Our take on the Kicker Solo-Baric L7 S12L72 by Crutchfield's Steven Johnson
Kicker "reshaped" the way car audio enthusiasts look at and hear bass with the Solo-Baric L7! The S12L72 12" subwoofer squares off against the competition with a titanium-deposit cone housed in a non-resonant aluminum basket for mindblowing performance. The Santoprene rubber surround guides woofer excursion for extreme accuracy at ultra-high SPL levels.
It's no secret that the woofer cone of the S12L72 is as much as 20 percent larger than 12" round subs that's why this sub is able to pump out major league bass. The dual 2-ohm coil design offers extra wiring flexibility with a compatible amp, and this L7 sub works great in sealed or vented enclosures. Perimeter cooling helps keep voice coils cool so this baby can run hard without distortion. Give your installation some attitude with one of Kicker's cast-aluminum grilles (optional).
Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation.Details:

Dual Voice Coils: For increased system flexibility, the woofer has two 2 ohm voice coils. When the voice coils are wired in parallel with each other, the woofer presents a 1 ohm mono load. When the voice coils are wired in series with each other, the woofer presents an 4 ohm mono load. In addition, each coil may be connected to a different amplifier channel and each channel will see a 2 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 Materials: A titanium deposit impregnated cone is used resulting in greater rigidity for less cone flex and less distortion. In addition, the cone is also very resistant to environmental extremes.
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 surround is stitched to the reinforced cone edge, making separation between them virtually impossible.
Inverted Structural Dome: The Inverted Structural Dome replaces a conventional dustcap and locks into the cone for unmatched structural integrity and greatly reduced cone flexing/resonance.
Cast Aluminum Frame: The cast aluminum frame provides precision alignment and dependable motor structure support.
Spider: The durable resin-impregnated poly-cotton spider provides precise coil alignment and critical cone motion control.
Voice Coil: The multi-layer voice coil and Kapton former create a superior magnetic field and effectively dissipate heat.
One-Piece Extended Pole: The one-piece extended pole creates a broad, symmetrical magnetic field for superior power handling, precise voice coil control, and very low deep bass distortion. Venting in the pole piece eliminates noise and distortion caused by huge amounts of airflow created by cone excursion.
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.
Black Plating: The black plating on the UniPlate and top plate provides maximum heat dissipation for cool operation and extended voice coil life.
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: Front and rear gaskets insure an airtight seal.
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 during installation.
Speaker Terminals: The terminals are spring loaded and nickel-plated for solid connections with large gauge speaker wire.
Enclosure Compatibility: This woofer can provide extended bass in sealed and vented enclosures (please see the "Enclosure Compatibility" section for more information on the recommended enclosures).
Power Handling: The woofer has two 2 ohm voice coils, and each coil can handle up to 375 watts RMS (750 watts peak).
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; each coil can handle up to 375 watts RMS (750 watts peak)
- SQ (maximum enclosure volume): 2.0 cu/ft; each coil can handle up to 375 watts RMS (750 watts peak)
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"x13.25" port opening; 22.5" port depth; each coil can handle up to 375 watts RMS (750 watts peak)
- Street Bass: 2.5 cu/ft; 2.5"x13.25" port opening; 16.5" port depth; each coil can handle up to 375 watts RMS (750 watts peak)
- SPL/Deep Bass: 3.25 cu/ft; 3"x13.25" port opening; 14.5" port depth; each coil can handle up to 375 watts RMS (750 watts peak)
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, the power rating will decrease and excessive port noise can occur.
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 11.146" x 11.146" square opening.
Manual Corrections: The specifications printed in the 2002 manual are preliminary. Per Kicker, some of the specifications have changed and the following is a list of corrections:
- SPL: The manual lists the sensitivity as 86.9dB. The correct sensitivity is 87.4dB.
- Xmax: The manual lists the Xmax as 12.954mm. The correct Xmax is 12.7mm.
