Design and Construction: Materials and Build Quality

Woofer Design and Materials

DS Series Woofers

The DS Series utilizes polypropylene woofer cones, chosen for their rigidity, light weight, and resistance to moisture and temperature extremes found in automotive environments. The cones are paired with ribbed polyester foam surrounds that allow for extended cone excursion, resulting in additional bass output and higher SPL (Sound Pressure Level).

The motor structure of DS woofers is adequate but not as robust as higher-tier models. They employ EVC (Extended Voice Coil) technology, which helps with linear excursion and power handling, though not to the same extent as the CS and KS series.

CS Series Woofers

Like the DS series, CS speakers feature polypropylene woofer cones with polyester foam surrounds. However, the CS cones receive additional treatment to enhance their durability and performance. The polyester foam surrounds are UV-treated, making them more resistant to heat and direct sunlight exposure—a significant advantage in automotive applications where environmental conditions can be harsh.

CS woofers also benefit from a more substantial motor/magnet structure compared to the DS series, contributing to cleaner bass reproduction and better overall performance. The EVC technology is more refined in this series, allowing for greater precision in cone movement.

KS Series Woofers

The KS Series represents a significant step up in woofer construction. While still using polypropylene cones, they feature internal dampening to reduce unwanted resonances and vibrations. This dampening results in more accurate midrange detail and tighter bass response.

Instead of polyester foam, KS woofers utilize durable rubber surrounds, which offer better longevity and more consistent performance across a wider range of temperatures and environmental conditions. The rubber surrounds also provide more controlled excursion, resulting in lower distortion at higher volumes.

The magnet structures in KS woofers are considerably more substantial, enabling better control over cone movement and allowing for higher power handling. The voice coil design is also more sophisticated, contributing to improved thermal management and reliability under demanding conditions.

Tweeter Design and Materials

DS Series Tweeters

DS Series speakers feature 1/2-inch PEI (Polyetherimide) balanced dome tweeters. A balanced dome tweeter has a dome placed inside a cone, with equal reproduction area given to both the cone and dome portions. This design provides a smooth high-frequency response with quick, detailed, and spatially-correct imaging.

The zero-protrusion design of DS tweeters is a key feature, ensuring they’ll fit behind factory grilles without any modifications. These tweeters use neodymium magnets, which are small but powerful, allowing for increased volume in high frequencies without adding bulk.

CS Series Tweeters

CS Series speakers also employ 1/2-inch PEI balanced dome tweeters, but with some refinements over the DS series. The tweeters in CS speakers have a low-protrusion design (as opposed to zero-protrusion in DS), which strikes a balance between fitment and performance.

Like the DS series, CS tweeters use neodymium magnets, but with more refined motor structures that allow for better control and clarity in high-frequency reproduction. This results in more detailed and accurate sound, particularly noticeable in vocal clarity and instrument separation.

KS Series Tweeters

The KS Series makes a significant departure in tweeter design by utilizing silk-dome tweeters instead of PEI. Silk is valued in high-end audio applications for its natural and smooth sound reproduction, with less harshness in the upper frequencies compared to harder materials like PEI.

KS tweeters are typically 1-inch (25mm) in size, larger than the 1/2-inch tweeters found in DS and CS models. This larger size allows for better dispersion of high frequencies and improved off-axis response. In component systems, the KS tweeters can rotate and tilt, offering superior mounting flexibility and enabling optimal sound staging.

A unique feature of some KS speakers is the ability to convert between component and coaxial configurations. The woofers’ removable bullet-style phase plug can be replaced with a special adapter, allowing the tweeter to be mounted coaxially when desired.

Crossover Networks

DS Series Crossovers

The DS Series uses simple passive crossover networks integrated into the speaker assembly. These basic crossovers provide adequate frequency division but offer no adjustment options. They’re designed to work with the limited power from factory head units and focus on reliability over sophistication.

CS Series Crossovers

CS Series speakers feature more refined crossover networks compared to the DS series. In coaxial models, these are still integrated into the speaker assembly but with better components that enable cleaner separation between frequency ranges.

In component systems (like the CSS65), CS speakers include separate two-way crossovers with basic tweeter level control, allowing some customization of the sound profile. These crossovers are designed to handle higher power levels and provide more accurate frequency division.

KS Series Crossovers

KS Series speakers, particularly in component configurations, feature sophisticated external crossover networks. These crossovers are precisely tuned for optimal performance and include multiple adjustment options.

The crossovers in KS component systems typically offer high-frequency output attenuation settings (often 0dB, 3dB, and 6dB or similar), allowing users to fine-tune the tweeter level to match their preferences and vehicle acoustics. The crossover components are of higher quality, with better capacitors and inductors that result in lower distortion and more transparent sound.

In the most advanced KS systems, such as the KSMT dual-pod components, separate crossovers are provided for midrange and tweeter, with the tweeters using an 18dB slope and the midranges utilizing a 6dB bandpass design for precise acoustic control.

Technical Specifications and Performance

Power Handling

DS Series Power Handling

The DS Series is designed for modest power applications, making it suitable for factory head units or entry-level aftermarket stereos. Typical power handling specifications include:

Sensitivity

Sensitivity ratings are relatively similar across all three series, typically ranging from 88dB to 92dB (measured at 1 watt/1 meter). However, there are some differences:

  • DS Series: Generally around 90dB for most models
  • CS Series: Also around 90dB, with some larger models reaching 92dB
  • KS Series: Typically 90dB, though the design emphasis is on quality rather than maximum efficiency

It’s worth noting that while sensitivity specifications are similar, the KS Series typically produces cleaner sound at higher volumes due to superior construction and materials.

