yBlackened One Piece Uniplatewith Vented Hyper-Extended Pole

1.Provides enhanced heat transfer for cool operation and maximum power handling. The heat is transferred from the pole piece to the back plate, effectively acting like a radiator in an engine. This lowers the operating tem- perature of the voice coil. Note:The increase in temperature increases the impedance of the speak- er. This results in lower output and is referred to as Power Compression.

2.Reduces non-linear magnetic fields around the voice coil gap for superior cone motion control. The extended pole assures the voice coil is always in the magnetic field when moving peak to peak. When the speaker reaches it’s Xmax, the voice coil is still in the gap between the pole piece and magnet structure due to its extended pole-piece.

3.Releases pressure under ISD for freer cone motion and enhanced low frequency response. Air trapped under the ISD is forced out though the pole-piece to allow the cone to move freely. Heat and pressure build up under the ISD and need to be released to allow the speaker to function properly.

yHigh-Temp Kapton® Voice Coil Former Heat is the primary enemy to the life of a speaker, which is one of the reasons we use Kapton® voice coil formers. Kapton® is a man-made product that is light, durable and heat- resistant. The Kapton® former acts as an insulator to keep the heat of the voice coil from breaking down the adhe- sive that connects the voice coil to the cone. During high excursion and prolonged exposure to heat, the Kapton® former holds its shape and does not expand or contract. As a bonus, Kapton® is also a very quiet material and dur- ing operation, does not discolor the music by adding unwanted sound.

yISD (Inverted Structural Dome) Kicker was one of the first companies to switch to the Inverted Structural Dome. We have designed a cone with a groove for the ISD to lock into, further adding strength to structure. When a cone reaches it’s peak it wants to buckle because it’s momentum keeps it moving out. The ISD provides structur- al support for the cone to resist buckling. NOTE: When the cone buckles, the output of the woofer decreases.

Therefore, the ISD is not just a cosmetic thing, it is an integral part of the woofer to maintain it’s maximum per- formance.

yStitched Surround A signature of KICKER woofers has always been the stitched surround. It prevents the sur- round from separating from the cone at high excursions. When the woofer is moving back and forth it puts a lot of strain on the adhesive that is holding the surround to the cone and often causes the two to separate. Stitching the surround to the cone eliminates this from happening. If stitching were inexpensive, everybody would do it!

yDual Ultra-Length Voice Coils A speaker can obtain extreme Xmax only when the voice coil is long enough and can sustain the stress. Dual voice coils give the installer the option of several different wiring configurations compatible with any amplifier. In addition, the S15L7 has Dual spiders to help control the massive structure!

ySleeved High-Power Tinsel Lead Wires Resist lead breakage and power robbing resistance losses under demanding conditions. When a speaker is being pushed to it’s limits there is a lot of strain being put on the leads, especially on high performance woofers like the Solo-Baric® L7. Sleeving tinsel leads help strengthen them to resist breakage.

ySpring-Loaded Nickel Plated Terminals On a High Performance speaker like the Solo-Baric® L7, you would expect nothing less than a High Performance terminal. They allow the installer to use the maximum gauge wire to minimize power losses for the ultimate Ground Poundin’ system.

L7 specifications

The Kicker L7 series is renowned in the world of car audio for delivering impressive bass and unmatched performance. Known for its square design, which maximizes cone area, the L7 subwoofers are engineered to push the limits of sound quality and output. One of the standout features of the Kicker L7 is its unique Solo-Kon technology, which incorporates a square cone shape to deliver more surface area than traditional round subwoofers, resulting in deeper bass and higher sound pressure levels.

These subwoofers are crafted from high-quality materials, ensuring durability and consistent performance. The injection-molded cone is lightweight yet incredibly strong, paired with strong reinforced ribs that help to support the cone during high excursions. This combination minimizes distortion and provides a clear, powerful bass experience. The subwoofers also come equipped with a strong motor structure, which ensures precise control over the cone movement even at high volumes.

In terms of power handling, the Kicker L7 subwoofers excel with their ability to handle significant wattage. They often feature dual voice coils, providing flexibility in wiring configurations, and making it easier to achieve the desired impedance for optimal performance in any system. This ability to handle high power input translates into an impressive output level, making the L7 a favorite choice among serious audio enthusiasts.

The Kicker L7 subwoofers also integrate advanced cooling technologies, such as a vented pole piece and perimeter venting, which help dissipate heat during prolonged use. This ensures reliability and longevity, reducing the risk of thermal failure – a common issue with many high-performance audio components.

Additionally, the Kicker L7 subwoofers are designed for customizable installation, allowing car audio enthusiasts to build their systems according to specific needs. With a variety of sizes available, including 12-inch and 15-inch models, users can easily find the perfect fit for their vehicle and audio system.

Overall, the Kicker L7 series stands out for its innovative design, superior construction, and penchant for delivering powerful, deep bass that bass enthusiasts crave, making it a cornerstone in the realm of car audio. Whether you are looking to enhance your daily drive or bolster your sound system for competitive use, the Kicker L7 delivers uncompromising quality and performance.
