Conclusion: First off. It says JBL right on the dust cap. It's beautiful and massive. I want to give a good review. But I don't have cons. It sounds deep rattles everything that gets in it's way and is not gonna cr*p out anytime soon. Runnin it on a 900 watt pioneer amp and it isn't a power hungry beast. Well my lights dim very badly but it is a fifteen. If you don't love bass please get the 12 of this series. This is for bass heads only.
Conclusion: Testing my first sonotube build on a budget for home theater. Tried the first 9 minutes of Star trek, ITD. Testing with a condenser mic it recorded .8 % of the time between 16 to 27Hz. The box was tuned to 20Hz. Infrasonic filter set to 13Hz so the cone would not surpass it's excursion. It still picked up Hz from 8 to 15. I got in trouble for playing this in my apartment. Lot of audio people say you can't use a car sub for HT.
Summary: Superb value for money as are all JBL subwoofers.Genuine power handling as they recommend of up three times the RMS rating as long as it's clean and undistorted power. The only thing I have to complain about is their recommended box sizes,for this and all other current 15s they give 1.5 cu.ft as optimum sealed,whereas if you put the T/S parameters into a box calc program it gives 4.5 cu.ft.as the optimum sealed box size.I've got it in just over 3 cu.ft sealed with 1000...
Conclusion: I have had this sub for about 8 months and have had no problems at all. When i bought it it was only like $130 but now its $199. For what i paid it cant be beat. I also have 2 Memphis PR 15's and this JBL has much better sound quality. But for $200 i would probably buy a Type R. This sub is great though dont get me wrong. I have it in a ported Sonic sub box from this website as well. If it had a bigger box it would sound much better in my opinion.
Conclusion: I have had mine for about 2 months now. At first i received the singe voice coil version by mistake but i was able to ship it back fast and no cost to me (thanks sonic!) But anyway, i running 450 rms to it and i think it could handle at least 500. But even though i have it wired to 2 ohms i measured it with my multi-meter and its reading about 2.8.

Conclusion: I had two of these subwoofers and they really pound. I had them in a sealed enclosures and it was still shaking everything. This is a nice entry level subwoofer. Would reccomend this to anyone that us just getting into car audio.
Conclusion: I just bought this sub and gotta say it is CRUSHINN! Had some JBL's about 6yrs ago and they were good then and they HIT still. For the price this is a hella deal. I've got in a ported custom box built to make my trunk area flush and its awesome. will definitely buy more of these. awesome product!! A++++ and this company will answer all ur questions about the sub and wiring suggestions. very helpful.
Conclusion: It has been over a month since the install. They are just now breaking. I use 2 of them in a sealed (1.5 cubic ft per chamber) box. Matched the subs with JBL GTO 700.1 @ 2ohm. Gain is about 3/4 and bass boost less than half way. My ears hurt. They hit so hard the whole car(02 Accord 4dr) shakes so much. I get the great lows which i really wanted. I would recommend this subs to anyone. I do not have any cons so far. I will update my review in 6 months or so.
