Frequent questions about Ultra XAS12

Welche Leistung bietet der Ultra XAS12 von Xcelsus?

The Ultra XAS12 subwoofer from Xcelsus offers an impressive 500 watts RMS power. This load capacity allows the subwoofer to deliver consistent performance even with demanding music pieces. The maximum load capacity is 1000 watts, which comes into its own in peak load situations such as powerful bass drops or intense soundtracks. Especially at events or installations where loud and clear bass is required, the Ultra XAS12 unleashes its full power. The 12-inch diameter, combined with a dual voice coil of 4 ohms each, allows you to enjoy the highest sound quality in any situation.

Was macht den Ultra XAS12 Subwoofer klanglich besonders?

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

Welche Gehäusetypen sind ideal für den 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 allows for clean reproduction of deep bass, resulting 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.

Wie tief reicht der Bass des Ultra XAS12 von Xcelsus?

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 clearly 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 has been designed for a powerful bass performance and precise bass reproduction.

Welche technischen Herausforderungen könnten bei der Installation des Ultra XAS12 Subwoofers auftreten?

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 installation. The voice coil has a diameter of 3 inches, and its duality of 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.

Wie lässt sich der Schalldruckpegel des Ultra XAS12 definieren?

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 with the 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.

Kann ich den Ultra XAS12 mit meinem Auto kombinieren?

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 checked against the space available in the car prior to installation. The dual 4-ohm voice coil allows for 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.

Wie beeinflusst die Doppelschwingspule die Performance des 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 the sound. 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.

Welche Rolle spielt der hohe BL-Wert des Ultra XAS12 für den Klang?

The BL value of 10.4 in the Ultra XAS12 from Xcelsus provides information about 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 differentiated. For bass enthusiasts who have high demands on the accuracy and clarity of sound, a high BL value is crucial.

Ist der Ultra XAS12 für eine geschlossene Gehäusekonstruktion geeignet?

Yes, the Ultra XAS12 subwoofer from Xcelsus has been specifically designed for a sealed enclosure construction. 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 develop precise and deep bass. Sealed enclosures provide maximum control over bass reproduction and reduce distortion, which is particularly advantageous for complex musical pieces. Its specific design ensures that it operates optimally in this configuration.

Super guter Subwoofer

Super Subwoofer mit extrem tiefem Bass. Die Kabel sind dick und hochwertig verarbeitet. Es gibt nichts zu beanstanden. Absolut empfehlenswert.

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

X-10 v3 d2

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.

Top Upgrade für Canton System

Ich habe den Woofer in meinem Skoda Octavia 3 mit Canton Soundsystem eingebaut.
Der Einbau war Plug & Play, alles passt perfekt ohne Anpassungen.
Im Vergleich zum originalen Canton Subwoofer spielt dieser deutlich stärker, präziser und mit mehr Druck.
Ich kann den Woofer jedem empfehlen, der mehr Bass aus dem Canton-System herausholen möchte – lohnt sich absolut!
