Frequently Asked Questions about Sigma SW 130


What is the frequency resonance of the Sigma SW 130?

The Sigma SW 130 from Gladen has a resonance frequency (Fs) of 62.9 Hz. This frequency describes the point at which the speaker naturally wants to vibrate without external stimulation. Such a technical feature plays a crucial role in tuning the sound system in the vehicle and significantly influences the deep bass reproduction. Especially if you enjoy bass-heavy music, this feature is essential for sound quality. A lower Fs would produce deeper frequencies, while the Sigma SW 130 focuses on a punchy bass reproduction. This allows for fine-tuning of music preferences.

What is the significance of the Qts value for the Sigma SW 130?

The Qts value of the Sigma SW 130 from Gladen is 0.44. This parameter indicates the total damping ratio of the speaker, a combination of mechanical and electrical damping. Generally, the Qts value affects the resonance behavior and efficiency of bass reproduction. Speakers with a Qts value below 0.5 are typically better suited for closed enclosures, which is advantageous for many car owners with compact installation conditions. This value helps you choose the ideal enclosure type for your speaker to achieve maximum performance and sound quality.

How loud can the Sigma SW 130 play?

The sound pressure level (SPL) of the Sigma SW 130 is 87.4 dB at 1 Watt/1 meter and 92.2 dB at 2.83 Volts/1 meter. These values show the efficiency of the speaker in converting electrical power into sound energy. A higher SPL value means that the speaker sounds louder, even at lower electrical power. Especially if you want to equip your vehicle with high-quality sound, the SPL is an important criterion. The high efficiency of the Sigma SW 130 allows for powerful music playback without overloading your amplifier.

What are the power specifications of the Sigma SW 130?

The Sigma SW 130 from Gladen offers a nominal power handling (Pe) of 225 watts and a continuous RMS power of 150 watts. These values define the maximum and long-term reliable power handling of the subwoofer. The nominal power is important to ensure that the speaker is not damaged by excessive voltage and current flow. When planning your audio system, you should ensure that your amplifier does not exceed the specified power ratings of the speaker to avoid distortion and damage. The power data is essential for selecting suitable amplifier concepts.

How do the Thiele Small parameters affect the sound quality of the Sigma SW 130?

The Thiele Small parameters of the Sigma SW 130, including values such as Qms of 3.895, Qes of 0.49, and Vas of 7.0 liters, significantly influence the performance and audio quality of the speaker. Qms indicates the mechanical damping, Qes the electrical damping, and Vas the equivalent compliance volume. These parameters determine the quality and deep bass capability of the speaker. Especially when selecting the optimal enclosure type and volume type, these values are crucial. Proper tuning of the parameters leads to clear, distortion-free, and linear bass reproduction, which is particularly relevant in the car interior.

How does the resistance affect the use of the Sigma SW 130?

The electrical resistance Re of 2.63 ohms and the impedance Z of 3.00 ohms of the Sigma SW 130 dominate the efficiency and compatibility with various amplifiers. A lower resistance offers higher sensitivity and better performance at lower voltages. This can assist in selecting your amplifier, as the combined impedance of the amplifier and speaker must lead to a significant adjustment. Especially under high load, sufficient power supply is guaranteed, minimizing distortion and increasing the lifespan of the speaker. Ideal for powerful use in the car.

How should the Sigma SW 130 be installed in the vehicle?

The Sigma SW 130 from Gladen requires precise installation for optimal performance. The depth of the speaker and the size of the enclosure play a central role in your audio equipment. Pay close attention to the dimensions to achieve the best results. A large volume in closed enclosures improves bass performance, and a tight fit minimizes vibrations. Sound quality benefits from a stable mounting in the vehicle. Ensure that the installation site has no air leaks to maximize the transmission of low frequencies. Perfect installation significantly enhances the acoustic effect.

What are the dimensions of the radiation area of the Sigma SW 130?

The Sigma SW 130 has an effective radiation area of 86 square centimeters, which determines its ability to generate sound at certain frequencies. A larger radiation area generally allows for better deep bass reproduction, as more air can be moved. This dimension is crucial for influencing the overall reproduction and structure of the sound and is advantageous compared to smaller speakers. Especially with music featuring deep bass lines, such as in electronic or orchestral pieces, accurate representation through a larger diaphragm area is essential for a pleasant listening experience in the vehicle.

What is the mass of the moving diaphragm of the Sigma SW 130?

The moving diaphragm mass (Mms) of the Sigma SW 130 is 9.69 grams. This value is significant as it determines the dynamic response and efficiency of the speaker. A lower diaphragm mass generally leads to a faster response time of the woofer, increasing the ability to accurately reproduce musical nuances. When integrating into a car sound system, this value focuses on precise bass control, even at varying volumes. Ideal for ensuring an uncolored sound characteristic across different music styles.

How can the Sigma SW 130 be combined with an amplifier?

Thanks to the Re of 2.63 ohms and an impedance of 3.00 ohms, the Sigma SW 130 offers high compatibility with various amplifiers. These values allow for adjustment of the amplifier configuration to ensure optimal power supply. Ensure that the amplifier is designed for the resistance requirements and that the power ratings of 225 watts handling are observed. It is crucial that the amplifier supports the impedance of the speaker without the risk of overloading or underloading. This avoids distortion and guarantees a long lifespan for the speaker.
