain loudness i should go with a sealed?

 

yeah you would want sealed then.

 

No, a ported box can be louder, cleaner, and more accurate than a sealed box if it is built to specs for the subwoofer.

You cant just throw a pipe into a box and call it a day for ported, as where sealed boxes are much more flexible with similar frequency responses.

 

Look at the attatched graph:

Using the MTX recommended enclosure sizes for sealed(yellow) and vented(green) enclosures, you get an identical response curve BUT the vented box gives you almost a 10hz lower response That is the extended range without loss of quality.

The blue was me messing with the ported specs. Its too boomy

 

Maybe at the given tuned frequency, but if you think overall a ported box has as wide of a spectrum as a sealed...you're .

 

i just hooked up ONE of my subs in a sealed box built to specs, and its plenty deep for me

 

A ported box has an infinite flat frequency spectrum. It just happens that the boost frerquency will have a larger gain.

There are no negatives to a properly built ported box with a properly designed subwoofer.

My d3 runs a flat curve down to 25hz with a curve that peaks at + .5db in a ported box. Even toby said he surprised at how flat it was.

 

ok so let me get this straight...a ported box built to specs > then sealed built to specs
