No waaaaaay

So I got this specific sub in a JBL preloaded enclosure (JBL P1220). Absolutely ridiculously loud. Giving it 600W RMS at 2ohms off of a Pioneer Premier D1200M. Sound quality is sick. Amp is pushing it pretty crazy. I think that this could easily be mistaken for 2 12" subs. My deck only has 2.2V outputs so I could be pushing this way harder, and my gain is set pretty conservatively. When I add a little bass boost on my amps remote it pounds harder then I would ever need. Lots of pressure. I recommend getting the P1220 if you can find it which is this sub in a sick big ol' awesome looking ported box. Be careful with this sub, bass this loud can't be good for hearing.

This sub is a tank

Since receiving this sub from Sonic 6 months ago, I've been beating it within an inch of its life, and it's a tank by all means. It hits very hard and digs way down low. We're talking 20 hz low. I played a 20 hz test tone, and I thought my trunk lid was going to give. Seriously, this single 12 inch sub makes my wipers bounce on the windshield. I'm guessing it's hitting every bit of 138 dbs. Not bad from a single 12 in a super low tuned box. I'm a SQ guy, but there's no way to avoid praising the output of this thing. I feel silly bragging about my trunk lid violently trying to give, but I digress. This sub also makes bass a plenty at lower volumes for lower listening levels. I'm impressed.

I have a Boston Acoustics GTA-1000m (also from Sonic) pushing it with around 750 watts RMS by my calculations, as the coils wired in parallel test at 2.5 ohms, not 2 ohms. Definitely take that into consideration when setting gains with a digital multimeter.

It's in a 2.5 net cubic feet box tuned to 25 hz with lots of port area for SQ, output, and super low bass extention. I have since concluded that I built my box too big by about a .25 - .5 cubic feet margin, as it bottoms out a little above tuning before the port begins to decrease the excursion. I would blame that on the fact that it's overpowered, but I know boxes, and that's more of a factor in this problem than the power, as it takes the power quite well for a good while.

However, with that said, I've bottomed it out and had the coils stinky more times than I can count, and it continually delivers up the SQ and the immense output. And, speaking of its SQ, it's hands down the best SQ from any subwoofer that I've experienced personally. I want to hear all the little nuisances with drums and bass guitar, and I get it for sure. No mud, just powerful reproduction of the recording. And, of course, throw in some Bass Mekanik or rap or whatever, and you have flexing car panels all over.

The only downside of this sub is the big, funky basket. It measures 14 5/8 inches across, yet has a typical cutout measurement for a 12. So, good luck finding a prefab for this thing. And, it sticks out of the box by 2 inches. The cone is exceptionally awesome looking Kevlar impregnated paper though. That may be why it's so efficient at lower power levels.

Nonetheless, this product ended my incessant search for an all around excellent performing subwoofer. Get one (or 2!!) while they can be had. JBL out did themselves with this one.

Holy Cow

I've used a lot of subs in the past, high dollar ones and cheap ones alike. This is solid quality right here. Pictures do not do it justice, it is BIG and the motor assembly is HEAVY. It's larger and heavier than my old RE SX12's which were twice the price. It will fit most standard 12" cutouts (11 1/16 inch is not that uncommon), but make sure your box can accommodate its 14 5/8" frame, many prefab boxes won't.

I tossed two of these monsters into two custom 2.5cf ported enclosures tuned to 35hz. Because they are so big, the outer ring blocks a small portion of the port, so I have no idea what that's doing to the tuning. Nonetheless it is loud and the clarity rivals some of the best I've heard. Amp is a HiFonics BXI1608D, rated at 1600 x 1 @ 1 ohm, so conceivably each woofer should be getting 800W RMS each.

I'd stick with JBL's recommended enclosures, I get the feeling mine are a little too large, and that these may have more potential in a smaller box. They are plenty loud enough that I'm probably going to ditch the ported boxes and go sealed to free up some trunk space and get a flatter frequency response.

Buy these, they are practically being given away at this price.

