JL Audio 12W7-3

W7 subwoofer

I bought 2 of these in a sealed box that sells here at sonic. I have a fosgate amp pushing around 1800 watts (supposed to be 1900 but being realistic). They are heavy and durabile as a tank! One thing i wanted to point out is these are loud in sealed but you want a ported box if you want windows to blow out. These in sealed boxes need alot of power. I have 2 optima batteries,a 2 farad cap, and a 270amp DC power alternator. It still wants more power! Im gona switch to ported custom box because i heard some W6s that were as loud or louder than mine on 1000 watts,stock alternator and a 50$ battery (come on im mad cuz i spent alot and expected more) once i get them in ported custom box il write another review. These are the best overall subs you can buy bar none! I dont care what anyone says for SQ,SPL, and range these are the king! JUST MAKE SURE TO PUT THEM IN PORTED BOXES OR YOU MIGHT BE DISSAPOINTED?

Best sub ever

Great products, good customer service. Very pleased overall. I will def shop this site many more times.

Oh My Bass

A lot of people say that JL Audio is overpriced, and it kind of is, but we all know that good things don't come cheap. I got this sub to replace my W3's and DAMN, this thing pounds. It handles whatever you throw at it. Lows, highs, anything. You can not only hear the bass, but you can feel it too. If you say that JL sucks or whatever, then why do you think they still get top dollar for this dub7? Or any other sub made by them.. It's the quality. And I pushed my W3's to the max and slapped the hell out of them and they never gave up on me. Never smelt a burnt coil or anything. JL Audio is quality, you get what you pay for.

Update on W7

I had my box made for 2 jlW7s by Fatbox USA. They did a great job and my SPL went way up. I drive a Tahoe, now that I have a ported box the dash actually jumps up and down lol. I dynamited my truck with the NVX sound dampener and it worked awesome! I'm putting realistically 900watts to ea W7 and they love it! If the subs were cheaper I'd build a wall for 6 of these pigs and do second skin application. Be advised you will need a powerful 4ch amp to drive your surround speakers. I have 2 sets of JLC5-650 components and 2 sets of Focal PC690 6x9s to keep up when the bass is cranking. These are great OVERALL subs, if you want big sloppy sounding SPL go buy Kickers,Sundown,DC audio,earthquake ect. If you want pure clean bass you can tweak to your taste, go buy a W7 and get a custom vented box. I promise you won't be disappointed folks!

W7 quality

This sub is made with quality parts and design. JL holds a lot of trusted patents. All the JL audio haters are just more in love with loud sloppy bass. Put this in a vented enclosure around 35hz and 800-1200 watts rms apiece and you cant ask for much better. Install design is #1 with most all JL products.A bad design and you wont get the most out of it. Im talking the kind of car you have,the box size, Dynamat ect. The thing slams and sounds great doing it! If your into SPL competitions yea, this may not be for you? Never think that this thing cant get down with the others though! Its my centerpiece of a $5000 audio system. All JL audio except a rockford Fosgate T1500.1bdcp amp. The $h1t sounds amazing and near life changing experience! Yea sounds crazy but if you love car audio, buy JL.

Best in the business!!!

Great Value

Excellent customer service. Fast shipping! Trustworthy! I definitely will recommend this website to friends & family members. Thank You very much (S.E.) for great deals on the sound system (JL Audio12w7ae & amps, etc..) I'd ordered.

Only the Best

I heard of this beast for years and i finally got up and got one. Wow is all i can say, this thing hits like no other sub. The SPL is intense while it still maintains incredible SQ. This thing is a beast!

JL for life!

I thought I was impressed with the JL 12W6 until it crapped out (due to the eq curve that I didn't know about because it was purchased used.) My plan was to reuse the ported enclosure for the 12W7 but the woofer is damn near larger than the enclosure so I had no choice but to have an enclosure built to specs. There's a note that accompanies the woofer that says to tune your system without an eq curve (had I know that, my 12W6 may still be alive) The SQ of this woofer is excellent yet the 12W7 has SPL like multipe woofers. A ported enclosure is the only way to maximize the performance of this woofer. I have the JL HD 600/4 on my interior speakers and I'm pairing the woofer with the JL HD 750/1 and it's a match made in audio heaven. I have two blue top Optima's without any capacitors (capacitors are worthless) and the amps have no problems getting the power they need even with the ignition being in the accessory only position.

an expensive master peice

i heard these in the audio store and after 5 seconds of hearing my head was hurting and i felt the sub push the air in my lungs.I would get this sub but the obstacle is the money.
