1) yes
2) Depends on application and how much power through them.

well i have to disagree with you. Both sealed and ported perform very well in SQ. By SQ i mean it can play low, accurate and tight bass.

As i know those having a really good SQ in their car is using SEALED box. I only met 1 guy using PORTED.
Maybe ur taste is differnet with others.

Not looking for arguments (tired of it). Now if you can show me that ported are meant for SPL only and sealed meant for SQ I will gladly acknowledge it.
Before making such generalization pls prove your arguments with someting concrete. You can start with modeling out a same sub with the same cu^3 (take 1.00 cu.^3 for start) each ported and sealed. See which sub can play lower (with the same resistance and power through them). You will defitnitely see that sealed has higher Q than ported. SQ sub mostly aimed for 0.707 Q.
Kevin
I am surprise that you judge SPL or SQ with your eyes. All you see is installs.
gocitygo
sealed has better transient response than ported but that doesnt mean everything in SQ.
I did mine on sealed before and now ported. So i definitely know which can play lower freq. cleanly.

Friends, not need to to argue much, check the above link then we all will know better....

that doesnt give much info and also not very accurate.
The reason ported box are usually big is to increase efficientcy. Small enclosure usually will choke your sub to death and need very large amount of power.
If you would like more info and discussion about this, please check a thread i posted ported vs sealed (last few months). In that thread i posted some articles about why ppl go for ported and sealed and defining a t/s parameter of a sub.

yah......da lightningaudio link is not accurate.....appleyard is da truth....
wat ppls mean here is sealed is more preferrable for SQ
and ported is for SPL, no1 making da rule tat sealed must for SQ ok.....

Guys...be nice :D
Ok, question..for gocitygo..
1. What sub are you using? Do you have a specific model in mind?
2. For general difference, you can search the web, for specific difference, use winisd software to model an enclosure for you. Select the sub model you have/plan to have, and choose the enclosure, from there you can see and adjust the sub enclosure to suit your taste.
Please take note that some sub are specifically designed to perform in certain enclosure. Only some exceptional few are good sub that can perform in any enclosure type. So, the best idea is to follow the manufacturer's recommended sub enclosure type. Because they normally know's best what their sub can do. :D peace

i agree with you, the end it all will come down to preference. But generalization like Sealed is for SQ and ported for SPL is totally wrong.
I know a competitor hit 150+Db with sealed and someone who is using a brahma with ported enclosure.
T/S parameter will show you what sub is best for what enclosure but it doesnt meant it will suck in other enclosure.
Dique said:
thanks for the sacarstic compliments. I think you need to grow up. We all have our own opinion, if you cant accept mine then you dont have to act like kids.
btw....you have yet prove anything based on your argument.
So, is the Lightning Audio website's statement can be trusted or not? Anyway I got this from Rockford Fosgate website:
http://www.rockfordfosgate.com/scripts/rightnow.cfg/php.exe/enduser/fattach_get.php?p_sid=5Vx2Z7Th&p_tbl=9&p_id=185&p_created=1065552170
It has clearly stated advantages between 2 of them, but for me ,I still prefer vented as it can cool the voice coil. If still want a deeper bass or lower Hz from the sub just add a coil on it, the coil rating is 3.3 which I using now. I'm thinking how can a company that are selling ICE can come out a statement that is not that correct?

pls verify the sub that u r using.. reputable ones have recommendaton on the best type of enclosure, be it ported or sealed.. both have their pro and cons.. appleyard is correct, can't associate sq with ported or sealed.. the difference is 'control'

well....b4 u saying some1 acted like kid, please make sure urself acted mature enuf to make da statement, i'm not here to argue with u, so tat there is no argument in here, n if u think this is an argument, then i think u have to grow up n make ur mind clear wat's argument n wat's discussion.....
p/s: did i say sealed must for SQ n ported must be for SPL??? dun try to make ur own imagination n take it was other ppls answer. free ur mind..widely pls....
Dique said:
that is where you said sealed is for SQ.... high end SQ
Dique said:
generalization without any facts
Dique said:
i dont see any point to discuss further unless you have some facts in any of your post.
Tumpang this thread ....
My sub is Image Dynamics IDQ10 with a sealed box of 1.25/1.5 cu ft.(not sure) Actually the box was my old ported box but during the installation of the IDQ10, my installer suggested to sealed the box. According to http://www.teamrocs.com/reviews/speakers/idq10.htm, the recommendation offered by Image Dynamics is .65 cu. ft. sealed. Now, where can i find this ready made .65 cu ft sealed? I now can custom made one, but bit expensive lar
