As you may already know, the Kicker brand features exceptional products, especially when it comes to their subwoofer line. They consistently design subwoofers that out-perform the competition. Today we are going to discuss two Kicker subwoofers that have different styles and power ratings, yet both stand out in today’s line of car audio subwoofers.

The Kicker CompVR subwoofer line delivers high-performance sound with superior bass and durability. The Kicker 07CVR124 12” Dual 4 ohm subwoofer is part of the CompVR line. The power handling is simply amazing since it pushes 400 watts RMS. The CompVR’s are made with a polymineral injection molded cone that remains rigid and lowers distortion. This unique cone eliminates flex by using a 360-degree back bracing and aluminized coating.  The top-plate design, dual voice coils and motor structure allow the sub to handle intense power without breaking down.

Looking for something with less power, but still has that great Kicker name.  The Comp Series is perfect for someone who wants just enough quality and bass without breaking the bank. The C104 is a 10” Single 4 ohm subwoofer capable of pushing 150 watts RMS. The vacuum formed polymineral cone and ribbed surround are stitched together for durability and strength. This woofer will provide good solid bass that is going to last you a long time.

As you can see, Kicker subwoofers will work great for any application. They represent the best balance between high-value and high-performance in today’s market.

Kicker Audio Overview

kicker car audio

By Seth Wilde – Host of Sonic Electronix TV

Here at SonicElectronix.com, we strive to offer the best customer service possible.  Part of customer service is having the knowledge to answer questions that customers have about products.  In order to accomplish this, training sessions are held on a regular basis to augment the knowledge of the SonicElectronix.com staff.  Recently, representatives from Kicker Car Audio came to our building to provide training on all of the Kicker products out there!

They began their training with a brief history of Kicker, explaining that it was started in 1980 when the founder Steve Irby developed the first full-range speaker box made specifically for the car.  In 1986, Kicker released both the Competition woofer, known as the original small box woofer, and the Freeair woofer, which was designed specifically for free air applications.  By 1992, Kicker introduced the first Kicker Solo Baric subwoofer.  One year later they released their first fully regulated power supplies and amplifiers.  Kicker continued devising innovative products and in 2000 the world’s first Kicker Solo-Baric L7 square subwoofer was released.  As they developed more and more products, the Kicker technology advanced more and more. Such technology includes the unpiloted, stitched surrounds, extended pole pieces, T and L cut top plates, Inverted Structural Dome (I.S.D.), perimeter venting, and the S.P.A.I.R re-cone kit.

Before talking about their full line of subwoofers, they explained the principle of having a square subwoofer.  Like many ingenious innovations, the principle behind the design is pretty simple.  Square subwoofers provide the most cone area for the size of the speaker box baffle.  On average, a square subwoofer has about 25% more cone area than a round subwoofer of the same size.  More cone area means that the subwoofer is able to move more air and thus it will produce more bass.

After talking about some of the incredible technology that goes into making a Kicker sub, the Kicker representative began to talk in detail about each of their products.  It was an unbelievably informative training session.  They were able to answer every single question despite the fact that our representatives asked some pretty detailed questions!  We learned about the three major square subwoofers: the Solo X, the L7, and the L5.  These square woofers are created with unique specifications to maximize their performance.  The Solo X is Kicker’s competition and extreme woofer. The Solo X includes a S.P.A.I.R. re-cone kit, which allows you to maintain and repair the cone throughout the lifetime of the sub.  The L7 is the original square subwoofer and Kicker’s best selling square subwoofer.  The L5 is Kicker’s most affordable square subwoofer and provides 70% the performance of the L7, but for a fraction of the price.  Both the L5 and L7 subs are available in preloaded boxes that Kicker manufacturers specifically for these subs.  They are finely tuned to the specs of the enclosed woofer and provide the best sound for that woofer.

