12w6v2 enclosure

hello, i am about to install a 12w6v2, the JL audio webpage says that the recomended cubic feet for that subwoofer is 1.5 (slot ported)

If I build a 2.00 cubic feet enclosure (slot ported also) will it work just fine anyway?.... 

any comment please let me know.

Well, the reason is because I am dealing with a very small trunk and if I build the 1.5 cuft, I would need to extend a port length of 29 inches which is very complicated. (a few days ago I built an enclosure with 2 chamber of 1.5 cuft each and I suffered to make the port, you can watch it at: www.fotolog.com/infinitekaudio )

Well then, in my little experience I know that a ported enclosure of 2.00 cuft must has a 18 inches port length.

I just wanted to know if an enclosure like that wouldn't hurt my subwoofer and if i could obtaing great sound quality.

It's just that this is a work for myself. for my car, you know.

A 2cubic foot enclosure can have a port length of 3 inches...Its all relevant to your port area and desired tuning frequency.

This box would work perfect:

can you explain me the difference between a very long port length and a small port length?

and the difference between a small slot port and a bigger slot port?.. in this case you recommend it as 2.25?..

Hmm.  Never talked to coppellstereo before, but I've used these woofers and they like a *big* box.  Not a standard 12 I can assure you of that.  You should have absolutly no problem with 2cft ported enclosure..  furthermore building ported boxes is *very* easy.  I'll design one for you in WinISD so you won't have any doubt.

Okay, here is a text representation of the response of that woofer for a 2cft box with a 30hz tune.  I modeled a 35 hz tune as the cloak559 suggested, but I think this frequency produces a much better response curve.

See that?  Beautiful!  From 30 - 80hz this box will be +/-3db! Virtually flat!

Also, notice the port calculation?  Get a 2" PVC pipe from Home Depot and cut it to 2 8 inche lengths and, viola! you have your ports.  You can put one on each side of the woofer so it'll look nice.  And no, the 2 ports will not produce any port noise. 

Any questions?

Oh.  I reread ur post and you want a slot port? 

I can't stand all the carpentry involved there, but for the exact same tune in the same box, you're slot port would be 1"x12" and 13" long.  And no, that one won't produce port noise either.

Wow, very nice, man...

the only problem is that I am coming from my workplace (I´ve made the enclosure)

let me tell you what I did.

I considered the suggestions from cloak559 (I think he gave me one of the best explanations ever about slot port enclosure, I mean, without any complications).... he said that taking into account the port area I could obtain the port length (or I understood that), then my port height is 13.5 inches and the port width is 2 inches which = to 27sq. inches... And if he said that 30sq. inches = to 27.5 inches port length, then I made a three step operation and I deducted that my port length should be 25 inches.  (MEXICO; you gotta love it !!!, hahah )

My enclosure is e a little bit more than 2.00 cubic feet, because I had to consider the slot port and the used space of the subwoofer.

Is a Wedge box, well, I introduced the subwoofer and it sounds really great, amazing. I think JL audio is one of the best subwoofers ever. and it is just 400 watts rms.

Not like other brands that indicates thousands of watts.

I'll try to take some pictures tomorrow so you can see my work.

Anyway, I am going to consider that valious help you just provided me.

Can you tell me your method to calculate the slot port?.... or is the same method from cloak559.

just in case you prefer to chat.
