what is the difference between a ported subwoofer box and sealed subwoofer box? is one louder than the other? thanks for any info

kind of kinda not.
the ported box depends on how the box is. if its just a box with a hole on the side. its not really gonna matter. but if its made in a way that the air travels a cerain way to release the air makes the sub pound harder.

I Just Put A Regular Box Wit 2 10s In My Trunk It Bangs..

That's a lot of information to ask for, but this link should help you out.

From my experience....
Ported boxes tend to make a looser, more booming sound. More suited to slower bass sounds and less frequent beats.
Sealed boxes produce a much tighter, albeit quieter sound. They don't have as much hangtime though.
IMO Sealed>Ported

I had a sealed box and i drilled (2) 1/2" holes in the back. I noticed that my hair jumps up more.

Ported boxes have an air port that is "tuned" to a certain frequency. The enclosure will be louder at that specific frequency, which is why most ported boxes will "boom" when played with hip hop music. Most of that music is heavy in the 32-45Hz range, which is where most box ports are typically tuned to. A sealed box will be better for an SQ setup, as it will have a much flatter frequency curve. It will not really be particularly strong in any area.

Edit - A sealed enclosure will be extend further (play lower frequencies) than a ported enclosure. This is another reason it's preferred for SQ competition.

just curious is this ur personal info or did u read some research??? there are alot of SQ setups running vented boxs but for TRUE SQ u would actually do a IB setup. because actually sealed boxs do play louder at higher freqs. but a vented box give u double the out put of sealed boxs. but all in all there is not best box its all personal preference.

It was a little bit of both. I've tried both types of enclosures in vehicles, and found the frequency response was a lot flatter with a sealed enclosure, and sealed boxes extend a little lower. If you want to measure the SPL response wave with a microphone and the proper software to prove it, knock yourself out. I've done it before. Ported boxes will have a nice big bump at their tuned frequency.

When I was actually into the scene (granted, this was awhile ago) most people running SQ competition were using sealed enclosures because SQ judging at the time was partially based on a response curve. Not strictly the way you'd expect the "Sound Quality" class to be judged, I'll grant you, but that's the way they were doing it. Typically, the systems set up for a smooth response curve sound like ass. At the time, I thought "SQ" was sort of an oxymoronic term, considering the way it was being measured. Should have been called something like "Scientific Measurement Class."

Anyway, if I wanted tighter bass and deeper extension, I'd run a sealed system. I prefer a little more bump, so I typically run a slot-ported enclosure tuned to about 38Hz.

ive always heard ported sounds better
