Hi.
I know this mainly depends on the driver itself, but usually they are optional (ported or sealed) and my question is what is better for an 8 inch- ported or sealed? I'm leaning toward sealed since I don't have much space for the box and I like tight bass (mid-bass in this case)....

depends on the subwoofer itself.

some subwoofers preform better in a ported enclosure while others are better in a sealed enclosure.

if your going sealed, i wouldnt go over 0.75 cubic feet

Thanks for restating my statement.

Thanks for giving us no information at all.

what driver are you using
what power are you giving it
what car is it going in
what do you want outta the enclosure (SPL or SQ)

The less info you give, the less info we respond with

If you want a single 8 to perform at any kind of decent level, I suggest you buy a good one and vent it.

He is on a budget, I gave him a deal on a 8", 25% cheaper than his last quote and it was too much for him. There are very few used 8" subs out there and even fewer with the specs he is interested in. Buy a good sub and vent it.

AAAAAAA

here are subs most likely in your price range that are actually really good.

This one will work in a really small box.

Most 8 inch subs will require almost as big of a box as a 10... keep that in mind.

Also, bad idea to want your sub to handle your midbase (unless it is stereo and up front since there are still lots of vocals and imiging cues around that area). You really shouldnt hope to rely on your sub for midbase, that's not how you should go about it.

Get better speakers for the front or do a door treatement (where you deaden it and seal up the big holes) as well as amplifing your front speakers will help.

1.- I'm looking to fill 60-100hz gap in my system (I have powered 6.5" and 6X9 allready also have tweeters) lows are the job for my 12".
2- I'm not looking into $400 speakers because I find it ridicilous.
3- the speaker is going to be mounted in the cabin so very limited space, if ported I will have to remove center console, If sealed Ill put it behind it.
MR2NR - sorry but I'm not spending $300 on a 8".
jalat- the question was simply are 8" better in sealed or ported boxes, from my experience bigger speaker performs better in ported box, here i might be wrong, BUT ported gives you lower tones and more efficiency. Therefore I was just checking if sealed will be better for the 8". Yes it depends on a driver but usually in manua; its optional (ported or sealed).
AAAAAAA- thnx for posting some links ill check them out.
I don't think I'll get a straight up answer here so close the thread. P.s. - I will probably go with sealed for SQ

just because you port and enclosure, doesnt mean it pounds lows with efficiency. i can port a ****ing 18" sub @ 50hz and burp 150's with it and it will stuggle on lows... where if i were to port a 10" around 30hz it wouldnt have an issue with lows.

think before you type bro

"bro" You are talking about tuning the box, I'm talking about the main principle of ported enclosure. The port allows air movement out of the box which makes the speaker (the system of speaker +enclosure) more efficient (more air movement- that's what the speaker is design for isn't?) now low tones use more cone displacement (air movement) then highs, then ported box WILL be better for lower tones (same speaker will be able to reach lower freq). Sealed box however encloses the air increasing the damping factor of the cone due to pressure difference. This will make it better for highs since they don't use that much displacement. don't make conclusions that by this idea, no box is better for lows since more air will be moved(technically yes since the famous "farting" is usually due to low frequencies that are very distorted, they aren't louder BUT lower, that cuz air will actually circulate arrround the cone.) And THAT'S what I meant.
