Everything about the sub is strong

There are none, the sub is strong in all ways

I have a 13W7 and I have it in a sealed fiberglass box. I love pulling up to the stop light and everyone looks over and they just have an expression on there face like, damn that sounds nice. I competed my sys with a friend and my 13W7 outdid his 15W6 on the meter.

Tightest, cleanest audiophile sound for those who care about quality.

Bug, heavy, and a little pricey but worth it. I actually had to take part of my trunk plastic to get it in there.

I replace my 2 JL W3 10 inch subs with the W7 and I am blown away by the difference. I thought the W7 would be about the same as the 2 tens and I couldn't be more wrong. The W7 in the factory vented enclosure is the cleanest, tightest sub I have ever heard. I used Cerwin Vega Strokers before and they were loud but no other sub sounds like this one. I am powering it with an MTX 81000D amp in a 1994 Mercedes E420 (I had to cut a hole in the back deck because the fuel tank blocks all bass )and this thing sings. I have a Soundstream Reference 614 on all MB Quart speakers and an Alpine 9811. This system sound so clean that I never want to get out of my car.

everything about it

gets tooo much attention and then people wanna steal your stuff!!

This is in my opinion the best sounding sub out, yea theres louder but not sounding this good, I have 1 13 in my 93 cougar and a 1000/1 on it and alot of dynomat and it is insane for one sub, last mic i hit 146.7 and now i have more dynomat and a 0 gauge power wire and a optima and a 190 amp altenator its probably hitting high 147 or 148.

Superior SQ. Simple yet stylish looks. Freakishly powerful with amazing clarity even at full throttle. Have I said SQ is simply amazing?!?! You just gotta hear it to believe it.

Like the ad says, it has the ability to warp you in and out of time and space. Also prepare to upgrade youre charging system as this baby is power hungry. I think Im gonna need to replace my alternator pretty soon :) Price is a lil steep but if you want the best there is, JL 13w7 is it. SQ is superior to all the subs that I have ever installed or used myself and as for SPL, there are few rivals. Box are expensive to built if you desire good quality and grilles are hard to find. So many bolts to retighten after awhile!!!

What can I say? This baby is a work of art. Im currently driving this sub in my lil Acura Legend with a RF Power 1500bd and it pounds like crazy without any distortion at even the highest volume. Anyone with heart problems I recommend staying away from this sub. It literally will make your heart jump out of your chest. The dishes in my kitchen rattles if I turn it 3/4 of the on in the driveway. On the other hand, if youre just going for a cruise late night, the JL 13w7 will soothe your soul. The SQ is uncomparable and far superior to any other sub I have ever heard. It is crystal clear, tight, and deep no matter what kind of music you listen to. From the slightest water drop to rock bands to all you Tupac lovers. I recommend this sub to all who could afford it. I love it when a big SUV pull over next to me and start playing their wimpy system. The FUN begins when they stare at me wondering how a small car could sound sooooo sweet >:) Oh yea, youre gonna need one hell of alot dynamat and check all your bolts every now and then.

JL for automobiles can be compared to Bose for home theather. Most common of a Lamborghini. If you got the money for it, GO GET IT!!! Or else, RF Power HX2 or Kicker 15L7s would do. Alpines or Polk MoMos would do on the lower budget end.