JBL subs

i had two of these in my blazer ran off a lanzar opti drive 1400d and this setup got really loud and i had the subs in a 5.0 cubic foot box^3 tuned to 34hz and i would have to say it was the best sounding system i have ever owned

Great Great Sub!!!

This sub is a beast for a mid-priced sub. I love it, Sounds very clean. What ever you listen to this sub will do the job weather its Rap, rock, Metal, Drun' Bass, Classic Rock they all sound fantastic. I have one in my 2001 S10 Pickup Ext Cab running off a Kenwood KAC-9104D Mono amp. I def would recommend the JBL P1224 to anyone. Just make sure you get a box that fits this subs diameter.... The outer frame is 14 5/8" so plan ahead on that, What a BEAST.

Everything I thought it would be

I got this sub because I once upon a time had a much older model that I liked. This definitely doesn't disappoint either. It's very solid and quality constructed. Much heavier than I thought it would be too. I put this in a 1.75 cubic foot ported box according to JBL's recommendations and paired it with the JBL MS-A5001 amp and it's loud, clean, and accurate. I threw everything I had at it from metal to hip hop and it all sounded great. It's no dub 7, but it is a fraction of the price including the materials cost to custom build the box. One additional note to the durability of this sub. The box this came in looked like Ace Ventura delivered it. As badly damaged as the box was I was almost sure it was broken, but it definitely wasn't.

Great buy!

I LOVE THIS WOOFER!!!! it plays both mids and lows very well and hits precise, it took a while to get broken in but now it's so clean! I'm currently powering it with a kicker zx300.1, it gets the job done but this is a power hungry sub and will need quite a bit more to reach it's potential...

P1224

These don't fit in any prefab boxes out there, so plan on making your own. The specs JBL gives for a box are extremely conservative, like you can put double RMS and not worry about bottoming out, but you can get a much nicer sounding box if you went for a larger port. They sound great and get loud and take their power well

Over The Top

With the large outer ring I had a problem finding a quality enclosure for this sub so I had one custom made for it. While that was quite expensive, it is a perfect enclosure for this speaker. That means that the speaker is going to sound at it's best. With a GTO 7001 connected and the sub set at 2 ohms, this single 12" sub woofer hits harder than Bruce Lee. Well, maybe not that hard but pretty hard. At low volume it still produces that great low end that grabs you by the poo poo and makes you sit up and listen. There is a beast in my trunk and it's name is JBL!

Great Sub

I have 8 of these subs in a explorer sport with only 3200 watts to them and the pressure is unreal. Could push so much more power and not even think twice about it. This sub is a monster. Great sub

(:

I fried my sub so my friend let me use his.

It was this particular sub in a ported pre-fab box, seeing about 650 watts from my Hifonics 2010D

I have to say i am extremely impressed by it's performance, especially for being in a pre-fab ported enclosure; it retained good sound quality. By the time my friend was finished with it, it was well worn in already obviously.

I like loud systems and this definitely did the job for cruising around with some loud bass daily, virtually no distortion, even when you crank it full tilt.

Considering buying two for myself to replace an audioque hdc315 on 2000rms

Awesome

I had one of these in a ported box, and it was freaking loud. I had it in a 2002 Eclipse and it made the back window bow out when it hit. I had it hooked up to a 2000 watt class d precision power amp, that was a great set up.

Best

This product is the best I have used.

you cant get anything better for the price!

I have a set in a 96 Z28 Camaro. They will make your site go blurry, they shake the ground around you. EVERYONE will turn their heads! I do recommend using the grand touring series 1200watt amp with them. Hook them up in line, in series.

p1224 jbl sub

This is a very clean, hard hittin, super sounding sub. I would definitely recommend anyone to buy this over any other sub out there, in this price range. Thumbs wayyyyyyy up!!!!!!

JBL

Big heavy monsters.. they love to hit low low low.. custom box needed.. most prefab boxes wont work with these.. you need a super strong box as well or you will rip cheap boxes apart.. they are optimized in sealed boxes.. but if you listen to mixture of rock and pop.. run ported.. tuned to 34hz to factory TS parm's for box size.. been running 2 of these for 3 years.. over powered and still banging like new.. I can't seem to blow them..
