Enclosure: The enclosure is
constructed from non-resonant 3/4" Medium Density Fiberboard (MDF) and protected
by a layer of rugged catalyzed polyurethane.
Dual Voice Coils: The woofer
has two 4-ohm voice coils that are wired in parallel, presenting a 2-ohm mono
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
Cone Materials: 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.
Spider: The woofer is equipped with a wide poly-cotton spider which
easily handles high cone excursions due to its increased diameter and unique
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
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.
The spring posts will accept bare wire, banana plugs, dual banana plugs, and pin connectors.
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.
Sensitivity: In the Features and Specs
section, the sensitivity is automatically rounded up to 87 dB. The enclosure
actually has a sensitivity rating of 86.8 dB.
