4 mid-woofer with Kevlar membrane for powerful bass

The 4 mid-woofer of the Dragster Audio Art Academy AM-4MB uses a Kevlar cone, known for its rigidity and lightness. These properties enable it to deliver pristine and precise bass reproduction even at high volumes. The rubber surround complements the cone by ensuring excellent control over the movement. This reduces distortion while increasing the linearity of the speaker. A heavier cone material could lead to delays in response time, while one that is too light might not provide the necessary stability. Kevlar strikes the perfect balance here, ideal for all music genres.

Solid cast aluminum basket for stability and sound fidelity

The mid-woofer's solid cast aluminum basket provides stability and minimizes unwanted resonances. Aluminum is lightweight yet strong enough to maintain the speaker's structural integrity. This results in clear and pristine sound reproduction without vibrations or unwanted noise. Speakers with less robust baskets may experience material deformation, which impairs sound quality. A heavier basket would further dampen resonances but increase the overall weight of the speaker and complicate installation.

1 ceramic dome tweeter for crystal-clear highs

The 1 ceramic dome tweeter offers exceptional precision in the high frequency range. Ceramic is a robust material that minimizes vibration and enables clear, detailed sound reproduction without distortion. This choice of material allows the tweeter to perform even at high volumes without loss of sound quality. Softer materials could result in overlap and a loss of clarity. Harder materials could reduce sensitivity, which could affect the sound dynamics.

Thiele-Small Parameters: Optimized calculation basis for perfect sound

The mid-woofer's resonance frequency (Fs) is 100 Hz, ideal for powerful bass reproduction in typical music. The mechanical Q-factor (Qms) of 5.45 and the electrical Q-factor (Qes) of 0.43 result in an overall Q-factor (Qts) of 0.40, which represents a balanced ratio of bass reproduction to efficiency. A lower Qts would result in more efficiency but less bass control, while a higher value could expand the bass but with a loss in efficiency. Overall, the system delivers an equivalent air volume (Vas) of 1.5L and maintains a mechanical mass (Mms) of 6.5g—perfectly tuned for a wide range of music.

Impedance and frequency response: Optimal interaction for the best sound

The AM-4MB's 4-ohm impedance ensures compatibility with a wide range of power amplifiers and amplifiers, making it easy to integrate into existing sound systems. The frequency response of 100 to 20,000 Hz allows the speaker to cover a wide range of tones, from powerful bass to clear highs. A higher impedance may limit compatibility with standard amplifiers, while a lower impedance could overload the amplifiers, ultimately affecting the speaker's lifespan.

Klippel optimization for precise sound reproduction

Klippel optimization in Dragster Audio Art loudspeakers ensures precise and detailed sound reproduction. Through meticulous adjustment of the loudspeaker parameters, distortion can be minimized. This is especially crucial for complex musical pieces, allowing even the finest details to be heard. Systems without this optimization can compromise sound quality, even with large investments, especially in demanding listening experiences. Klippel technology is often used in high-end audio equipment, which underscores the value of this speaker set.

Crossover frequency and voice coil material: Fine tuning for the best sound

A precise crossover frequency at 3500 Hz ensures that the midrange and tweeter work seamlessly together. This tuning minimizes crossover losses and ensures that the full frequency spectrum is driven evenly. The voice coil diameter of the midrange-tweeter system is 1.27 for the midrange and 1 for the tweeter, ensuring consistent performance at varying volume levels. A smaller voice coil could overheat quickly, while a larger voice coil might require a heavier speaker design, complicating installation.

Compatibility with a wide range of Mercedes models

The AM-4MB from Dragster Audio Art is specifically designed for a variety of Mercedes model series, such as the C-, E-, and S-Class. This means installation is easy and requires no special modifications. It guarantees perfect integration in vehicles from the W205, S205, C205, A205, X253, C253, W213, S213, C238, A238, and W222 series from 2013 to 2017. This compatibility eliminates the need for additional adjustments and makes installation straightforward. Speakers that are not vehicle-specific may require adjustments and compromise sound quality.
