Kicker Solo-Baric L7 Series 08S12L74
12" subwoofer with dual 4-ohm voice coils
Our take on the Kicker Solo-Baric L7 Series 08S12L74 by Crutchfield's Dominic DeVito
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.
Priced per speaker
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.

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.
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.
