Frequently Asked Questions about Ultra XAS12

What power does the Ultra XAS12 from Xcelsus offer?

The Ultra XAS12 Subwoofer from Xcelsus delivers an impressive 500 Watts RMS power. This capacity allows the subwoofer to provide consistent performance even with demanding music pieces. The maximum capacity is 1000 Watts, which shines in peak situations like powerful bass drops or intense soundtracks. Especially at events or installations where loud and clear bass is required, the Ultra XAS12 showcases its full power. The 12-inch diameter, combined with dual voice coils of 4 Ohms each, allows for the highest sound enjoyment in any situation.

What makes the Ultra XAS12 Subwoofer special in terms of sound?

The Ultra XAS12 Subwoofer is characterized by its paper cone, reinforced with fibers, and a rubber surround. This construction gives the subwoofer exceptional stiffness and stability, leading to a clear and precise sound image. The cone material mix not only provides powerful bass but also the necessary flexibility to minimize distortion. The sound unfolds optimally, especially in closed enclosures. The magnet size of 175 x 25 mm also contributes to the subwoofer's extraordinary bass precision, which is unmatched in its class.

What types of enclosures are ideal for the Xcelsus Ultra XAS12?

The Ultra XAS12 from Xcelsus is specifically designed for closed enclosures. This type of enclosure maximizes the precision and clarity of the bass, which is particularly appreciated in high-quality sound installations. The closed design reproduces deep bass cleanly and results in tighter bass response. Closed enclosures minimize cabinet vibrations and unwanted resonances, which in turn optimizes sound quality. Its Thiele Small parameters, such as a Vas of 68.0 liters and Qts of 0.40, support adaptation to various enclosure types to effectively produce deep bass.

How deep does the bass of the Ultra XAS12 from Xcelsus reach?

With a resonance frequency (Fo) of 32 Hz, the Ultra XAS12 Subwoofer from Xcelsus is capable of reproducing particularly deep frequencies. This means that even the lowest tones in music and film soundtracks are clear and distinctly audible. The combination of Thiele Small parameters, such as Vas, Qts, and a high BL value of 10.4, supports the subwoofer's ability to project deep bass powerfully and without distortion. The Mms of 147.0 g also indicates that the subwoofer was designed for a powerful bass story and precise bass reproduction.

What technical challenges might arise when installing the Ultra XAS12 Subwoofer?

The installation of the Ultra XAS12 Subwoofer from Xcelsus requires precise work regarding installation and placement. With an outer diameter of 325 mm and a mounting depth of 155 mm, the available space in the vehicle must be carefully measured to ensure proper mounting. The voice coil has a diameter of 3 inches, and its duality with 2 x 4 ohms requires correct wiring to achieve the desired impedance. Improper installation can lead to technical challenges such as impedance incompatibilities. Be sure to consider the magnet size of 175 x 25 mm when planning the positioning.

How can the sound pressure level of the Ultra XAS12 be defined?

The Ultra XAS12 from Xcelsus offers a sound pressure level (SPL) of 89. This SPL value indicates how efficiently the subwoofer converts acoustic energy into sound. A higher SPL means that more volume is produced at the same power, which is important for powerful bass reproduction. Your sound experience will be more intense at a given input, especially at higher levels, ensuring clear and punchy bass. The specific design with the dual voice coil and robust cone material supports this impressive efficiency in everyday use.

Can I combine the Ultra XAS12 with my car?

For the compatibility of the Ultra XAS12 with a vehicle, it is important to consider the dimensions and technical specifications. The subwoofer has a diameter of 325 mm and a mounting depth of 155 mm, which should be matched with the space conditions of the car prior to installation. The dual 4-ohm voice coil allows flexible wiring options to harmonize with the existing car audio system. No specific car brands are mentioned, so the installation should be carefully planned by matching the technical requirements with the physical and electronic parameters of the car.

How does the dual voice coil affect the performance of the Ultra XAS12?

The dual voice coil of the Ultra XAS12, each with 4 Ohms, offers more flexibility in installation and integration into various audio systems. Due to its duality, the overall impedance can be adjusted by connecting it either in parallel or in series. This means better adaptability to amplifiers and power amplifiers, maximizing sound quality. Additionally, the dual coil allows for more efficient power distribution, enhancing the performance of the subwoofer at high volumes without compromising sound quality. This flexibility is particularly advantageous for demanding bass.

What role does the high BL value of the Ultra XAS12 play in sound quality?

The BL value of 10.4 in the Ultra XAS12 from Xcelsus indicates the electromagnetic force in the subwoofer and is central to the efficiency of converting electrical signals into motion, and thus sound. A high BL value means that the voice coil is moved quickly and precisely, resulting in accurate and powerful bass. This significantly improves transient responses and ensures that all bass notes are perceived clearly. For bass enthusiasts who have high demands for accuracy and clarity of sound, a high BL value is crucial.

Is the Ultra XAS12 suitable for a sealed enclosure design?

Yes, the Ultra XAS12 subwoofer from Xcelsus has been specifically designed for a sealed enclosure. This type of enclosure emphasizes the balance between compactness and sound precision. The parameters of the Ultra XAS12, including a Vas of 68.0 liters and a Qts value of 0.40, facilitate adaptation to sealed enclosures to effortlessly produce precise and deep bass. Sealed enclosures provide maximum control over bass reproduction and reduce distortion, which is particularly beneficial for complex musical pieces. Its specific design ensures optimal performance in this configuration.
