Frequently Asked Questions about GS12-Slim

What are the dimensions of the GS12-Slim from Gladen?

The GS12-Slim from Gladen has an outer diameter of 330 mm and a mounting diameter of 305 mm, which is significant when fitting the Subwoofer into standard openings in vehicles. With a mounting depth of only 100 mm, the GS12-Slim is particularly slim and offers flexibility in installation, even in tight vehicle spaces. Due to its slim design, it is suitable for various vehicle types where trunk or under-seat space is often limited. These dimensions allow for elegant integration of the Subwoofer without sacrificing much usable space.

What electrical properties does the GS12-Slim have?

The GS12-Slim has a nominal impedance of 2x2 Ω, allowing for flexible control in various configurations, such as parallel connection for a lower total impedance. With a DC resistance (Rdc) of 3.56 Ω, control and precision of the diaphragm movements are improved. Another important aspect is the force factor (BL) of 11.17 Tm, which describes the driving force of the magnetic field on the voice coil, thus enabling very substantial bass. These specifications are crucial for optimal integration into complex sound systems.

What information is available about the diaphragm and voice coil diameter of the GS12-Slim?

The diaphragm of the GS12-Slim is made from coated paper membrane, combining stability and damping properties for clean bass reproduction. This design reduces distortion and resonance effects, leading to precise sound quality. The voice coil diameter is 2.5 inches (approximately 63.5 mm), ensuring excellent performance at high volumes. Additionally, the voice coil height of 30 mm provides enough space in the air gap for efficient power transfer. These components are responsible for the speaker's high load capacity and responsiveness.

What enclosure volumes are recommended for the GS12-Slim?

For the GS12-Slim from Gladen, two enclosure volumes are recommended: 45 liters for a vented enclosure and 25 liters for a sealed enclosure. The sealed enclosure of 25 liters is ideal when a quick, tight bass response is desired, which can be particularly advantageous in small vehicles. The vented design with 45 liters supports air circulation and allows for a more voluminous deep bass, ideal for large trunks or home applications. This flexible volume choice allows the Subwoofer to be adapted to the acoustic requirements and spatial conditions.

How does the resonance frequency of the GS12-Slim affect bass performance?

The resonance frequency of the GS12-Slim is 26.5 Hz, indicating its ability to reproduce low frequencies with high efficiency and minimal power loss. A low resonance frequency means that the Subwoofer can provide excellent performance at very low tones. Especially if you enjoy music that heavily relies on deep bass, this is a crucial advantage in achieving the desired sound quality. This frequency ensures that the driver enjoys deep and powerful bass without having to excessively strain the Subwoofer.

How do the Thiele-Small parameters of the GS12-Slim affect installation?

The Thiele-Small parameters of the GS12-Slim, such as the mechanical quality (Qms) of 5.64, the electrical quality (Qes) of 0.49, and the total quality (Qts) of 0.45, provide insight into the suitability for different types of enclosures. While a higher Qms indicates some mechanical damping in the system, the lower Qes points to strong electrical control, which is crucial for integration into car sound systems. Together, these parameters influence bass support in the chosen enclosure, whether sealed or vented, and optimize the efficiency of bass reproduction.

What information is available about the moving mass and diaphragm area of the GS12-Slim?

The moving mass (Mms) of the GS12-Slim is quite moderate at 183.6 g, which directly affects the sensitivity and maximum displacement of the diaphragm. The generous diaphragm area of 551.5 cm² contributes to creating a powerful bass foundation. This combination optimizes the reproduction of low frequencies and ensures impressive bass dynamics while maintaining precision and low distortion. Especially in performance-oriented audio configurations, such as in large vehicles or among enthusiasts, this leads to remarkable sound reproduction.

What mechanical features influence the performance of the GS12-Slim?

The steel basket provides the GS12-Slim with a stable and resonance-free foundation to minimize vibrations and thus optimize sound quality. The mechanical resistance (Rms) of 5.42 kg/s and the compliance of the suspension (Cms) of 0.197 are also essential factors that influence the dynamic properties of the subwoofer. These parameters ensure balanced behavior during oscillating movements and offer an ideal combination of stability and flexibility for the diaphragm movements. This guarantees consistent and precise bass reproduction, especially at high volumes.

What is the sound pressure level of the GS12-Slim and why is it important?

The sound pressure level (SPL) of the GS12-Slim is 89.02 dB at 2.83V/1m, indicating a high sensitivity of the speaker. A higher SPL value means that the speaker requires less energy to produce a certain volume level, which is particularly advantageous when directly connected to less powerful amplifiers. This efficiency is crucial if you prefer powerful bass sounds with low power consumption and desire a high headroom. The SPL value ensures optimal volume and clarity of sound under various acoustic conditions.

How should the GS12-Slim be optimally installed in the vehicle?

When installing the GS12-Slim in the vehicle, you should ensure that the enclosure is designed according to the recommended volume specifications. The closed enclosure with 25 liters is suitable for compact installation locations, while the vented enclosure with 45 liters is helpful for extended bass reproduction. The included mounting ring facilitates the attachment of the subwoofer. Note the installation diameter of 305 mm and the installation depth of 100 mm to ensure that there is enough space. The included protective grille also provides additional protection for the diaphragm when installed in unprotected areas of the vehicle.
