Features

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.

Note

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.
