Sealed or vented??? Whats the pros and cons of having a sealed L7 or a vented L7.

 

Vented, cause women like it

Vented is louder and lower, what else do you need.

 

I asked the same question to a guy that works at a local stereo shop and he said because I have a hatchback, I want more sound pressure, so I should stay with my sealed box.

 

cool....anyone else

What was that guy smoking? Unless you have too many subs to build a proper ported box, sealed will not outperform for sound pressure. For a single sub setup, then there is no reason to be sealed.

EDIT: Unless you are a hard core SQ guy

What he said man....single subs must be ported to sound good.

 

Vented is GOOOOOOOOOOOD

 

I agree that you should go with a vented box. However it must be a properly designed vented box. A vented box will play louder and lower. The reason that someone may have recommended a sealed box for a hatchback is because of port noise. If you use a well designed port (preferably with flares on both ends) it will minimize port noise and you will not even notice it. Another reason to go with a vented box is efficiency. You will get much more with less power out of a vented enclosure as well.

naturally and safely, a sealed box will play lower than a ported box (unless you tune the port to say 1hz. LOL!

My bass cd does not hit 1hz

A sealed box probably will not outperform a well designed/tuned ported box in the audible range. It may be louder below 20 if you have a 35hz tune for example, but the sealed box gets owned from 50-20

To the original poster, ported boxes will have a faster dropoff below tuning frequency. So if you like shaking sheet metal, tune it low.

So what I should have said is that a ported box will play louder down to where it matters. The human ear can only hear on an average down to like 20Hz so anything below that is pointless. And most music will never play that low at all.
I thought what I was saying would help out the average joe. It's easier to explain it that way. You have to realize that I'm used to dealing with the morons that come into my store. Most of you on here are much smarter than they are and sometimes I forget that. My apologies.

 

Ported goes lower.

 

Ported will definitly be louder and lower, just make sure that you have a subsonic filter. I have seen many solobarics come back that were in a ported box due to the fact that they lose control below their tuning frequency.

 

if you are listening to music, make it sealed because it will be more musical. but if you just want it to be loud, port it. just dont forget to use a subsonic filter if you decide to port the box.

 

I just installed an L7 in my buddies car in a ported box, a kicker pre fab, and it sounded awsome! Deep warm bass, not just loud.

 

I'm a newb and it wouldn't let me vote but I would go with a sealed box. As stated above and elsewhere, sealed performs better across the entire spectrum 200 hz- 15 hz. Anything below about 18 hz is not audible to a human easr and is only perceived as vibration to the rest of the body so all you'll get out of sub 15 hz is rattle rattle rattle from any loose part in your car without the sound of bass covering it up. Go with something that sounds good no matter what music you are playing.

Put me out of my misery please

Why is this so?

 

thanks for the info....i believe my amp should have a subsonic filter

my friend my friend my friend..a sealed box will extend LOWER, but won't be LOUDER. you're mixing up word man..get some coffee

 

Because Venting enclosures is Getto! We don't drive Caddy's

You mispelled ghetto

A picture is worth a thousand. It may be easier for everyone to see what is happening. The following model is a 12" TDX. Blue is is 2 cubes tuned to 26, orange is 2 cubes sealed, yellow is 1 cube sealed. 20-25hz is the threshold of hearing for humans.

 

thanks for the info guys....but im still stuck in the middle...LOL

 

If you are building your own box, make one of each A small sealed "travel box" is nice to have.
