Summary: Recently got this sub and man it hits hard. The sub does take time to break in but even at low volume levels slams. I have it in a ported box powered by a Jbl GTO501EZ its around 700w, but is 500rms giving the sub more than enough power putting it around 130% a perfect sweet spot for this 350rms sub. The sub hits its highs and lows very well, it definitely shows 1400w peak. The sub unlike many others has a very solid frame keeping it strong at higher volumes.
Pros: inexpensive, powerful,solid, hits every frequency
Cons: Stinks waiting for it to break in, but its the same for almost any sub
Summary: I took a shot, not knowing much about JBL, and it was worth it. Once I got it broken in with only a 750watt amp it was really great. Superb highs and fantastic lows. Once I got a 1000watt amp then it REALLY started making noise. It's got alot of kick in it, and just for one sub! I would recommend getting this, I'm really glad I did.
Pros: It's great if you want to have more than one subwoofer at a time, since there's dual voice coils which makes for easy wiring. It's got some weight to it, I've always liked a heavy subwoofer haha. It come with a JBL sticker! All around great sound and great quality. I'm satisfied
Cons: If you only use one (like I am) the dual voice coil wiring is not necessary. But it doesn't affect the product to me at all, you just have to make sure you wore it properly(which isn't hard, the book tells you how to do it) other than that, there's nothing I have to complain about
Summary: I got these to replace some 20 year old Kenwoods that are in a side-firing configuration in my bi-amped home speakers. They're perfect for my application, because I'm using a Behringer amp that works fine with 2 ohm stereo loads. The sensitivity seems true to spec, and is not hyped like some others' which will claim a higher level because it's in a car. This is actually 93db regardless of placement, and would be even a lot higher in a car.
Excerpt: I'm a sound tech at Stereo 2 Go in Long Beach Ca, We use a wide verity of subs in are installs and I've found that these GTO series subs are the best bang for the buck. I have a 2007 BMW 550i and seriously I plan to add two GTO1214D'S to my almost perfect stock system......We also have a zero return for blown speakers and that makes for a happy installer...
Summary: When I first got these subs they quit working the next day but I told amazon about it and they sent me 2 new ones without any problems and quick shipping on the return. I hooked up the new ones and they are some of the hardest hitting 12s I've herd. They also are very good when it comes to quality, very quick.

Summary: First - I am coming from a 12" Infinity Kappa sub, which as the only one I ever owned. It went down to 18hz!. I cannot seem to find one that get's that low anymore, but I knew from in the 80's when I was a child and someone gave my mother a pair of out time JBL 3-way speakers, that JBL was a brand I never forgot! Those speakers, which looked as if they were from the 70's, were heavy, had a tweeter with switches on them and the bass was deep and heavy!
Summary: I had bought one before from crutchfield, then I sold it. I went on here to buy two since I've always wanted to have two subs, and that one extra sub made a huuuuge difference!!!! My car is BUMPIN now, I could not be happier. It all paid off, I also got a 2 channel 1200 watt planet audio amp and it was much better than TWO different Sony 1200 watt amps. Pro tip, get thick wires to hook your sub up to your amp and stuff your box with polyester stuffing.
Summary: Wow I bought 2 thinking not that much power. But boy was I wrong. If it was 2 10" I'd be fine. But this is load an strong. Got it running off a Kenwood 1800 and its well enough. Going to buy a custom fit box make it cleaner.
