Hard choice ,sealed 13w7 or a ported 12w7?
 

Hard choice to make can you guys please give me your thoughts and prefences :D

I thought that the size above a 12 in the w7 line was a 13.5? Do they have a 13 and a 13.5?? Or am I totaly off base here?

Yup ,its a 13.5 I always forget about the .5 :roll:

OK I was just wondering... I'm still new to the whole sub thing and the 13.5 came out of left field at me when I first hear about it... I was just making sure I kind understood what the guy was talking about. :lol:

12w7 in sealed box. The port will only make it sound horrid, it'll be more then enough volume either way.

Are you saying you'd go for the 12w7 sealed over the 13.5 sealed?

i heard the jl 12w7 in a jl ported box at Teckla Car Audio in Savage, MN. Even though it was ported, WOW! Still accurate. I'd still rather go with a sealed box, but this huge ported box still sounded nice.

they also had a 8w7 i think and that thing was hitting extremely low frequencies. it was bumping harder of a 600 w crossfire amp than some dual eclipse sub setups, dual jl sub setups.....

Basically JL W7s are amazing

I'd prefer a perfectly setup sealed box. Don't buy a prefab for that behemoth either. I'd try to keep the size as small as possible, as i'm sure that sub requires bigger boxes then most, and more power, as you get bigger.

Are the boxes already made, thats why one is sealed & one is ported? Ported boxes can sound nice if they are properly tuned. Sealed boxes are the more popular and easier to make thats why most go with it.

I was looking at the JL boxes they have a ported 12w7 and a sealed 13.5" that I was interested in,Im pretty sure the jl boxes would be tuned to specs,could be wrong but I'll check their website.

Well I vote SEALED either sub. But first question is what amps are you going to be running. Maybe wattage will make the choice. Personally I LOVE MY 2 10W7's!!! :D I perfer little tighter bass and like the responce of a 10 over 12 or bigger. My 10's play plenty low enough, not missing any notes here. I beleive that the bigger the sub the sloppier it will play, but a 13.5w7 with proper wattage will POUND so HARD that you wont be able to notice the slop cause your whole car is going to vibrate. Hope you plan on some series sound dampening.

You would think the JL boxes are pretty good, I 'm not saying there not but my last setup was the JL PRO-wedge with 2 10w3's and I blew a sub ever year off the recomended wattage. I might of turned up the boost and gains once and a while for fun though. Gotta love a warrenty. I got 5 years on everything in my car right now. Kinda want to blow a w7 just to get a new one.

For amps im going to go with jl's 1000/1 or a zapco 2 channel ? ampage will be around 1000 watts rms.Guess im going to go sealed, I would also love to do a custom setup ,but I have kids with big toys and strollers so i have to be able to take subs out frequently :banghead: So i think im going to go for a 13.5 jl prefab box and a 1000/1. Im wonder 2 -12 w7's will fit in my my old kicker prefab box :idea:

Ya know, i got a power wedge dealy with a big DEI amp pushing them, and it's making them work very nicely.

this is the box i heard

the H.O. wedge w7
impressed the shit outta me for a "ported" box

Thats one of the boxes I was talking about , Looks good to boot :wink: ,Here the other box I was thinking about , anybody have or see one of these,they look pretty well built http://www.subzoneusa.com/images/12W7ashadow.jpg

That does look well built, you'll need something that's VERY strong, heavy, and you'll need to bolt it down so that doesn't go flying around at all.

The JL w7 13.5" box that they offer at stores is a behemoth am I right... because its just a bad use of space.

Man :? ,I dont know about Jl subs anymore. Check these babies out,very good reviews on car audio forums and cheaper as well :) http://www.respl.com the re xxx are pretty serious subs as well.

I've heard good stuff too, but you definetly don't have a nice company to back you up, Their website was last updated on waaaay back in 2003. They do have a good rep, but i'm still behind the w7. Did you check out adire audio?

Alright im sticking with JL, Im getting one 13w7 in a sealed enclosure along with a 1000/1 to run the sub and either a 300/4 or a 450/4 for my components and 6x9's,Im going to upgrade my power wire from 4 gauge to 2 gauge and get a 2.o farad cap for extra support.Ordered a 200 amp alt from TY last week ,cant wait :arcade: .Im still looking online for a good deal on the dynamat extreme bulk pack.

i'm pretty sure you won't regret going with that JL.

for the dynamat, check out ikesound.com or thezeb.com

Or look around on ebay if you're down with that!

I think you'll be quite happy with your selcetion 13.5w7 and 1000/1 will definilty have some kick to it. Either 300/4 or 450/4 are nice. I recomend the 450/4 if you get some nice front components, the extra wattage to the front sound stage is worth a ton to the imaging/staging when you got a big w7 in the back. :D

I can't wait to see this when its done!! :)

Hehe,Its not gonna be anything pretty because I have kids and have to put tons of stuff in the trunk,therefore is gonna be a simple prefab jl box and an amp rack,so I can easily take the system out and put her back in just the same :wink:

good luck let us know how it turns out
