Our take on the Kicker Solo-Baric L7 Series 06S12L74

Kicker's Solo-Baric L7 subwoofers deliver gutbusting performance that will separate your system from the rest of the pack. And you'll appreciate the dual voice coil design that allows you to wire your sub to get the most out of your system.

Kicker's Solo-Baric L7 subwoofers deliver gutbusting performance that will separate your system from the rest of the pack. And you'll appreciate the dual voice coil design that allows you to wire your sub to get the most out of your system.

The 06S12L74 12" subwoofer begins with a square cone crafted from aluminum-treated composites and suspended in a tough Santoprene rubber surround. This combination of an ultra-rigid cone and excellent cone excursion moves lots of air, for bass you can hear and feel.

It takes more than a cone to make a great sub, and Kicker's got the whole package. A cast-aluminum basket minimizes resonance that affects accuracy at higher levels, while Kicker's UniPlate construction virtually eliminates "bottoming out" — the evil sound that a sub makes when it's overextended.

Perimeter cooling vents help the L7 sub run hard and long without distortion. This versatile sub works great in a sealed or vented box — whether you prefer tight, punchy bass or big, booming bottom, the Solo-Baric L7 subwoofer delivers.

Kicker l7 12 inch

Austin from Ashland ky on 12/8/2012

I have a jeep cherokee, and my buddy gave me a 12 inch kicker l7 in a ported box for free. Its the older model l7. I hooked it up to a crappy 1000 watt sony xplod amp, and it pounds! The amp would be lucky to be pushing 800 watts. But this sub is rediculous! I would recomend it to anyone who is crazy about there bass. It flexes my roof, windows, door and shakes the whole car

Pros: Tremendous bass, good build, awsome looking, heard from blocks away

Cons: The price is rediculous.

These are great

Pure Awesome

Jwizzle from Corpus Christi Tx 78413 on 6/18/2012

1 12 is all you need for killa goat bass!!

Pros: Durable build, good easy installer friendly voice coil connects, well vented design basket to cool off the coils, nice 1 piece construction cone, good excursion, square design maximizes cone area to move more air than typical design

Cons: Every body runs for cover before you come down the street

Does Crutchfield Sell

Lukk from Grayling, Michigan on 5/10/2008

Crutchfield Customer Review (What's this?)

This sub pounds!!! (Hence the reason for the title) I built my own 3.0 cubic foot enclosure, and after "port trial and error", meaning I started off with a single 4" lightning audio aero port 16" long, and was advised a slot port would work better. After installing the new port, I threw some tribal art work on the enclosure, and re-installed it in my truck(today). The sub is driven by a Kicker ZX750.1 (07 model), and it tickles my soul to see the fogies give me dirty looks, and the "me" generation roll their windows down and give a thumbs up! A neighbor 600 yards down the highway can hear me pull in my driveway(From inside his house). NUFF SAID!!! Livin' LOUD!!!!!!!



Kicker L7

hogfarmer07 from Northeast, Missouri on 2/14/2008

I purchased a pair of these subs brand new a year ago. I have them hooked up to a Kicker KX1250.1 mono amp pushing 1,318 watts. This thing is loud! The bass is deep and the sound quality remains intact. I did however notice that it does make a big difference if you let the sub break in moderately for about 2 weeks. I would highly recommend this sub to anyone who is serious about car audio.

I ordered this sub about 3 months ago and finaly hooked it up.It sounds awesome.Im running it in a 1.75sqf ported box with a alpine m850 amp.Great sub and worth the money




bigwil707 from Eureka, Cal. on 8/14/2007

I have one of these sub in a kicker made ported box in my land rover, with a kicker zx750.1 amp, and they are a perfect match. It's soooo loud, but still keeps great sound qualty. For the price there is nothin' better. &quot;livin' loud&quot;<BR>p.s. Must allow for 20 plus good hour of warm up or the sub WILL blow.

livin loud

potaru01 from Austin,TX on 4/21/2007

Give this sub a true 750 watts rms put it in a box that lets it breath then let it break in, and enjoy urself one of the best subs out and not just for the price hits real low when it needs too and quick, the bass is very tight. Only reason i gave it a 4 is because it cant be perfect




dale from maine on 2/28/2007

i have one of these in a q-logic 1.75 cube ported enclosure. im runnin an mtx tc8001 to it.<BR>so far im really pleased. havin a hard time keepin the volume down during break-in as i know this bad boy is gonna pound like the devil. this is my first system desighned around a single sub....i think im gonna be happy.




fred from syracuse ny on 1/10/2007

the 12 inch L7 is agood sub but isold my 2 L7's and bought 2 15 type r's they are a lot better sub. my amp is a hifonics brutus 1206dx super class d and it is producing about 1800 watts at 1 ohm. the tpye r's like it better than the L7's did



Head-rattlin' bass

Lord of Bass from Lake Worth, Fl on 9/7/2006

I have two of these hooked up to a Kicker ZX1500.1 and all I can say is "Wow!". These subs pound. I originally had L5's and a ZX1000.1, but these L7's are so much better. My HOOD rattles and I Dynamtted the whole car! The ZX1500.1 is a perfect match and I don't have to turn the gain up past halfway. BREAK THESE IN!! I did mine with a 50 amp DC converter power amplifier, a Kicker amp, and a cd player with a 40hz test sound run on a loop for about 10 hours in my living room. The bass is so full and accurate, people talk about Infinity Kappa's and MTX but L7's are king.




