Got enough juice? Get an amp for your new sub Kicker Solo-Baric L7 subwoofers have a look and a sound that is sure to set your system apart from the pack. The unique square shape demands that you take immediate notice of the S10L74 10" subwoofer, and an aluminum-treated cone with a thick Santoprene rubber surround handles the kind of power that guarantees you'll be livin' loud.

And this sub is loaded with extras that have made Kicker such a dominant name in bass. An enhanced cast-aluminum basket minimizes resonance from the motor assembly, while a rear cone brace controls flexing that can impair sound quality. Perimeter cooling helps it run hard and long without distortion, and the dual 4-ohm coil design offers extra wiring flexibility.

While the original Solo-Baric is recognized as the first small sealed box woofer, this L7 sub is more versatile — it works great in a sealed or vented box. So whether you prefer your bass tight and punchy, gutbusting, or just way down low, this subwoofer delivers.

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.

Priced per speaker

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.

Livin Loud

This thing hurts

Written By BIGGS, Jersey City, NJ on Tuesday, May 17, 2005

I just bought this L7 powered with a directed 1500d and this thing hits at a little less than half way up. It definately surprised me being that it is only a 10 inch sub.

Unbelievable Sound

Written By surfnat3mbps, Luray, VA 22835 on Monday, May 16, 2005

These subs are exceptional, I recently purchased 2 for my Jeep Grand Cherokee, surprisingly enough; 1 would have been more than enough. The sound quality is great and it was really easy to install because it was pre-inserted into it's enclosure. This is a GREAT buy.

holy crap

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 (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: An aluminum 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. 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 dustcap 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 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.

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 front beauty ring and separate one-piece rear gasket insure an airtight seal and provide enhanced cosmetics.

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 speaker features sleeved high-power tinsel lead wires to resist breakage and power-robbing resistance losses.

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: When the subwoofer is mounted in a sealed enclosure that has a volume from 0.66 cu/ft to 1.0 cu/ft, the woofer can handle up to 600 watts RMS. When the woofer is mounted in a vented enclosure, its power handling varies depending upon the size of the enclosure. In a 1.25 cu/ft vented enclosure, the woofer can handle up to 500 watts RMS. In a 1.75 cu/ft vented enclosure, the woofer can handle up to 525 watts RMS. In a 2.25 cu/ft vented enclosure, the woofer can handle up to 550 watts RMS.

Recommended Sealed Box Volume:

  • Compact (minimum enclosure volume): 0.66 cu/ft; the woofer can handle up to 600 watts RMS
  • SQ (maximum enclosure volume): 1.0 cu/ft; the woofer can handle up to 600 watts RMS

Recommended Vented Box Volume:

  • Compact: 1.25 cu/ft; 2.5" x 11.25" port opening; 19.75" port depth; the woofer can handle up to 500 watts RMS
  • Street Bass: 1.75 cu/ft; 2.75" x 11.25" port opening; 17.75" port depth; the woofer can handle up to 525 watts RMS
  • SPL/Deep Bass: 2.25 cu/ft; 3" x 11.25" port opening; 18" port depth; the woofer can handle up to 550 watts RMS

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 9.5" x 9.5" square opening.


Manual Note: The specifications printed in the manual are for the 2 ohm model. The 4 ohm model specifications in the Crutchfield database were obtained directly from Kicker.
