From top to bottom, Kicker builds the Solo-Baric L5 subs for powerhouse bass. The 06S15L54 15" subwoofer features Kicker's trademark square woofer cone, crafted from composites and treated with aluminum — it's rigid, responsive, and ready for hard-hitting, accurate playback at extreme sound pressure levels. The tough, tear-resistant Santoprene rubber surround includes reinforcement at the edge of the cone for added durability.

A sturdy steel basket holds these elements in place, while air vents around the sub's perimeter pump the hot air away from the interior. Kicker's UniPlate pole piece and backplate allow extended cone travel, so the sub won't distort when the lows start bumping. The two 4-ohm voice coils offer the wiring flexibility you'll need to use your sub in either high output or multiple woofer configurations.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Features

Dual Voice Coils: For increased system flexibility, the woofer has two 4-ohm voice coils. When the voice coils are wired in parallel the woofer presents a 2-ohm load. When the voice coils are wired in series the woofer presents an 8-ohm load. In addition, each coil may be connected to a different amplifier channel and each channel will see a 4-ohm load.

Square Design: By making the Solo-Baric square, Kicker is giving you the most possible cone area (Sd) for a given size baffle, 16% to 20% more area than a conventional round subwoofer. More cone area means the Solo-Baric L5 moves more air, resulting in louder, deeper bass.

Cone Materials: The square cone is made of SoloKon, an ultra high performance composite, which remains rigid, minimizes cone flex and lowers harmonic distortion. SoloKon consists of a unique one-piece, aluminum vapor-deposit material that moves as a lightweight piston, exhibiting power and control. A rear cone brace integrates into the SoloKon with a continuous contact perimeter weld, which offers unmatched strength and resistance to deformation under pressure.

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, even in the harshest conditions.

Spider: The woofer is equipped with a wide poly-cotton spider which easily handles high cone excursions due to its increased diameter and unique shape.

Enhanced BAM (Basket And Motor) Assembly: The Solo-Baric L5 utilizes a high strength stamped steel basket which features a low-profile open design and provides a solid foundation for the precision-aligned motor assembly. Perimeter venting in the BAM relieves pressure from under the spider, supports linear excursion, and helps dissipate heat from the voice coil and motor structure.

UniPlate Construction: The Solo-Baric L5 features a one-piece UniPlate construction with a vented hyper-extended pole piece and backplate. This unique design provides the following benefits:

  • Optimizes heat transfer efficiency for cooler operation and maximum power handling ability
  • Eliminates erratic magnetic flux from the voice coil gap
  • Releases pressure under the suspension for uniform cone movement and responsive low bass
  • Prevents the voice coil from bottoming out and corresponding damage

Tinsel Lead Wires: The sleeved, high-power tinsel lead wires eliminate broken leads and power loss due to the common use of insufficient-gauge lead wires. The lead wires are stitched to the spider to relieve stress on the connections.

Rubber Magnet Boot: A black rubber boot covers the outside edge of the magnet structure to improve the cosmetics of the woofer and protect the magnet from chipping or breaking during installation.

Speaker Terminals: The terminals are spring loaded and nickel-plated for solid connections with heavy gauge speaker wire, up to 11 gauge.

Break-in Period: Due to the complex nature of Kicker Solo-Baric L5 woofers, they require a break-in period in order to produce optimum low-bass response. The high-performance suspension system makes the speakers very stiff "out-of-the-box". Approximately 2 weeks of daily playing will allow the suspension to break-in and reach its optimum equilibrium. A "broken-in" subwoofer will exhibit stronger bass performance, smoother response, and greater low-bass extension.

Enclosure Compatibility

Power Handling: The power handling specifications differ according to the type and size of the enclosure. The power handling specifications assume that both voice coils are in use.

Note: Both voice coils in a dual voice coil speaker should always be connected.

