Looking for some advice on whether to go with a sealed or ported enclosure for 12w6v2 driven by an HD750/1 amp...I listen to mostly hip hop, but a good amount of rock as well. I love the low end bass... not sure if that helps much. Any info will be greatly appreciated.

Depends what ur looking for... Ported will IMO always sound better then sealed. The only Problem is that the Ported box will be bigger and take up a lot of trunk space if done correctly. Seal takes less trunk space and still hits hard, just not as hard as a ported box. To me it only comes done to size. If you need a lot of trunk space go sealed if not go ported. I recommend Ported, I love these type of enclosures

I hate ported boxes in trunks. The sound like they are ported twice to me... one from the box and once for the trunk. I think that they are noisy and lack any kind of quality. Plus, if you point them backwards, the box blocks most of the useful space to get the sound back into the cabin. However, I love them in hatches and SUVs.

You are going to get 100 different opinions on this from 50 people. Only you can decide what you need to do. Either should sound pretty good and the W6 is capable of being good in either, so you cannot really go wrong.

The 750/1 will destroy a single W6 if you don't watch it. Unless you have a pair, then be careful with it.

This.

And I prefer sealed.

ported w/ low tune best of both worlds IMO

Im running a 12w6v2 in a sealed box with the Slash 500/1 for an amp. I have always been a fan of sealed because it offers a nice tight bass. This is important in the TL, I think, because our mid bass sucks. It allows me to run a higher freq. range without any sort of distortion. The W6 is a capable driver that will hit all the notes accurately, whether its a low freq. or a high freq. If you live in the area let me know if you want to hear it before hand.

Also, I agree with the 750/1 being too much for the sub. You wont be utilizing the amp at all so def either get a 12w7 or a smaller amp. I would get a 12w7 if I was in your shoes.

Ported tuned low

W7 is more of an spl driver that can get pretty sloppy at higher levels. Not a fan of what I heard at least.

OP- Since you're only running one, I'd go with a ported box tuned 28-32hz. DO NOT buy pre-made boxes as they're tuned up in the 40's and will result in boomy and just plain shitty reproduction. Keep your gain low as you won't need all of that amp...plus ported is efficient. Good luck and post up pics and your impressions when you get done

That had to be a shit install. The W7 was basically the first low distortion, high linearity, high output driver on the market.

The entire purpose of it's design was to improve BL linearity and reduce distortion while also improving output capabilities by increasing cone area and maintaining a high Xmax (which aside from shear output, the benefits of high displacement capabilities are also a benefit from a "sound quality" perspective as well). It takes a lot to make that driver sound bad.


Chances are, it was probably a fault of the installation, enclosure, tuning and/or setup and settings.

Agreed. As long as you have a little eq available to flatten some of the low end (unless you like it like that). My 12W6s sounded better ported than sealed, not to mention they required less power.

To the others, ported can offer just as "tight" of bass, reach very low, and do so while requiring less power.

I hate cars

Agreed. The W7 is an SQ driver that gets loud imo.

Im flabbergasted to hear w7 and distortion the same sentence. hahah

If I had to choose a sub to pair with that amp, it would prob be the RE Audio XXX 12. The only draw back is that driver requires a huge box, sealed or ported.

Its always going to be about personal preference. The w6 is a popular sub so i think you should look in your area to see if there are any available that you can listen too.

xxx 12 needs like 7 cubes sealed.

^ took me a second... awesome.

Back to the W6... have you made a choice?

After you make your choice, be sure and wire it up correctly. Take the pre-amp signal for the sub and wire it directly into some RCAs. DO NOT use a line output converter or it will cut most of your bass with signal loss. If you take the signal post-amp, it appears to be -3 to -6 db under 40-45hz (probably to protect the stock sub), so even that signal is not idea either. You can seriously have a bad experience with some good gear if you wire it up wrong with a terrible signal.

Okay...I'm going with the XD600/1 amp in a sealed box...now I just gotta decide whether I want the left rear corner box or fab one to pass through the rear armrest, I'm leaning towards fabing one up. Would you guys recommend a battery in the trunk, or will the factory one push this with no issues? I don't want my headlites dimming with my music.

By the way...I appreciate everyone's input and assistance with this.

Not sure how close you are to this...but in the FS section there is 2 IDQ v3's w/ Sundown 1500 for $400....jump on that if you're close!!

What is the efficiency of the XD600/1? Does JL even offer this as a stat? Is it like the 500/1 or 1000/1, or is it a real D class? If it is a real D class, then it is OK on stock power. If it is a power hog like the 500/1 and 1000/1, then you might need some beefing up - it will probably be OK anyway though.

If it is like the 500/1 and 1000/1, then I would get a different amp.

1% THD? Dang, that is high. You sure that this is a good amp? Just because it is JL doesn't mean that it is good. It might be good - I have never had one. Check around.

In any case, do your big 3 with at least 4 gauge wire.

I remember bikinpunk over on DIYMA tested them and they're a real class D, one of the more efficient ones. They are very good amps. Just because it's JL doesn't mean it's bad. Even the best speakers produce way more than 1% distortion, 1% with an amp will never be audible. I'm going off of a bad memory here but I think the only amp that was more efficient was the ZED Leviathan.....

From the product review section: http://www.diymobileaudio.com/forum/...o-hd-amps.html

I'm ordering the Leviathan next friday. 150wx6 @4ohms, 300x6 @2ohm 600wx3 bridged. Probably going to get rid of the Mac.

Nevermind, I thought he said the HD line. I have two friends running the XDs. I would rate them as "OK". Get them if you need the space, there might be better amps out there if space isn't your number one concern. As a sub amp I'm sure it would do fine.

kirill1221

I would probably stay away from the xd series if youre going to stay in the JL lineup. The great thing about their Slash series and their HD series is they have this thing called RIPPS (Or RIPS, don't remember) power supply and it essentially prevents too much consumption of the battery. They have built in capacitors that handle that stuff which is why its bad to run a cap with any of those series subs.

I personally love my 12w6 and noticed an immediate difference when I switched from an alpine mrp 500 to the slash 500/1 in terms of power consumption and sound.

I also agree with above. Def take the signal before the stock amp and run straight to the RCA jack in the amp. This offers a slightly lover signal level but you won't lose any sound through a LOC.

Okay...so I just purchased the jl slash 500/1v2...sealed box is almost complete. Gonna run my wires while I'm putting the damplifier and luxuryliner down...put up some pics when all finished. This is my first box build so I didn't want to bore you'll with pics of my simple box.
