Due to the membrane materials, vibrations are quickly dampened, allowing for accurate impulse reproduction. The structure of the membrane helps to reproduce both fine details and powerful bass precisely, thus guaranteeing a comprehensive listening experience.
The powerful 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 a consistent sound quality. The coil significantly contributes to the robustness of 850 watts RMS and 1250 watts maximum, and it critically influences the impedance of the subwoofer at 2x2 ohms. These features work together to produce a powerful yet detailed sound.
With a frequency range of 20 to 500 Hz, the Ultra SQL XSS12 covers a wide spectrum, particularly accentuating the lower frequencies. For the best possible 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 sound systems for home theater applications, 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.
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 as well as 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 area of the rear seat bench is recommended to achieve optimal sound results.
The impedance of 2x2 Ohm in 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 total impedance to meet the amplifier's requirements. This is particularly important to achieve maximum power output of up to 1250 watts and to optimally modulate the sound. By properly matching the impedance, not only is the sound quality enhanced, but the efficiency of the entire audio setup is also optimized.
The Vas value of 55.758 liters indicates how much volume the 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 adversely affected by resonance effects. In combination with other parameters such as Qts and Fs, the Vas value significantly contributes to the sound characteristics.
