Frequently Asked Questions about Voce II AVBX 12 D4 II

What is the nominal diameter of the Voce II AVBX 12 D4 II Subwoofer?

The Voce II AVBX 12 D4 II Subwoofer from Audison has a nominal diameter of 300 mm or 12 inches. This size is crucial for the subwoofer's ability to produce deep tones. With a larger diaphragm area of 539 cm², a more intense and voluminous bass can be achieved, which is often lacking in traditional speaker systems. Especially if you enjoy listening to music at high volumes, you will appreciate the dynamics and pressure that a 12-inch chassis can deliver compared to smaller diameters.

What is the power handling of the Voce II AVBX 12 D4 II?

The Voce II AVBX 12 D4 II has a continuous power handling of 550 watts and can handle peak loads of up to 1100 watts. This high power handling allows the subwoofer to be detailed and precise even in quiet passages, while also operating distortion-free at high volumes. The dual voice coil with 4+4 ohm impedance is specifically designed to meet the demands of modern amplifiers, making it suitable for both high-efficiency systems and high-performance applications.

What materials were used for the Voce II AVBX 12 D4 II?

The Voce II AVBX 12 D4 II is made from a mix of materials that optimize its performance. The basket is made of aluminum, which increases stability and minimizes vibrations. The diaphragm is made of polypropylene with mica injection, ensuring precise and clean sound reproduction. Additionally, a rubber surround improves the flexibility and excursion of the diaphragm. The magnet material is high-density ferrite, which ensures stable and powerful operation, ideal for demanding bass lines.

What frequencies does the Voce II AVBX 12 D4 II cover?

The frequency response of the Voce II AVBX 12 D4 II ranges from 25 Hz to 400 Hz. This allows the subwoofer to cover very low tones that are felt more than heard, as well as mid-bass tones. The low frequencies are particularly important for fully perceiving the richness of a piece of music. Additionally, the resonance frequency of 23 Hz provides particularly deep bass reproduction, which is remarkable in the league of hi-fi subwoofers.

What is the net volume of the Voce II AVBX 12 D4 II Subwoofer?

The Voce II AVBX 12 D4 II has a driver displacement that offers a net volume of 0.9 liters. This specification is crucial for the design of the enclosure into which the subwoofer will be installed. Depending on the chosen enclosure type, this volume can influence the bass reproduction. A correctly tuned enclosure ensures that the subwoofer operates optimally and delivers the desired sound character without unwanted resonances.

What electrical points should be considered for the optimal operation of the Voce II AVBX 12 D4 II?

For the Voce II AVBX 12 D4 II, several electroacoustic parameters must be considered: The total quality factor (Qts) is 0.5, indicating suitability for both sealed and vented enclosures. The DC resistance (Re) of 1.8 Ohms is crucial for power output and must correspond with the Amplifier. The drive factor (BL) of 12.2 T•m supports strong magnetic force for dynamic playback. Additionally, the maximum excursion (Xmax) of 16.8 mm should not be exceeded to ensure the longevity of the Subwoofer.

What tips are there for installing the Voce II AVBX 12 D4 II in a car?

When installing the Voce II AVBX 12 D4 II in a car, attention must first be paid to the dimensions: The outer length is 607 mm, the outer width is 401 mm, with a cabinet depth of 175 mm. These measurements require a suitable placement choice in the vehicle to correctly integrate the Subwoofer. For installation, the protrusion of 35.2 mm and the internal depth of 133 mm must be considered. Proper placement is crucial to fully exploit the acoustic advantages of the Subwoofer.

What Thiele-Small parameters does the Voce II AVBX 12 D4 II have?

The Thiele-Small parameters of the Voce II AVBX 12 D4 II provide important information for the construction and tuning of enclosures. The resonance frequency (Fs) of 23 Hz indicates excellent suitability for deep bass reproduction. The equivalent volume (Vas) of 63 liters supports flexibility in enclosure choice. The maximum excursion (Xmax) of 16.8 mm and the total quality factor (Qts) of 0.5 are critical for designing enclosures to ensure optimal performance.

How does the sensitivity of the Voce II AVBX 12 D4 II affect the sound?

With a sensitivity of 84.5 dB, the Voce II AVBX 12 D4 II provides a solid foundation to achieve impressive volumes even at moderate amplifier power levels. This sensitivity means that the Subwoofer requires less amplifier power to operate at a given volume, which is advantageous in environments with limited power supply. Especially in vehicles with a complex arrangement of Hi-Fi components, this can be crucial for achieving powerful and clear bass.

How compatible is the Voce II AVBX 12 D4 II with different vehicles?

Although no specific car brands are mentioned for the Voce II AVBX 12 D4 II, the compact dimensions allow for versatile installation options in numerous vehicle models. The dimensions of the Subwoofer—particularly an outer length of 607 mm and an outer width of 401 mm—fit into many common vehicle technical structures. However, the installation height of 175 mm and the protrusion of 35.2 mm should be noted. This ensures that no vehicle components are affected and the Subwoofer can be optimally integrated.