J from Columbus, Oh on 7/26/2006

I bought 2 of these when you only need 1. the worst part about these subs is waiting the 2 weeks to break them in. Once broken in BOOM, i only have 1000 watt kicker amp running them and i cant take the volume past 15 and the bass knob half way before my head hurts and all my mirrors have moved. if you can afford them and patient enough to wait the break in time def a great buy.




corvettecoop from Woodbury, MN on 6/19/2006

I have had this installed in my Blazer for almost a month now and I have never herd any system that comes even close. I have a single 12" in a slotted 2.8 cubic foot enclosure. Powered by a ZX750.1. This sub pounds so hard. I have never had so much flex in my body. The rear window flexes almost .75" out. I recently blew by buddy's Monte Carlo out of the water with his 3 10" MTX and 2000W Audiobahn amp he wasn't able to touch the capabilities of my set up. This sub sounds great and has a lot of potential. As long as you are sure to break in the sub properly you will have no problem setting off every car alarm within earshot.




MILLER from WASHINGTON, DC on 5/16/2006

SO SICK... AND ONLY 12 INCHES... May 16, 2006 <BR>First off let state the I own last years Version... This I have this Sub paired up with the Kicker KX600.1 Mono Amp along with a Custom Kicker Ported Box made specially for this Sub and it Flat Out Bangs!!! No lie I work at a Nation Retailer that sells Rockford Infinty Pioneer and so forth and trust me my one L7 crushes all 12's including most if not all 15's. And were not just talkin SPL but SQ as well. But it to this you must feed it, its power hungry... Not only does kicker know bass but they know quality as well its been over a year and not a single problem and they still Bangs like a Champ. <BR> <BR>If you must know I have this Set-up running off the Kicker KX600.1 Mono Amp wired with the Rockford 4 Gauge Kit with the Twisted Interconnectors/RCA's and its pure madness in my Deville. Those who know about Kickers Amp Know they are underrated so instead of 600 Watts @ 2 OHMS I'm running 740 Watts @ 2 OHMS and it matches the L712 perfect because its only 10 Watts off the RMS but it can handle more than 750 Watts. This is great system and you won't be disappointed. BTW Please Allow 2-3 Weeks for the Subwoofer to break in properly and invest in Dynamat and a Capacitor because you will need it!!! <BR>



Kicker Solo-Baric L7 Series 06S12L74

Blake from Turtle Lake, ND on 5/13/2006

I bought two of these, they sound absolutely awesome. I have a freind with two 12 inch eclipses, and he can't touch the sound i can make. Im running them with a 1200.1 kicker amp, which is just barely enough power to meet the RMS on each sub. One peice of advice though, make sure your box is big enough, i had a box that was too small, and i only added 1 cubic foot to it and it made such a world of difference its just crazy. These subs are an awesome way to make your car heard from blocks away!



Optimized Performance

Issac from Hilo, Hawaii on 5/3/2006

I had bought one of these subs just to see if it lives up to its spec and WOW! I am VERY impressed on how Kicker had developed its products. I am running a 750w RMS Kicker amp with it and it shakes everything around you. Very Important: Break in your sub before slammin' the #%*@ out of it. Excellent choice for quality over quantity.



its not a fluke its your amp and box

bigben210tx from sa town on 4/23/2006

steedamike dont i repeat dont get advice from local mom and pop shops they dont know what they're talking about to power a L7 properly your gonna need atleast 800watts of clean power. and as for the box .8 cubes is about 2 cubes to small you need at least 2.5 cubes to make a L7 sound good. <BR>as for a review for this sub its a great sub sounds decent and with the right installation and power can be very loud. the onl thing i can see that is bad about L7s is when the say dont put 1500 watts to the sub they mean it DONT or you will have a blown sub. also if your on a budget go get a alpine type r 12 it can get as loud as a L7 and sounds alot better.<BR>peace



Big Headache

Anonymous from Santa Rosa, CA on 3/15/2006

I bought one of this sub L7 an WOW!! it really shakes things up!! 20min.. drivin an gave me a headache wit all that BASS. my only problem is that my car might fall apart. great sub!<BR><BR>I have my sub in a big box.. wit a alphine amp..1000Watts



Be careful

Justin from Arkansas City, KS on 3/14/2006

I have had this sub for only 1 1/2 weeks and I blew it. You must heed the warning. Breakin these subs or they will BLOW. the manual says at least 20hrs at low volume this is very important. Do this and I think you will be happy with the nice bass, and power handleing.



