Frequently Asked Questions about Ultra SQL XSS12


What power does the Xcelsus Ultra SQL XSS12 Subwoofer offer?

The Ultra SQL XSS12 Subwoofer from Xcelsus delivers an RMS power of 850 watts, while the maximum load capacity is 1250 watts. These power values provide a rich and powerful sound experience, ideal for music lovers who place great importance on intense bass reproduction. The integration of a 3-inch coil mounted in a symmetrical magnet ensures consistent sound quality even at high volumes. The robust pressed paper cone enhances this effect by projecting sound evenly and clearly.

What are the technical parameters of the Xcelsus Ultra SQL XSS12?

The Ultra SQL XSS12 features a variety of technical specifications. The model belongs to the Solidus series from Xcelsus and has a diameter of 12 inches. With a sensitivity of 93 dB, it offers a dynamic frequency range of 20 to 500 Hz. The dual voice coil impedance is 2x2 ohms. The Thiele-Small parameters include an Fs of 32.018 Hz, an Mms of 166.715 g, and a Cms of 148.210 uM/N. The Bl value is 10.872, while Qms, Qes, and Qts are 5.137, 0.567, and 0.511, respectively. Vas is 55.758 liters.

What is the optimal installation location for the Xcelsus Ultra SQL XSS12 in a vehicle?

The installation depth of the Xcelsus Ultra SQL XSS12 is 180 mm, making it versatile for various vehicle models. When installing, attention should be paid to a suitable enclosure design that optimally showcases the specific sound characteristics. For example, a sealed or bass reflex enclosure is recommended, depending on the desired sound profile. The subwoofer should be mounted in a location within the vehicle that allows for even bass distribution, such as in the trunk. A firm and secure installation also ensures consistently high sound quality.

How do the Thiele-Small parameters affect the performance of the Ultra SQL XSS12?

The Thiele-Small parameters are essential for understanding the acoustic properties of the Ultra SQL XSS12. The Fs value of 32.018 Hz indicates the resonance frequency, a key factor for deep bass reproduction. An Mms of 166.715 g shows the moving mass and affects the impulse response. Cms of 148.210 uM/N describes the compliance of the diaphragm suspension. The Bl value of 10.872 is crucial for the speaker's driving force. Qms of 5.137 and Qes of 0.567 impact the mechanical and electrical damping, which is reflected in a total Qts of 0.511.

How does the diaphragm construction affect the sound of the Ultra SQL XSS12?

The pressed paper diaphragm of the Ultra SQL XSS12 provides outstanding stiffness at a low weight, which expands the frequency range of the Subwoofer and increases efficiency. Especially at high volumes, where the Subwoofer can unleash its maximum power of 1250 watts, this design minimizes distortion and enhances sound fidelity. Due to the diaphragm materials, vibrations are quickly damped, allowing for accurate impulse reproduction. The structure of the diaphragm helps to reproduce both fine details and powerful bass accurately, thus ensuring a comprehensive listening experience.

What role does the coil construction play in the sound of the Xcelsus Ultra SQL XSS12?

The strong 3-inch coil of the Ultra SQL XSS12 is integrated into a symmetrical magnet, which ensures outstanding efficiency in converting electrical signals into sound. This design optimizes heat distribution during power peaks and prevents overheating, thereby maintaining consistent sound quality. The coil significantly contributes to the power handling of 850 watts RMS and 1250 watts maximum and critically influences the impedance of the Subwoofer at 2x2 ohms. These features work together to produce a powerful yet detailed sound.

How can the frequency spectrum of the Ultra SQL XSS12 be optimally utilized?

With a frequency range of 20 to 500 Hz, the Ultra SQL XSS12 covers a wide spectrum, particularly accentuating the lower frequencies. For optimal use of this bandwidth, the Subwoofer should be operated in a housing tailored to the vehicle, which optimizes bass performance. Especially in electronic music genres or home theater sound systems, the Ultra SQL XSS12 offers essential sound advantages with its strong bass reproduction and high sensitivity of 93 dB. To minimize distortion, adequate filtering of the audio signal should be ensured.

Can the Ultra SQL XSS12 be installed in different types of vehicles?

Yes, the Ultra SQL XSS12 can be installed in a variety of vehicles, as long as there is sufficient space for the installation depth of 180 mm. Although no specific car brand is mentioned in the description, the versatility in dimensions and the practical 2x2 Ohm impedance provide broad compatibility. It is important to ensure that the Subwoofer is securely fixed during installation to avoid unwanted resonances or vibrations. Depending on the type of vehicle, placement in the trunk or in the rear seat area is recommended to achieve optimal sound results.

Why is the 2x2 Ohm impedance important?

The 2x2 Ohm impedance of the Ultra SQL XSS12 Subwoofer allows for high flexibility in wiring and adaptation to various audio systems. This configuration enables the Subwoofer to be connected both in parallel and in series, adjusting the overall impedance to meet the amplifier's requirements. This is particularly important to achieve the maximum power output of up to 1250 watts and to optimally modulate the sound. Proper impedance matching not only enhances sound quality but also optimizes the efficiency of the entire audio setup.

How important is the Vas value of 55.758 liters for the XSS12?

The Vas value of 55.758 liters indicates how much volume the speaker enclosure should ideally have to achieve the desired bass performance of the Ultra SQL XSS12. A correctly tuned enclosure volume is crucial as it affects the Subwoofer's ability to optimally convert air pressure into acoustic energy. The volume should be carefully calculated to ensure that the Subwoofer's characteristics are not compromised by resonance effects. In combination with other parameters such as Qts and Fs, the Vas value significantly contributes to the sound characteristics.
