Paper membranes are known for their excellent sound properties, as they provide a good balance between weight and stiffness. This results in a fast response time and reduces distortion in the midrange. The natural sound character and clarity are particularly suitable for listening experiences of voices and acoustic instruments. Despite their light weight, the paper membrane offers enough stability to meet the dynamic demands of a high-end vehicle system.
When installing the Gold 11M/4631G05 midrange speaker, the dimensions of 4" (10 cm) are crucial. It is often installed in door or dashboard locations. Its compact size allows it to fit into standard speaker openings. Since a precise fit is important, compatibility with the specific car model should be checked. The aluminum die-cast basket offers flexibility in placement, provided that adequate ventilation and stability are ensured. For optimal performance and sound, attention should be paid to any damping solutions to minimize vibrations.
The Gold 11M/4631G05 midrange driver shows consistent performance at different voltages due to its 4-ohm impedance. This allows it to operate efficiently even with power-hungry amplifiers, which is significant in a high-end audio setup. Its performance remains stable even with fluctuating voltages in the vehicle, minimizing distortion and sound loss. Furthermore, the high-field-strength neodymium magnet supports uniform sound reproduction, even during intense audio sessions. This is particularly advantageous for maintaining sound integrity over a wide range of applications.

The impressive frequency response and resonance frequency at 68 Hz

The Scanspeak Automotive Gold 11M/4631G05 midrange speaker offers an outstanding resonance frequency of 68 Hz. This value ensures that the midrange speaker reproduces low tones precisely and transitions seamlessly to adjacent frequencies. Resonance frequencies in this range are ideal for cars, as they provide sufficient sound volume. If the value drops below 68 Hz, there is a risk of loss of detail at high levels. Higher values ​​could weaken the bass reproduction. This makes the 68 Hz resonance frequency the ideal middle ground for a harmonious soundscape.

Quality and its influence: A Qts value of 0.31 for ultimate sound fidelity

With a Qts of 0.31, the midrange driver is perfectly suited for sealed or bass-reflex enclosures. Such a low Qts value implies greater electromagnetic control of the speaker and reduces sonic distortion. A higher Qts value could result in a softer, but less controlled, reproduction. This Qts is ideally suited for automotive applications and maximizes sonic performance.

Neodymium magnet system: first-class performance in a compact design

The midrange driver's encapsulated neodymium magnet system is a hallmark of high performance in a minimal footprint. Neodymium offers higher remanence than conventional ferrite magnets, resulting in more powerful and efficient performance. Using a different magnet material could reduce longevity and field strength. With this design, Scanspeak Automotive has equipped the midrange driver for demanding requirements.

Lossless linear suspension: Optimal excursion and sound stability

A lossless linear suspension optimizes the movement control of the diaphragm. This means that the sound image remains faithful to detail despite a maximum excursion of ± 3mm. A less than optimal suspension could lead to unwanted sound distortion. This ensures exceptional durability and product stability for use in demanding environments.

Special die-cast aluminum basket: precise stability and durability

The die-cast aluminum basket increases the stability and minimizes microvibrations of the Scanspeak Automotive midrange driver. Aluminum is lightweight yet robust, ideal for powerful sound experiences. Its dimensional stability during temperature fluctuations is advantageous. If a different material had been chosen, unwanted resonances could occur, which aluminum reliably eliminates.

Pole core drilling with elegant grille: protection and aesthetics harmoniously combined

Another highlight is the grille in front of the pole piece hole. It protects the speaker from dirt particles and simultaneously harmonizes air circulation inside, which allows conclusions to be drawn about pristine sound reproduction. A lack of protection could compromise long-term durability, which is why this component is essential. Furthermore, the grille elegantly complements the stylish design of the midrange driver.

Connection options: Flexibility through 4 ohm impedance

With an impedance of 4 ohms, the midrange speaker offers flexible connection options to automotive amplifier systems. This value strikes a perfect balance between sound quality and power consumption. Higher impedances could result in quieter speakers, while lower impedances potentially place maximum demands on the amplifiers. The 4 ohms impedance is therefore ideal for dedicated use.

Precise 4 (10cm) diaphragm dimensions: Optimal balance of size and performance

The Scanspeak Automotive midrange speaker features a key design component: the 4 (10cm) paper cone. Paper as a cone material offers an optimal weight-to-stiffness ratio and fuels the natural sound performance. A smaller cone could reduce detail, while larger dimensions may negatively impact installation space. The 4 size ensures that the midrange speaker can be integrated into the car in a variety of ways.

Highly sensitive sound level: 90 dB for sonic brilliance

The 90 dB sensitivity makes the midrange driver extremely efficient in terms of sound power per watt of input. This reduces the need for a particularly powerful amplifier to achieve high sound levels. A significant variation in this figure could result in unbalanced sound reproduction. Highly sensitive drivers like this are essential for sustained audio performance.

Mechanically outstanding parameters: Thiele-Small parameters

Thiele-Small parameters such as Vas at 2.7 liters, Bl of 5.5 Tm, and Sd of 50 cm² define the mechanical properties of this midrange driver. Vas influences how the speaker operates within the cabinet, while Bl reflects the efficiency of force transmission to the cone. An increased Bl, for example, could improve impulse fidelity. The dimensions are finely tuned to optimally embed the midrange driver in the vehicle's acoustics and deliver a first-class listening experience.
