JBL Full-Range Kit with 6½" Speakers, 12" Subwoofer and Amplifier Wiring Kit

Awesome sound and underrated RMS power handling.

these subwoofers really really kick out the tunes. the powerhandling is way underrated and the can definitly handle more power than they say. i currently have them wired for 2 ohms and 1000 watts RMS between 2 of these and now my rear view mirror looks down when i crank the volume. these subs really get the job done and sound clean and undistorted the whole way through. also, they produce low notes beyond the rated 27Hertz.

Great buy!

This is a fantastic buy. Amazing for the price.

great buy

Bought 2 of these a few a days ago. Awesome subs. Great sound quality and they hit!! I have them in a sealled box. in a 99 eclipse. and the make my rear view mirror fall till it faces down. I can't wait to get a 600rms amp and really push these things. I would def recomend these subs. especially it your on a budget.

Just what I was looking for!

This amp is amazing and I have to agree the 3 channel is perfect for what I need and this amp is amazing. Pumps out clean power and fit just where I needed it to. (Though it is bigger than it looks in the pictures, just check before if it will fit where you want it to.)

Mounted on my spare tire in my scion tc. Powering the nvx component set and the nvx v subwoofer 500rms at 2omhs and it slams! (I'm very happy about the nvx products as well)

Sonic is the best if you don't already know by now, but back to the amp. The "EZ" setting gain LEDs are extremely helpful and I really enjoy that I have that feature. Also this puts out amazing power and only takes an 8 guage wire kit which was perfect. I am a big fan of JBL and NVX now. This amp is more that likely putting out more than it's rated for, just clean power. Very, very happy.

Personal Experience Says This Is One Excellent value

Hi, everyone, welcome to this review. Let me start this off with just telling a little bit about myself and my audio background. Being an Electrical Engineer, efficient and well-thought out design is key to any and all products which I consume. I've gone through the all the stereo in a boxes and decided to step things up and design a home system from the ground up each component carefully hand picked on a budget of $500 for the whole system.
The system: This 12" rated subwoofer driver was chosen to go into my hand built 3/4" MDF ported 2.05 cubic foot enclosure (not including port or driver displacement). It is driven by an MB Quart Discus 4-channel A/B amplifier with channels 3 & 4 bridged, feeding 320 watts of rated power. The amp feeds off a 400 watt continuous rated DC power supply. Though I rarely take advantage of all the available power.
Performance: While I only have personal experience with a few budget subwoofer drivers, I am a musician with a keen ear for sound nuances (I'm also somewhat of a bass fiend). I own earbuds and headphones that produce very flat sub bass curves, easily down to 20 hz, these can outdo any 12" subwoofer driver in below 35 hz sub bass, So I know what to look for. After more than 100 hours of listening with every possible musical genre, I can say that this performs as well as expectations. My main focus in a sub driver was to have very accurate and LOW frequency reproduction. Now, anyone with experience in these matters knows that ratings don't necessarily line up with reality. (Notice there is no threshold mentioned [such as +/- 3 dB]... vague ratings are hard to get an accurate idea of actual performance. However other reviews around the internet, along with the a look at the manufacturer supplied frequency response graphs, seemed to also give me the impression that this driver stands above the rest in low frequencies. Now, it all depends on the acoustic environment obviously. A car is much friendlier to low frequency reproduction than a big room, hence the reason for choosing this driver. Using my own tests with test tones and the sub placed optimally for the listening vantage point to be squarely in an anti-node for very low sub-bass frequencies (below 40 hz), I came up with, to my ear, about 33 to 35 hz accurate frequency reproduction and topping out slightly above 100 hz --- this is with the threshold being half the peak volume. As far as I know this is quite good for a setup such as mine. A 12" Pioneer sub of equal cost and same setup was much higher at this threshold (about 40-42 hz). At sub frequencies this low, the difference is very noticeable in bass music tracks, and even in the low rumble of a concert bass drum, however metal/rock/country/pop or what have you, the difference will be unnoticeable.
In summation: this driver performs very well at it's intended purpose low frequency reproduction, in the price range of less than $100. If you intend to burp out 40-70 hz bass at incredible dB, you could probably do better (get a low-end kicker model or some such, they might handle more power, but it seems some of those drivers don't respond well in ultra sub-bass). Very happy with this purchase.

Bass On A Budget

I recommend this sub for anybody who just want to shake the inside of they car with a budget.Hook it up to a 300w RMS Mono and a custom vented box and your done and please don't dream of shaking your neighbors windows. But anyway good value from JBL.

WoW!

These subs are awesome for the value. Can't get any better than this! I love Sonic Electronix!

father sound

en una sola palabra fantasticos- hi fidelity sound, para mis oidos, y su presentacion es linda, y digna de excibicion, very happy.

Best bang for the buck

A subwoofer with 14mm of REAL xmax for this price is unbelievable. It wasn't long ago a subwoofer of this quality would set you back quite a lot. The build quality is excellent from the heavy gauge stamped basket to the rubber coasted tinsel leads. All of the glue joints seemed neat and clean, I have no reason to believe this sub won't last me the life of my car.

In my opinion this woofer is completely underrated at 275W RMS. A 2" coil with vented pole piece means thermal compression should be minimal. A large linear throw, and progressive spider to handle high power transient peaks means the woofer is mechanically robust. As long as you have a moderately sized sealed enclosure or a PROPERLY designed ported box 400-500W should be no problem for this beast.

I've been running two of these in a sealed enclosure (1cf per sub no fill) with 300W RMS of class AB power. They're as efficient as any subwoofer I've used before, and handle everything down to 20Hz with plenty of control. The haven't struggled with anything I've thrown at them and just sound darn good with all types of music.

The only thing I don't like is the cheesy plastic dust-cap. I liked the old orange JBL logo with the peak wattage stamped proudly in large font. Oh well, nothing is perfect.

Great Amp

I have this amp pushing a soundqubed sdc2.5 12 and it is loud, I connected my four factory speakers and they sound great. I have had this amp for 2 weeks and I haven't had any problems, I highly recommend it!!!!
