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.

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.
