Kicker builds the Solo-Baric L7 component subwoofer to deliver state-of-the-art bass. An ultra-rigid cast aluminum basket houses the patented SoloKon™ one-piece square cone to create a speaker that moves lots more air than a comparably sized round sub. The precision-built motor structure won't yield to stress, giving you chest-thumping low end that won't quit when you push your system hard.

The Solo-Baric L7 Series 08SL1274 12" subwoofer features an injection-molded polypropylene cone that works with a tough Santoprene™ rubber surround to dish out monster bass in a sealed or ported enclosure. Its unusual shape and black finish make a strong style statement, and you can add an optional grille to further enhances its looks. This sub packs dual high-temperature 4-ohm voice coils, giving you the flexibility to build a multiple sub setup or to draw more power from your amp with a low-impedance load.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most 2-channel car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation. Most mono amps are stable down to 2 ohms.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

I have 2001 Lincoln LS....i used to have Type R's and my Rockford Fosgate 1500-BD amp was killing those subs....then i got Polk Audio SRC 12's and those blew in 2 weeks then i upgraded to these bad trunk is about to explode...people hear me from 12+ blocks away! no lie....these subs are the best...great sound...and if you like loud loud bass...these are for you...hits the high and lows great! i need to get some dynamat but too be honest...idk if that will help at all....these things are incredible....

Basically my set up = 2 L7 12s and a 2000watt, 4 chan amp. These subs can handle whatever amp you hook them up to. I had to get big amps for my mids and highs just to hear them! These subs have succesfully made my tail light covers fall off, all mirrors cant sit still anymore, and even opens the trunk of my 91 Maxima! Try to turn the bass as low as you can, not that it will matter!!!

as loud as 2 JL audio subs

Written By encryptor, anderson, IN on Saturday, April 18, 2009

had 2 JL Audio w3v3's in sealed enclosures to JL's spec.
just installed this in a sealed q-logic box 1.25 ft.3 and hooked to same amp, its just as loud but not as punchy.

Best sub there is

Written By Nick, Albuquerque, NM on Thursday, September 25, 2008

I had 2 12" Type-Rs in a ported box, and I thought they slammed pretty hard. Good SQ as well, really good response time. Fast double bass in rock sounded nice and clear, not like one muddy boom. And they slammed pretty hard with extended super lowend hits. I powered them with a Kicker ZX750.1 that was tested at 940W RMS.

I replaced them with a single Kicker L7 12" and it absolutely blows them away. If you can afford L7's you won't be dissapointed, they are incredible. All my buddies who have them have blown out their windows, I'm afraid to turn mine up that loud. If you can give them a lot of power they will beat any other sub hands down. At low gain and no bass boost it is so loud it is actually hard to breathe. Not just feel it in your chest bass but can't get enough air bass.

These subs are LOUD. They hit like no other sub I have heard. I have 2 of these powered by a 1000 watt kicker amp. my base is set on -5 (negative 5) and when I turn up my radio only half way up my whole car shakes and my rear view mirror shakes out of position. When I turn my base up and my radio 3/4 of the way my car feels like it is about to shake itself apart. If you are looking for something loud I would highly recommend these. I have heard that square sub's are not as crisp sounding as round ones but that is total bull. These sound better than any other thing I have heard. The only problem with these is that they are almost 2 loud. I have set off car alarms driving by with only half power and my ears hurt when I turn the volume up. Other than that these are some bad speakers

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 (or Sd) for a given size baffle, 16% to 20% more area than a conventional subwoofer. More cone area means the Solo-Baric L7 moves more air, resulting in louder, deeper bass.

Cone Material: The square SoloKon design is a unique one-piece construction, using polypropylene material that moves as a lightweight piston, for improved control. The cone remains rigid, minimizing cone flex and distortion. A rear cone brace integrates into the cone with a continuous contact perimeter weld, which offers unmatched strength and resistance to deformation under pressure.

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, even in the harshest conditions.

Spider: The woofer is equipped with a wide poly-cotton spider which easily handles high cone excursions due to its increased diameter and unique shape.

Enhanced BAM (Basket And Motor) Assembly: The Solo-Baric L7 utilizes a high strength stamped steel basket which features a low-profile open design and provides a solid foundation for the precision-aligned motor assembly. Perimeter venting in the BAM relieves pressure from under the spider, supports linear excursion, and helps dissipate heat from the voice coil and motor structure.

Dual Voice Coil: The dual ultra length voice coils sustain enormous cone excursion and provide flexible impedance matching options. The high-temperature Polyimide Film Voice Coil former improves sonic and conducive properties, and prevents thermal-electrical meltdown. The voice coils are rated to 220° Celsius.

UniPlate Construction: The Solo-Baric L7 features a one-piece UniPlate construction with a vented hyper-extended pole piece and backplate. This unique design provides the following benefits:

  • Optimizes heat transfer efficiency for cooler operation and maximum power handling ability.
  • Eliminates erratic magnetic flux from the voice coil gap.
  • Releases pressure under the suspension for uniform cone movement and responsive low bass.
  • Prevents the voice coil from bottoming out and corresponding damage.

Tinsel Lead Wires: The sleeved, high-power tinsel lead wires eliminate broken leads and power loss, due to the common use of "insufficient-gauge" lead wires. The lead wires are terminated with multiple polymer-based strain-relieving mechanical fasteners.

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.

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

Break-in Period: Due to the complex nature of Kicker Solo-Baric L7 woofers, 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: The power handling specifications differ according to the type and size of the enclosure. The power handling specifications assume that both voice coils are in use. Note: Both voice coils in a dual voice coil speaker should always be connected.

Recommended Sealed Box Volume: When mounted in a sealed enclosure, the woofer delivers massive amounts of high-impact bass and can be driven with punishing levels of amplifier power.

  • Compact (minimum enclosure volume): 0.88 cu/ft; the woofer can handle up to 750 watts RMS (375 watts per voice coil)
  • SQ (maximum enclosure volume): 2.0 cu/ft; the woofer can handle up to 750 watts RMS (375 watts per voice coil)

Recommended Vented Box Volume: The vented enclosures incorporate massive slot-loaded ports with ultra-low air velocity and hard-hitting bass. These are not your traditional port tubes; the slot-loaded ports are integrated into the enclosure design.

  • Compact: 1.75 cu/ft; 2.5" x 13.25" port opening; 22.5" port length; the woofer can handle up to 600 watts RMS (300 watts per voice coil)
  • SPL/Deep Bass: 3.25 cu/ft; 3" x 13.25" port opening; 14.5" port length; the woofer can handle up to 600 watts RMS (300 watts per voice coil)

Note: The power handling specifications listed with the vented enclosure recommendations apply only when a 25Hz, 24dB/octave subsonic filter (sold separately) is used with this woofer. If a subsonic filter is not used, power handling may decrease, excessive port noise can occur, and the life of the woofer may be shortened.

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 11-1/16" x 11-1/16" square opening.
