I cant decide if i want to go with a sealed or a ported box for my 12w6v2. I listen to rap and hard rock. I want clean crisp bass for the rock and deep pounding bass for the rap. what do you all think? I drive an 03 camry if that helps anything.

It'll pound nice either way. I've been punching in and ****ing my box program (luckly it's the one manufacters use) it can estimate approx dB. and much more.
Would you like it to have a low cut-off freq.? w/ extended bass. I mean you said crisp sounding so id think youd rather a lower cut-off freq. w/ extended bass.

lemme know

The w6 is a sq woofer, not a spl woofer. If you're going to port it tune it really low. However, if it was me I would not port it. They have amazing sq sealed.

I have a pair of 10s, at first I was gonna port them, but then I decided to try them sealed first.
It is a ridiculous small box and I'm still impress by the sound that's coming out of these two little things :eek: .
For some reason I think they are meant to be sealed, these are not boom boom speakers :nono: , is that what you want then these are not for you.

Keep them seal.

the difference in the cut-off freq is a bit diff between ported(about20.01Hz) @ 26.3166Hz Tune. and sealed (37.45Hz). however the size is tremndously different. these are just basic comp gen. boxes nothing special

i would go like 2-2.5 cubes ported at 32hz

2.25 cu.ft. @ 32Hz would cut-off about 26.56 Hz and have an average of about 115 Db @ RMS (30Hz - 90Hz) and wouldn't max out much higher

Keep it sealed it's a w6.

He is ABSOLUTELY RIGHT! Dude the 12W6 is a SOUND QUALITY sub woofer! Eric Holdaway ,with CA&E, said the 12W6 is the best sounding sub woofer that he has tested!
I listen to the same music u do plus throw in some country and I'm on my third enclosure with my W6's. The first was a JL box witch I had when I was just using one 12W6.It gave me some tight,natural sounding bass! Then I got the second so I let my buddy talk me into building a ported box. It was loud but the sound quality that the w6 is know for was NOT there. I just finished my current enclosure about 2 weeks ago. It's a 2.5 cu. ft. sealed box and I'm VERY HAPPY with it! I was at my buddy's house yesterday & I had in a Nickleback disc. One of his neighbors from two houses down came over just to see what speakers I had. He was saying how these days when u hear a loud system that all u mostly hear is boom & more boom but how impressed he was with how all the different frequencies blended together so well & how the bass sounded tight and natural instead of just loud "BOOM".
Don't let the sealed enclosure fool u though, when I dropped the second W6 in & the second 500/1 we tested the SPL with a SPL meter, with the mic at the windshield, and I hit 148.3!! Not too shaby at all if u ask me! Now I had the amps turned up a little more than I usually do just to see what kind of SPL I have.
Bottom line is this- u have a VERY nice sound quality sub woofer, why not put it in an enclosure that will let it do what it's made to do, you WON'T be disappointed!

Well its up to you as rlcowboy says its a sound quaility sub and i would keep it sealed.Right now i have mines in a 2.0 cft @ 31 hz and ill tell you this thing is insanely loud for wat it is compared to other setups that i heard people often wonder if i had 2 subs but the detail in some music just aint there and the really really low end isnt impressive at all.Btw the sorta music you listen too i dont think you be sacrificing alot going ported not much sq bass in rap im not too familiar with hard rock tho but dont get me wrong its still sounds amazinely crisp ported but its not at its best.


P.s im trying it in my old sealed box later today imma let u kno how it goes

Ill be doing mine 3 @ 33, first. Ill try a sealed box later. Ill be building this week. Sometime, hopefully tomorrow if the weather is decent.

i have 2 12w6v's in a ported box. im planning on buying a sealed box to see the differences.. let me know updates.

The RIGHT ported enclosure won't let you down either. That said most people don't have the space to put these in the right ported enclosure and most end up in a ported box that is way too small and tuned way too high. A 32hz tuning results in a 3dB peak around 45hz. The sub wants a sub 25hz tuning to play flat. It also wants about 4 cf per driver.

what is the right sealed enclosure, to you?

i definitely dont have 8cf yo give up hahaha. oh well. i will have to deal with it.

One of these days I am going to take the time to learn to compute appropriate box size on my own. I know that JL's recommended box sizes are different than the ones you just suggested. I am not saying you are right or wrong in this particular case (I just don't know).

However, I am under the impression that many companies underestimate the appropriate size box for their subs. I don't know whether this is for marketing purposes or what. Or perhaps the recommended size represents a compromise of some sort to fit the broadest range of listening tastes.

I recall once reading where Ologyaudio was discussing what size he felt should be used for BA's G5 sub. BA was saying 1^ sealed. Ology was saying that he would recommend puttting it in a much larger enclosure -- perhaps 2.2^ if I remember correctly.

Most manufacturers recommend a compromise box. When it comes to ported boxes they tyipcally recommend a small efficient box. The resulting output enphasizes one particular freq in the 40-50 hz range. The typical person going with the recommended box is usually looking for output over fidelity so it makes sense for the company to spec out a box that gives the average consumer what they want. Once you get beyond just wanting output and really start to care more about quality rather than quantity, you are usually beyond the level of just going with what the manufacturer recommends.

BTW I mis-typed something in the post quoted above. It has been fixed in the original post.

Oh ok. That makes more sense now since the correction :). So I guess my question is pointless now. Well not really, what size sealed box would you recommend for these subs. I believe JL recommends 1.25 per sub.

JL's recc. or right on par with the subs specs.

JLs sealed box specs are almost always right at a .9 Qtc alignment which is a good in-car alignment.

The first box I built for my w 12W6's was built right to JL's specs. I felt the low end was kind of ******, so built a new box. I built my new box to about 1.4cuft per driver AFTER displacement. It definitely helped the low end, but I still feel it is missing something. I've been thinking about building a ported box and tuning really low to see how it reacts to that. The SQ on these guys are amazing, and I really don't want to lose that.

My 12w6v2 is in a sealed box and it's perfect for rock music. For rap or other deep bass music, it's still quite impressive.

I had to dig up this thread, to see if any of you that have tried both enclosure types have a preference

Im curious as well... I have a 12w6v2 and deciding what kind of box to put it in... I called JL and they told me to put it in a 1.5 cubic foot box with a 30" port with 18.75 sq in port size...I listen to all kinds of music, but mostly rap... Ideas?

These things (12w6v2) can sound extremely well in a smaller sealed enclosure. They don't need nearly as much as some others. I would stay with a sealed box IMO.

Digging up an old thread a bit...

I'm curious to hear any new thoughts on different sealed box sizes people recommend that they have tried in the past several months for the 12w6v2.