Along with the square subs, we also learned about the round woofers.  The Kicker CVX is the best performing round subwoofer and is essentially a round L7. New to the 2009 Kicker line-up is the Solo Classic, which produces the same amount of bass in only half of the space.  Next we discussed the CVT subwoofers. The CVT line features subs in a variety of sizes, which makes it easy to find the proper fit for your install application.  Then we learned about the Comp VR (CVR). The CVR is Kicker’s best performing “value” subwoofer.  When enclosed in a ported box, the Kicker CVR is able to produce some big bass!  Lastly we learned that the Kicker Comp is the industry leading subwoofer and bestseller.  They are highly efficient subs with moderate power and big Kicker bass.  The Kicker woofers use a SoloKon cone that is ultra strong and injection molded to enhance the sound of the woofers.  With a Kicker subwoofer, loud bass is practically guaranteed!

After completing subwoofer training, we began to discuss the full line of Kicker speakers.  At first we discussed the newest QS and RS speakers.  The QS components are Kickers premium speaker system and use Kickers most advanced technology and engineering to create the ultimate sounding speaker.  The crossover on the QS speakers use an asymmetrical design and a Zobel Impedance correction network to spread the response across the entire speakers; bandwidth.  The crossover also integrates an Illuminated protection circuit, as well as Mylar caps and air core inductors. Judging from the demonstration, the QS speakers sound absolutely phenomenal.  We were just getting started though. After learning about the QS speakers, we began to discuss the high-end RS series speakers.  Apparently the RS speakers have been redesigned for 2009 and use a lot of the same technology and engineering as the QS.  The main differences between the two are the materials and the crossover.  The RS features a slightly simplified version of the QS crossover, but it still has all of the necessary features of a high-end speaker.  Finally, we briefly talked about the KS and DS series speakers.  We learned about the polyswitch tweeter protection on the KS speakers and the perfect OEM upgrade for the DS series speakers.

After discussing subs and speakers, we were ready to learn about amplifiers. This was one of the highlights of the training.  We got to see the amplifiers inside and out.  We learned what makes a Kicker amp a Kicker amp.  The quality and precision that goes into each and every amplifier is second to none.  We were most impressed with the thorough quality control involved in the production of ZX amplifiers. Each and every ZX amp is tested before it leaves the factory.  The spec sheet that is included in each amp tells the tested RMS wattage of the amplifier and each one is underrated.  This way, when a customer purchases a ZX amplifier, they are getting more than what they paid for!

After finishing the major categories, we moved to more specialized fields like marine technology. In fact, the Kicker power sports line includes but is not limited to marine series speakers, subs and amps. We learned that Kicker now refers to the marine series as the power sports series because these items are completely designed to withstand harsh conditions in general and not just in the boat.  Power sport models are made to work perfectly on boats, jeeps, ATV’s, patios, in the backyard, and even zambonis!  The Kicker Power Sports amplifiers, speakers, and subwoofers are perfect for any application that might require a more durable and protected item.

Next we learned about Kicker’s mobile audio products. The Kicker experts taught us all about the SoundGate iPod and Zune accessories.  The Kicker CORE system is designed to provide playback of your iPod in your car.  All of the cables are included, making it easy to get started. The CORE also provides 5V USB charging.  These systems will allow playback from the iPod itself and can even connect and play video from the iPod!  Next we discussed the SoundGate iO series, a new way to integrate your iPod and other audio source to your car via Bluetooth!  The plug and play system allows for Bluetooth audio, handsfree communication, and music streaming.  It is still in the development stages and has yet to be released, but it will be the ideal solution for adding Bluetooth and navigation voice guidance to vehicles that are not suitable for aftermarket in-dash head units. It would make an excellent addition to classic cars!

The last thing we were trained on was the home and portable line.  This includes Kicker headphones and their iPod shelf systems.  The headphones include high performance ear-buds and an active style “on-the-ear” headphone.  The ear buds produce incredible acoustic sound quality given their slight dimensions. These headphones are perfect for the on-the-go listener.  The active style headphones are made for those that live an active lifestyle and need a headphone that will stay on the head.  Beyond that, we learned about iPod docking shelf systems such as the iK500. Based on the demonstration, this system provides iPod playback through loud and clear speakers that fill the entire room with music.  For those that enjoy a Zune as opposed to the iPod, Kicker makes the ZK500, which is similar in features but designed to dock and play the Zune.

We here at SonicElectronix.com were impressed with the training seminar and we are blown away at the quality of Kicker products.  The Kicker representatives were extremely knowledgeable and knew everything about their products.  Kicker is definitely a high quality company that takes as much care of its products as they do their customers.
