Frequently Asked Questions about AV 12 D2/D4 II

What impedance options does the Audison AV 12 D2/D4 II Subwoofer offer?

The Audison AV 12 D2/D4 II Subwoofer is available in two impedance variants: D2 and D4. The D2 version has a dual voice coil with 2 ohms each, while the D4 version has a dual voice coil with 4 ohms each. These impedance options allow for different wiring configurations to optimally match the subwoofer to various amplifiers. This is particularly important in car audio installations, as it can affect the maximum power output depending on the type of amplifier. Additionally, the choice of impedance influences the electrical and acoustic properties, which is another aspect to consider when configuring the sound system.

What are the dimensions and mounting requirements of the AV 12 D2/D4 II?

The Audison AV 12 D2/D4 II has specific dimensions that must be considered during installation. The overall diameter is 318.3 mm, while the cutout diameter is 5.5 mm. The mounting depth is 102.5 mm, which is important when choosing the enclosure. The recommended enclosure size for this subwoofer is 21 liters with a tuning frequency of 45 Hz. These specifications should be taken into account when installing the subwoofer in a car or other space to ensure optimal performance and a precise fit.

What is the peak and continuous power handling of the AV 12 D2/D4 II Subwoofer?

The Audison AV 12 D2/D4 II Subwoofer offers an impressive peak power handling of 1100 watts, making it suitable for high-performance sound requirements. Its continuous power handling is 550 watts, allowing for consistent power delivery without overheating or power loss. These power ratings enable dynamic sound reproduction even at high volumes, ideal for music lovers seeking intense sub-bass experiences. The amplifier must be appropriately sized to ensure bass reproduction without distortion or signal loss.

What chassis and cone material is used in the Audison AV 12 D2/D4 II?

The Audison AV 12 D2/D4 II Subwoofer uses a robust aluminum chassis that ensures stability and durability. The cone is made of polypropylene, a material that is both stiff and lightweight to minimize distortion and enable precise bass reproduction. This combination of materials, along with a fiberglass basket, optimizes resonance properties and reduces unwanted color effects in the sound image. The choice of materials is crucial for acoustic performance and contributes to a balanced and powerful bass impact that remains stable even at high sound pressure levels.

How do the Thiele-Small parameters affect the performance of the AV 12 D2/D4 II?

The Thiele-Small parameters play a central role in assessing and optimizing the performance of the Audison AV 12 D2/D4 II. With a Vas of 63 liters and a Qts of 0.5, the efficiency of the oscillating system is defined, while an Fs of 23 Hz describes the deep bass range. The BL value of 12.2 T•m indicates the strength of the magnetic control, optimizing precision in diaphragm movement. These parameters help determine the ideal enclosure volume and tuning frequency to adjust the reproduction characteristics and achieve sonically homogeneous results.

What frequency ranges does the Audison AV 12 D2/D4 II cover?

The Audison AV 12 D2/D4 II Subwoofer covers an extensive frequency range from 25 Hz to 400 Hz. This range allows for deep bass reproduction that is both felt and heard, as well as detailed reproduction in the fundamental frequency range. Especially in music genres with pronounced bass drum or bass lines, the subwoofer shines. Its frequency response makes it optimal not only for the lowest tones but also for the representation of fast, rhythmic sequences. This is ideal for enthusiasts who value rich bass and accurate reproduction of lower frequencies.

How does the voice coil improve sound quality in the AV 12 D2/D4 II?

The Audison AV 12 D2/D4 II is equipped with a high-quality CCAW voice coil that significantly contributes to sound quality. The 38.6 mm diameter and 37 mm winding height allow for great linearity and efficiency in sound conversion, while the use of aluminum and copper ensures optimal heat dissipation. This keeps the subwoofer performance stable even at higher sound pressure levels. A good voice coil minimizes distortion, maximizes active sound control, and ensures excellent transient reproduction even in demanding musical passages.

What type of magnet is used in the Audison AV 12 D2/D4 II and why?

The Audison AV 12 D2/D4 II uses a ferrite magnet measuring 156 x 60 x 34 mm. Ferrite magnets are known for their resistance to demagnetization and their sustainability in terms of material costs and environmental friendliness. In conjunction with the precise construction of the Subwoofer, they provide consistent magnetization without audio losses. Especially at high excursions and long operating times, the quality of the magnetic force is evident in a stable, distortion-free sound image. This choice also ensures a long lifespan of the Subwoofer while maintaining performance.

How is the sensitivity of the AV 12 D2/D4 II achieved?

With a sensitivity of 84.5 dB, the Audison AV 12 D2/D4 II is capable of producing remarkable volume even with low amplifier power. The construction of the Subwoofer, based on material synthesis and the precise processing of the polypropylene cone, contributes to its high efficiency. Additionally, the optimized electromagnetic intersection and the voice coil design ensure low energy losses. An efficient Subwoofer requires less power to achieve high volumes, which is particularly advantageous when amplifier resources are limited, allowing for powerful bass production.

What role does weight play in the Audison AV 12 D2/D4 II Subwoofer?

The Audison AV 12 D2/D4 II weighs 6.6 kg, a weight that is related to its stable construction and the selected materials. Aluminum chassis and ferrite magnets increase the overall mass while providing the necessary stability and resonance-free performance. This Subwoofer combines robustness with technical precision and minimizes cabinet vibrations for better sound quality. The weight is also an indicator of the durability and load capacity of the Subwoofer, which is particularly important in mobile applications where the unit may be subjected to greater physical stress.
