Thank you for your support of Kicker products, and especially our Solo-Baric® L7 (patent pending) square sub- woofers. The SL7s are truly unique products in a world of round subwoofers. Our technical and R&D staffs have designed some extreme enclosures beyond the small sealed boxes Solo-Barics are famous for. They have unleashed the awesome capabilities of the L7s.

In this paper we will explore some applications for the Solo-Baric® L7 complete with box drawings and cut sheets plus some important information regarding the break-in period for this ground-breaking speaker.

Important Break-In Information

Due to the complex nature of the Solo-Baric® L7s they require a little extra time to break-in. Especially in sealed enclosures, break-in is a must in order for woofers to produce optimum low bass response. Due to the high per- formance suspension system incorporated in the Solo-Barics they are very stiff “out of the box”. Approximately two weeks of daily playing will allow the suspension to break-in and reach its optimum equilibrium. The “broken-in“ sub will exhibit stronger bass performance, smoother response, and greater low bass extension.

For those of you with more sophisticated audio equipment, the Solo-Barics can be broken-in on the test bench overnight with the following procedure.

Solo-Baric Freeair Break-in Procedure

1.Connect the speaker to a power amp of about fifty watts or more. The speaker should not be mounted in any enclosure - just freeair. Please make sure it will not walk off the bench while it is playing!

2.Connect an audio generator to the input of the power amp, and adjust the generator to approximately 45Hz for the S8L7, 35 Hz for the S10L7, 30 Hz for the S12L7, and 20 Hz for the S15L7.

3.Now adjust the gain on the amplifier and generator so that the cone is moving to Xmax. This can be determined visually by looking at the “blur depth” of the logo on the ISD. A close approximation will do. On the S8L7 this will be about 3/4”, on the S10L7 about 1”, on the S12L7 about 1”, and on the S15L7 about 1 1/4”.

NOTE: Keep in mind that as the speaker is used under normal conditions the break-in will continue, so if you don’t have time for the complete break-in period the speaker will still break-in itself under normal usage.

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.
