L7 Technical Manual Kicker Solo-Baric L7-Series Subwoofers Recommended Applications / Version 2.
Features — Mica Filled Polypropylene with a Titanium Deposit Coated Cone An Ultra High Performance look that makes the Solo-Baric® L7 truly a statement piece. The cone gives you deeper and stronger bass at higher listening levels with less distortion due to less tendency to flex. Because, when a woofer cone flexes, there is a loss of output. This loss of output translates into less bass.
FEATURES cont. ä with Vented Hyper-Extended Pole — Blackened One Piece Uniplateä 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 temperature of the voice coil. Note:The increase in temperature increases the impedance of the speaker. This results in lower output and is referred to as Power Compression. 2.
Kicker Solo-Baric L7-Series Subwoofers Recommended Applications Page 4 One-Piece extended Pole, invented by Stillwater Designs, creates a broad, symmetrical magnetic field for superior power handling, precise voice coil control, and minimal deep bass distortion. Rubberized Outer Cover Protects massive magnet structure from chipping or breaking. Perimeter vents Create a vortex cooling effect around the voice coil.
Thank you for your support of Kicker products, and especially our Solo-Baric® L7 (patent pending) square subwoofers. 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.
Sealed Enclosure Applications The Kicker Solo-Baric® SL7 woofers are designed to give more output than an equivalent round speaker. The SL7 is amazing when used in the recommended sealed boxes. These sealed enclosure SQ recommendations will give the smoothest response with the most energy at really low frequencies, around 20 to 30 Hz. The recommended Com pact sealed boxes are in line with our traditional Solo-Baric enclosures.
Characteristics of Sealed Enclosures The most basic and simple of all speaker enclosures is the sealed box or acoustic suspension design. The acoustic suspension design has several advantages; it is easy to build, easy to tune and offers high power handling, tight response and extended low end output. Acoustic suspension enclosures roll off at 12 dB per/octave.

Ported/Vented Enclosure Applications Ported Solo-Barics incorporate massive slot loaded ports with ultra low air velocity for ground pounding street bass that will make your hair stand on end (if you have any left)! These are the enclosures of choice for outrageous street bass and high performance SPL contests. The following chart shows three recommended ported enclosures for each Solo-Baric driver. Compact has increased bass efficiency over a sealed enclosure, yet can still fit in tighter applications.
Characteristics of Vented Enclosures A vented enclosure is not much more complex than a sealed box. It consists, basically, of a box with a hole in it. However, despite its simple design, vented boxes are considerably harder to get good performance from than sealed boxes - although many times the extra effort can be worth it. The vent in the enclosure interacts with the volume of air in the cabinet and the driver to help increase output and reduce cone excursion at and around the tuning frequency.

Box Building & Mounting Hints All the cubic feet numbers given in the supplied charts include the displacement of the woofer. For the ported boxes the displacement of the port must be added to the final design. It will be impractical to use round ports for these designs. The rectangular port information given will yield the best results. Always use 3/4” or thicker MDF and make sure all the joints are secure and well sealed. The peak pressure in a ported box can exceed that of a sealed enclosure.
Box Building & Mounting Hints If you would like to use a vented enclosure, but the box designs we provide you with (in this manual) do not fit because of width or depth, the designs can be modified. The shape of the enclosure is not vital, but The Vol ume Is. The volume, of the design you choose, must stay the same. The following diagrams provide you with some help to insure your enclosure is built correctly.
Box Building & Mounting Hints Here are a couple more examples of the different shape enclosures you can build. The woofer can be mounted on the same side as the port or the back side of the enclosure can be slanted to fit up against your back seat.. On the cut sheets we provide, change the dimensions to accommodate the woofer and the vent on the same side.
Wiring Options The following diagrams are the most popular wiring configurations when using Dual voice coil woofers. They show a typical single channel wiring scheme. Check the amplifier’s owners manual for minimum impedance the amplifier will handle before hooking up the speakers. Remember: 4 Ohm mono is equivalent to 2 Ohm stereo.
