ported whould work but, in my 2003 expedion I have 4 12's sealed and it's perfect cause the big cabin of the SUV is like one big ported box...know....and 2 subs whould be better...just my 2 cents

why does the number of subs determine the type of enclosure?

exactly, it doesn't matter if you have 1 or 20 subs, i'd go ported unless your going for mainly sq, then i'd do sealed
ported is a good combo of both spl and sq so i recommend ported

also to jay956, ported gives you a louder sound, sealed gives you a little more accurate and a lil more sq, but overall you get more sound from ported

I'd go sealed with the w7. They sound great when they are sealed.

I'm so confused lol. Don't know what to do. :banghead: All I know is that I want the best sound possible. So maybe I should go ported? Or maybe sealed? :wow: We'll get to the bottom of this for sure. Thanks for all the replys you've been propped

yea go sealed, plus box will be cheaper/easier to build if you do it.

Sealed Will Be More Accurate And Sound Really Good. However If U Tryin To Beat Down The Block, Ported Will Win Out By Far With The Jl. W7' S Are By Far No Slouch In A Ported Enclosure Though. I Would Say If U Listen To Various Types Of Music And Like Bass For A Fuller Sound Go With Sealed But If U Listen Mostly One Type Of Music Or Just Want To Bang Go With Ported (the Idea Is To Tune The Port With The Sound U Are Looking For But That Doesnt Always Work With Different Music But The W7 Ported Puts Out Nice Across The Board If Tuned Right).

By The Way, The Number Of Subs Has Nothing To Do With The Enclosure Being Sealed Or Ported. Call Jl And They Can Vouch For That. The Only Factor Would Be Enclosure Size (a Ported Enclosure Would Be Larger). 2 Subs Doesnt Mean U Have To Switch. Thats Stupid

I could give two sh*ts what JL says...One sub in a ported box has bad speaker response where 2 subs in a ported box has very good speaker response cause the pressure from one sub equalizes the pressure from the other sub which in turn balances them to bump in unison....SPEAKERS ARE BEST IN EVEN # PAIRS....TRUST ME!!!!!

EDIT: Plus 2 Subs Has That s3xy.....:D

Where do you get your facts from because everything you said is wrong and ignorant. 1 sub in a ported box does not have bad response. You would get more output of 1 sub in a ported box than you would with 1 sub in a sealed box. It all depends on how you want your sound, how much room you have, and how much power you are feeding the sub.

For a sealed box, it's the most easy to make and requires less room, and it will have good low frequency extension, but might not have the best low frequency extension. If you don't have much room for a box, then sealed would be the one you'll want. Plus sealed is more SQ than SPL/SQL.

For ported boxes it will generally have a better low frequency extension for a given response shape, but would require a large enclosure. If you made the enclosure as small as the sealed enclosure, but ported it to gain the low frequency response, the output would deviate from the desired flat response.

If you go ported, here's some tuning options.
Sound Quality (SQ) : 20 up to 28 Hz.
Sound Quality Loudness (SQL) : 30 up to 35 Hz
Sound Pressure Level (SPL) : 40 up to 80 Hz (test tones are played rather than normal music, to avoid Low frequencies, which damages the speaker).
Its commonly used for competition purpose. and not everyday driving. (unless you like listening to test tones for everyday driving).

So if you do go ported, there's some options to look into. If it were me I'd go sealed mainly because I love SQ more than loudness. That single dub7 will sound good in a big SUV in a sealed box.

EVERYONE STAND DOWN. THE AUTHOR ON CAR AUDIO HAS SPOKEN ONCE AGAIN. WHO GIVES A fu*k ABOUT WHAT THE DESIGNERS OF THE SUB THINK. SURE THEY DEVELOPED, TESTED, AND KNOW EVERYTHING THERE IS TO KNOW ABOUT THIER PRODUCT BUT THERE HAS TO BE SOME KID ON BOXDEN WHO KNOWS BETTER. MAYBE A GED OR HIGHSCHOOL DIPLOMA IS ALL NEEDED TO BE AN EXPERT AT THIS THING (EVEN IF U PROBALLY NEVER OWNED THE THING TO BEGIN WITH AND IF SO, NEVER APPLIED EVERY POSSIBLE APPLICATION TO KNOW WHAT WORKS BEST FOR IT).

ILL HAVE TO WRITE THAT DOWN THOUGH. U SAY THE RULE IS THAT ONE PORTED SUB CANT SOUND GOOD. U NEED ANOTHER TO "EQUALIZE THE AIR PRESSURE" RIGHT? THATS WHEN THEY "BUMP IN UNISON".

U MUST BE AN a.ssISTANT MANAGER AT BEST BUY OR CIRCUT CITY:sick:

OH YEA I ALMOST FORGOT........U GET "THAT s3xY" FROM 2 SUBS

ported to me just don't sound right....

I was told by a few people that you never put one sub in a ported box cause of poor speaker response and Sq is weak...If i'm wrong i'm wrong but, i will never use a ported box...:D