hope its a fluke

steedamike from douglasville, ga. on 3/12/2006

i bought one of these and had it professionally installed in a .8 cft sealed enclosure. i had it on an amp that put out 400 watts rms x1 and after about 2 weeks (when it got broken in), it developed a motor noise (sounded like bottoming out) when it hit low notes at high volumes. i exchanged it for another one and the same thing happened




Hands-on research

Product Research

Enclosure Compatibility


Dual Voice Coils: For increased system flexibility, the woofer has two 4 ohm voice coils. When the voice coils are wired in parallel, the woofer presents a 2 ohm load. When the voice coils are wired in series, the woofer presents an 8 ohm load. In addition, each coil may be connected to a different amplifier channel and each channel will see a 4 ohm load.

Square Design: By making the Solo-Baric square, Kicker is giving you the most possible cone area (Sd) for a given size baffle, 16% to 20% more area than a conventional round subwoofer. More cone area means the Solo-Baric L7 moves more air, resulting in louder, deeper bass.

Cone Materials: An injection molded and reinforced, one-piece SoloKon cone is used resulting in greater rigidity for less cone flex and less distortion. In addition, the cone is very resistant to environmental extremes. A rear cone brace provides added strength and reduces cone flex under stress.

Surround: The tough, flexible Santoprene rubber surround has a long-throw, positive-roll design, which controls extreme cone excursion and is highly tear-resistant. The corners of the surround are ribbed to ensure linear cone motion. The surround is stitched to the reinforced cone edge, making separation between them virtually impossible.

Inverted Structural Dome: The Inverted Structural Dome replaces a conventional dust cap and locks into the cone for unmatched structural integrity and greatly reduced cone flexing/resonance.

Patented Enhanced BAM (Basket And Motor) Assembly: The cast aluminum basket features a low profile, open design to provide a solid anti-resonant foundation for the motor assembly.

Spider: The durable poly-cotton semi-progressive spider provides precise coil alignment and critical cone motion control.

Voice Coil: The voice coil is wound around an aluminum former with a flared bottom to effectively dissipate heat. The result is a 220° Celsius (428° Fahrenheit) rating to increase durability.

Chromed UniPlate Construction: The UniPlate construction combines the backplate and extended pole piece into a single unit to maximize magnetic efficiency and minimize alignment problems often caused by two-piece construction. The bottom of the UniPlate is chromed to provide enhanced heat transfer for cool operation and maximum power handling.

Bumped Back Plate: The deep bumped back plate lets the voice coil reach maximum excursion without bottoming-out.

Perimeter Venting: The perimeter venting cooling system continuously pumps hot air away from the voice coil, replacing it with cool outside air.

Gaskets: The one-piece rear gasket insures an airtight seal. The shielding front gasket enhances the cosmetics and helps protect the wide surround.

Rubber Magnet Boot: A black rubber boot covers the outside edge of the magnet structure to improve the cosmetics of the woofer and protect the magnet from chipping or breaking during installation.

Tinsel Leads: The tinsel lead wires are silver coated flat braided ribbon cables with soft rubber jackets. They are glued and stitched to the spider and the connections are offset at the terminal to align with the cone brace indentation and support extended excursion.

Speaker Terminals: The terminals are spring loaded and nickel-plated for solid connections with speaker wire up to 11 gauge.

Break-in Period: Due to the complex nature of Kicker Solo-Baric L7 speakers, they require a break-in period in order to produce optimum low-bass response. The high-performance suspension system makes the speakers very stiff "out-of-the-box". Approximately 2 weeks of daily playing will allow the suspension to break-in and reach its optimum equilibrium. A "broken-in" subwoofer will exhibit stronger bass performance, smoother response, and greater low-bass extension.

Enclosure Compatibility

Power Handling: Power handling varies depending upon the enclosure, as listed below. The power handling specifications listed with the vented enclosure recommendations apply only when a 25Hz, 24dB/octave subsonic filter is used with this woofer; if no subsonic filter is used, the power rating will decrease and excessive port noise can occur.

Recommended Sealed Box Volume:

  • Compact (minimum enclosure volume): 0.88 cu/ft; the woofer can handle up to 750 watts RMS
  • SQ (maximum enclosure volume): 2.0 cu/ft; the woofer can handle up to 750 watts RMS

Recommended Vented Box Volume:

  • Compact: 1.75 cu/ft; 2.5" x 13.25" port opening; 22.5" port depth; the woofer can handle up to 600 watts RMS
  • SPL/Deep Bass: 3.25 cu/ft; 3" x 13.25" port opening; 14.5" port depth; the woofer can handle up to 600 watts RMS

Cutout: The woofer will not mount in a standard enclosure with a round cutout. Instead, the woofer must be mounted in an enclosure with a 11.25" x 11.25" square opening.
