Go with a bandpass box, you wont be disappointed...

i would say sealed because i had a ten that was hitting really hard so i bout the same speaker n a PORTED box because it was cheaper .. worst desion i ever made in my life .. all the bass comes out of the ported hole.

:this-guy_2:

From my experience ported boxes need less power to get more sound out of them but ones you start to crank it up a sealed box will hit harder and sound better but you'll need good power(an amp that can take it)

:this-guy::this-guy_2::this-guy_2::lame::lame:

Please let it die. I get all excited to when I see new posts in this forum only to see it is this one again.

Samu is correct, a ported box will play 'louder' across a specific frequency range when compared to the identical drivers in a sealed box with an identical, cheap amp. A sealed box however will play louder than a ported one with enough power because the sealed box controls driver movement which prevents overextending (blowing the speaker).

Its actaully over excursion of the woofer and it is dependant on the woofer. In theory a ported box should have a 3db gain over a sealed box however it is install depandant. If the box is properly built and tunned to spec. of the sub what not you will have no problem sounding as good or better than a sealed box with a ton more output. But PROPERLY is the key words. Prefabs are not worth shit and if your gains are set correctly via dmm or Oscope and have a subsonic filter or a sub that can handle the lows over excursion isnt a problem. I can play mine down to 10hrz all day and i put up 144db with minimal power all sealed up.

Its funny listening to every one talk about ported boxes that have to be tuned to the specs of the sub. Sure there are general rules of thumb and manufacturer recommendations, but when calculating port length for a specific port area and box volume, the actual Theile Small perameters are not used.

True, but the T/S parameters are used to determine if the driver will even work well in a vented enclosure, as well as what frequency that enclosure should be tuned to.

You are correct, but I would like to see some of these people try to calculate sealed or ported parameters, much less a band pass as some one recomended. You never really here about the the QTC or f3 of sealed enclosures and these are some of the easiest to caLculate

Do you think that some of the people here don't know how to properly calculate enclosures?

I think that most people in car audio shops don't know how to properly calculate enclosures.

My intent for the message is general. I know there are a lot of people who know how. I am not trying to point out any individuals.

That I would agree with. Also I just wish this thread would die.

I still have a mdf 2 12" enclosure for the spare tire compartment of an EG. Fits coupe for sure, hatch possibly. FREE FREE FREE FREE FREE... just PM me. And if you boot this because it should be in the classifieds... I think your minimum posting for classifieds is gay. I am on these forums very often, I just like to read... not so much of a poster.

i want to put 2 p3s shallow mount in my del sol what would be a beter box open or closed btw its gonna be fully custom

in the car not the trunk

What kind of music do you listen to?

Pm me already have a design that fits there

:google::google::google::google::google::google:

Wow could you possibly post a more worthless comment?

i listen to absolutly every thing rap rock metal thechno country old school everything that sounds good

I can make a custom enclosure... I've gone through schooling etc and have all of the correct tools and knowhow to make the most out of your space.

I have two rolling portfolios if you want to check them out, let me know and we can meet up!

Personally I would stick with a sealed enclosure

i had 2 p2s in a open box crappy amp and it hit harder than my p3s same amp same box so subs also help with box decisions

Sealed!

simple answer would be ported if the person making it knows what they are doing... if they dont i would go with a sealed. There is a lot of factors in building a box. port length, tuning frequency... but if tuned with the right measurements with the sub.. the sub will pound

It is a very vague question. you can have them hit equally as hard depending on the airspace in the box. however, sealed boxes almost always have a better response time which keeps your bass from sounding raspy. Not all subs are meant for ported boxes either. Some are meant to flex more than other so a ported box can make it easy to blow a fragile speaker. If you are going to make your own box i recommend using a speaker box encloser calculator to maximize your speakers efficiency and sound quality.

ported for sure
