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 2-ohm voice coils that are wired in series, presenting a 4-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: 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
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
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.
Tinsel Leads: The speaker
features sleeved high-power tinsel lead wires to resist breakage and
power-robbing resistance losses.
The spring posts will accept bare wire and pin connectors.
Sensitivity: In the features and specs
section, the sensitivity is automatically rounded up to 86 dB. The enclosure
actually has a sensitivity rating of 85.6 dB.
- Overall: W=17.563",
H=14.75", D1=10.209", D2=7.959"
- Depth Note: The depth
measurements include the protrusion of the grille on the front, and the
speaker terminals on the back. The enclosure by itself has the following
depth measurements: D1=9.25", D2=6.25".
