Kicker Solo-Baric L7 Subwoofers

The Kicker Solo-Baric L7 woofers continue to be the best sub in their class. The patented square-woofer technology allows for 18% more cone, which translates to more bang for your buck compared to competing round subwoofers. All new for the 2011 series is a redesigned and improved SoloKon cone. The new beautiful look was inspired by the big brother SoloX series, and it's making everyone at Sonic go crazy as it's tougher looking and better-performing.

In addition to the SoloKon improvements, the new L7 woofers also provide a much easier installation. The solid pole piece allows more heat sink capabilities and perimeter venting is built into the spider landing unlike previous years. This also allows for a shallower installation as you no longer have to account for venting through the back of the magnet. To make things even easier on the installer, Kicker moved the binding post to the corners of the woofer allowing for an easier connection when running the subs in parallel or series.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Solo-Baric L7 (Kicker)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
8"
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
900 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
450 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Dual
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
2 ohms
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
28 - 100 Hz
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
82.4 dB
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
12.2 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Square
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Black
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Titanium Deposit Impregnated Cone w/ Rolled Outer Edge
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Santoprene Rubber
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
Optional (Accessory required and sold separately)
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / Vented
Sealed
Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.5 cubic feet
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.5 cubic feet
Minimum Ported Box Volume
This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.66 cubic feet
Maximum Ported Box Volume
This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.75 cubic feet
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
4-3/4"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
7-1/4""
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

I love these subs!

January 28, 2014

Just as the title says, I love these subs. They sound good, produce the low notes accurately, and hit hard when you want them to. You read reviews where people say "my friend thought I had 10's" It's true. I have used the solobarics since they first came out and everyone always thinks I have larger subs than I do. I currently have two of these 8's in my wife's minivan stuffed in the spare seat storage in the back. They are being run with a Kicker CX600.1 and I am the only one in the family who can stand the music loud enough to make the subs work at all. The website says it needs 0.5 cubic feet of space but I called Stillwater Designs and they said it was a misprint. They only require .33 cubic feet as they always did for their 8" solobaric. My box is .39 each and hits all the way down to 30 Hz before the subsonic filter cuts off the signal. I have another L7 8" in my car run by a Kicker IX500.1 but only needed one as I left the rest of that stero stock and it already overpowers the music.

Great Sounding Sub!

May 16, 2013

I've owned this sub for about 6 months and it really hits hard for a 8" subwoofer. I have it in my regular cab truck and I'm getting ready to put one in my supercrew.

Great subs!

March 11, 2012

I have a 2005 chevy silverado crew cab. I have very little room to put subs under my seat but I found a box with 8" squares cutout so I had to choose between 8" 2 solo barics or 2 10" circular subs and I'm really happy with my decision on buying these L7's! They bump just as hard as my friends setup with 2 12" subs. I'm glad I decided to buy these subs, the low mounting depth is a huge plus! Buy these if you are lacking space, it doesn't get better.

Great value and great product!

February 6, 2012

I was hesitant on buying a set of 8" subwoofers since before this I ran a pair of 15" RE Audio. But since these subs were the perfect size to go under my seat and I could have a back seat again I really am happy with them. I have had no issues with power handling what so ever. I have a US Amps 2000X running them and the subs sound great for just being so small. I would recommend these subs to anyone with space issues. These are defiantly ones that pack a punch.