Sound Quality and Listening Experience

Bass Performance

DS Series Bass Performance

The DS Series delivers adequate bass for an entry-level speaker, representing a clear improvement over most factory speakers. The polypropylene cones and polyester foam surrounds allow for reasonable low-frequency extension. However, the bass tends to be somewhat loose and lacks the definition found in higher-tier models.

These speakers struggle to reproduce the lowest octaves with authority, particularly without subwoofer support. In 6×9 configurations, they can provide more substantial bass due to the larger cone area, but still lack the precision and impact of higher-end options.

CS Series Bass Performance

The CS Series offers notably improved bass response compared to the DS series. The enhanced motor structure and better quality materials allow for tighter, more controlled bass reproduction. The UV-treated surrounds maintain their properties better over time, resulting in more consistent performance.

CS speakers, particularly in 6×9 configurations, can produce impressive midbass impact and reasonable low-end extension. While they still benefit from subwoofer support for the lowest frequencies, they provide a much more satisfying standalone bass experience than the DS series.

KS Series Bass Performance

The KS Series delivers the most refined bass performance of the three. The internally dampened cones minimize unwanted resonances, while the rubber surrounds provide better control over cone movement. The result is tight, accurate bass with excellent definition and transient response.

Even without a subwoofer, KS speakers reproduce bass with remarkable clarity and impact. The bass notes have better separation and texture, allowing listeners to distinguish between different bass instruments more easily. When used as part of a complete system, they integrate more seamlessly with subwoofers, creating a cohesive sound field across the entire frequency spectrum.

Midrange Clarity

DS Series Midrange Performance

The midrange reproduction in DS Series speakers is clear enough for casual listening but lacks the refinement of higher-end models. Vocals are intelligible but don’t possess the warmth and presence that more discerning listeners might desire. Instrumental textures are somewhat simplified, and complex musical passages can sound congested.

CS Series Midrange Performance

The CS Series offers a significant step up in midrange performance. Vocals have better presence and natural warmth, while instruments are reproduced with improved detail and separation. The overall presentation is more balanced and refined, making for a more engaging listening experience.

For many listeners, the CS Series hits a sweet spot in midrange reproduction, offering substantial improvements over entry-level options without the premium price of audiophile-grade speakers.

Instrumental timbres are rendered with excellent accuracy, allowing for a more immersive and emotionally engaging listening experience.

The superior crossover design in KS speakers contributes to a seamless transition between drivers, eliminating the midrange “hole” that can occur in lesser speakers. This cohesive presentation is particularly noticeable in complex musical arrangements, where individual elements maintain their clarity without competing with each other.

High-Frequency Detail

DS Series High-Frequency Performance

The PEI balanced dome tweeters in the DS Series provide adequate high-frequency extension for most casual listeners. They deliver clear reproduction of cymbals, hi-hats, and other treble-rich content without becoming overly harsh. However, the finest details and airiness in recordings can be lost, and there’s a limit to their refinement, particularly at higher volumes.

CS Series High-Frequency Performance

The CS Series tweeters, while also using PEI material, offer improved high-frequency performance over the DS series. The more sophisticated motor structure and better integration with the woofer result in smoother, more extended treble response. High-frequency details are more apparent, and the overall presentation is less fatiguing during extended listening sessions.

The CS tweeters still have some limitations compared to premium options, occasionally exhibiting a slight hardness to their character that’s typical of plastic dome materials.

KS Series High-Frequency Performance

The silk-dome tweeters employed in the KS Series represent a significant upgrade in high-frequency reproduction. Silk provides a naturally smooth response with excellent detail retrieval but without the occasional harshness associated with harder materials like PEI.

The larger size (1-inch vs. 1/2-inch) and superior motor structure of KS tweeters allow for more extended high-frequency response with better dispersion characteristics. This results in a more spacious and three-dimensional soundstage, with improved imaging and placement of instruments within the audio field.

The adjustable tweeter levels in KS component systems allow users to fine-tune the high-frequency response to their preferences and to compensate for the acoustic properties of different vehicles.

Overall Sound Signature

DS Series Sound Signature

The DS Series exhibits a somewhat forward, slightly colored sound signature typical of entry-level car speakers. They’re designed to sound immediately impressive with boosted midbass and treble regions that create an illusion of detail and impact. While this can be pleasing for casual listening, especially at moderate volumes, more critical listeners may find the presentation somewhat artificial.

These speakers are at their best with mainstream pop, rock, and electronic music, where their energetic presentation can be engaging. They’re less suited to acoustic, classical, or jazz genres where tonal accuracy and subtle details are paramount.

CS Series Sound Signature

The CS Series presents a more balanced sound signature than the DS series, with improved linearity across the frequency spectrum. They retain some of the excitement factor that makes Kicker speakers popular but with a more natural and less colored presentation.

The sound is engaging and dynamic, with good detail retrieval and a reasonably wide soundstage. While not entirely neutral, CS speakers strike a good balance between analytical accuracy and musical enjoyment, making them versatile performers across a wide range of musical genres.

KS Series Sound Signature

The KS Series delivers the most refined and natural sound signature of the three. While still recognizably “Kicker” in their character—meaning they don’t shy away from providing impactful bass and detailed highs—they approach the neutrality and accuracy expected of high-end audio equipment.

The balance across the frequency spectrum is excellent, with no particular range dominating the presentation. This allows KS speakers to excel with all types of music, from bass-heavy electronic tracks to delicate acoustic recordings. The sound is detailed without being clinical, impactful without being overbearing, and engaging without being fatiguing.
