These subs are beasts they are probably the loudest and best sounding sub for the money. they have a well rounded range of bass and the clarity of it is amazing.

Would recommend this to whoever wants bass. looks good and sounds good. i am thinking of getting another one.

I purchased a 13W7 and a ported box tuned to jl specs and this one sub hits very hard! In a 01 civic the 13 hits pretty tight when needed and super low and very deep. The sound quality is pretty remarkable! I'm running a JL 1000 on it and it loves it. I previously was running two MTX thunder 12 7500's and this one sub destroys them on the same amp. However on some music I still miss the MTX's sound. The only real drawback to the 13w7 would be the weight in a good box is close to 100 pounds, I would recommend a high output alternator and a XS Power battery and 1 gauge wire to maximize the full potential.

I have this thing in a custom 13w7 box in the back of my Toyota Land Cruiser, and it is ridiculous!!! That truck has a lot of air space inside, and that speaker fills it up and then some. It's just small enough to keep up with the double bass drums in metal (and it sounds like a machine gun), but so deep that it sounds like an earthquake from down the street when I'm listening to rap or whatever thumps. I would buy another but I dont want to go deaf and shatter my windows.

I have 3 of these subs in my yukon running on a rf bd1500 1 at .75 ohms. Each sub is getting a lil over 2100 watts absolutely clean and loud. there is a reason JL has not changed theses subs in 10 years there is no need i play at full volume all the time an for the first time in 6 years i blew one. 365$ to jl and i get re-coned back in business all i can say is this sub is the best sub ive ever heard. There are alot of other subs out there that claim to be louder an most of them are 18's an need 6000 watts. I promise 3 jls running on 2000 watts each is gonna be louder then any 18.

This is one of the best subwoofers ive ever heard. I have one hooked up in my car with a 1000/1v2 and it bangs hard! ive never heard anything like it. The only down side is they are a little spendy and are really heavy. But are definatly worth the money. If you can get your hands on one of these, they sound great and bump hard. Plus it will make everyone in your neighborhood jealous.