Recommended Sealed Box Volume:

  • Compact (minimum enclosure volume): 1.5 cu/ft; the woofer can handle up to 750 watts RMS
  • SQ (maximum enclosure volume): 6.0 cu/ft; the woofer can handle up to 450 watts RMS

Recommended Vented Box Volume:

  • Compact: 3.0 cu/ft; 2.5" x 16.25" port opening; 19.5" port length; the woofer can handle up to 750 watts RMS
  • SPL/Deep Bass: 6.0 cu/ft; 3.5" x 16.25" port opening; 13.75" port length; the woofer can handle up to 750 watts RMS

Note: The power handling specifications listed with the vented enclosure recommendations apply only when a 25Hz, 24dB/octave subsonic filter (sold separately) is used with this woofer. If a subsonic filter is not used, power handling may decrease, excessive port noise can occur, and the life of the woofer may be shortened.

Cutout: The woofer will not mount in a standard enclosure with a round cutout. Instead, the woofer must be mounted in an enclosure with a 13.659" x 13.659" square opening.

Major Knock

Written By Robert, Austin, Tx on Tuesday, July 08, 2008

I am running two of these on two 1000 amps, and simply put, they get it DONE. They absolutely knock, just make sure not to skimp on the Dynamat. It is necessary with these subs!!!

insane

Written By jay, bemidji,mn on Friday, February 29, 2008

these suebs r insane when u fully power them and i tell u what they can take more then what there rated at i have this one sub along with a zx750.1 and the lows r amazing...great sub must have. i know the owner of a kicker explorer suv with 2 18's and 4 2500 watt kicker amps and he hits 164-166db so maybe u wanna get a better db tester and u might find that ur really right around 145-149db depending on the amp ur running...i had 2 12" L5s with a zx850.2 and i was hitting 143.3db in my durango.

Nothing Else Comes Close

Written By joseph, Virginia on Friday, February 22, 2008

These are by far the best subs i have ever owned. Having previously owned a pair of the original Kicker Competition 12s (now known as comp vr), i knew Kicker was a sure fire bet. I have these in a 98 cherokee limited, in a custom fiber-glass box that literally fills the entire back end of the vehicle. These subs can literally make the scenery in front of you difficult to concentrate on. Please take my advise and add Dynamat Extreme to your ENTIRE vehicle to make the most of these. I have 3000 watts on mine and without dynamat i thought my jeep would fall apart at anytime.....after dynamat.......nothing but deep low bass as far as the ears can hear. These subs pound so hard anyone in the backseat when the bass kicks on, literally gets their hair blown up in the air as the air leaves the ports in front of the box. I dB rated around 165 dB with this setup and i will never have anything but kicker products........amps, subs......kicker is god.

NO JOKE

Written By javier, Miami, FL on Sunday, September 17, 2006

I have 2 of these in a 1992 s10 blazer in a ported box with an amp giving them around 1500 watts. BELIEVE ME these things can take alot more. It is impossible to explain how much these things pound, you can't see straight when these things are on. Kicker is honestly top of the line. Props to Kicker for making these subs. Not just loud, loud and clear, not muddy retarded bass.

banging

Written By Dmoney, Dallas,Tx on Wednesday, June 28, 2006

Sheer Power

Written By Ben, Harwich, MA on Thursday, April 20, 2006

I own one 15" Kicker L5 and this thing slams! I have it powered by an audiobahn amp running at 800 watts rms and believe me this sub can take more. If you are looking for nothing but flat out brain rattling bass at a good price, than this is your sub.
This sub is well made and reliable, the thing will last a long time and only takes a short time to break in. But when you do..... get ready because it will make your trunk cry. The sound quality is great, the distortion is nonexistent, and for a big sub it doesn't miss many high hits at all. If you did buy this, i would recommend buying dynamat because it makes a great deal of noise outside the car.

Get everything you’ll need to enjoy your new Kicker Solo-Baric L5 06S15L54

Reduce ambient road noise and your vehicle's "rattles," for better sound inside your car.
Add a grille and keep your sub safe.
