Frequently Asked Questions about Prima APS 8 D

How much power does the Prima APS 8 D Subwoofer provide?

The Audison Prima APS 8 D Subwoofer delivers a peak power of up to 500 watts and a continuous power handling of 250 watts. These power specifications make it particularly suitable for use in a sealed enclosure with a minimum volume of 7.5 liters. The design of the subwoofer allows it to deliver impressive performance in tight spaces without compromising sound quality. The construction from water-resistant, pressed paper, along with the special cone-dust cap-basket geometry, ensures a stable and powerful bass. The magnetic flux is enhanced by a high-density flux ferrite material.

What are the dimensions of the Audison Prima APS 8 D Subwoofer?

The Audison Prima APS 8 D Subwoofer has an overall size of 200 mm. The specific measurements are: A = 222 mm, B = 187 mm, C = 94.6 mm, and D = 79 mm. With an ultra-flat profile depth of only 79 mm, this subwoofer is flexible in installation, making it ideal for vehicles with limited space. The reduced installation dimensions allow for versatile mounting options, while the geometry of the cone-dust cap-basket construction supports long linear excursions. These dimensions create space for comprehensive bass reproduction without additional installations.

How is the Prima APS 8 D equipped for easy installation?

The Prima APS 8 D Subwoofer is equipped with push terminals that allow for quick and secure cable connections. This installation advantage combines with the shallow installation depth and vented openings in the basket, enabling mounting close to the enclosure's rear wall. The included elements, such as the steel grille and plastic gasket, contribute to easy fastening and additional stability. The massive motor assembly has been optimized using FEM modeling to provide maximum control at high power, significantly easing the installation experience.

What specific electroacoustic properties does the APS 8 D have?

The Audison Prima APS 8 D Subwoofer has unique electroacoustic properties. The nominal diameter is 173 mm and the displacement volume of the driver is 0.67. The DC resistance (Re) is 2.1 Ohms, while the resonance frequency (Fs) is at 30 Hz. The total equivalent volume Vas is specified as 25.5 liters, while the moving mass (Mms) is at 85 g. The mechanical compliance factor Cms is 0.3 mm/N. Furthermore, the Subwoofer achieves a sound pressure level (SPL) of 83.5 dB, and the inductance value (Le) is rated at 1.1 mH.

What materials and components enhance the performance of the Prima APS 8 D?

The Prima APS 8 D Subwoofer uses high-density flux ferrite materials for its magnet, allowing for improved efficiency and controlled sound performance. The water-resistant, pressed paper cone resists moisture, while its construction is optimized on the Klippel Scan Vibrometer to minimize distortion. The special cone-dust cap-basket geometry allows for long linear excursion and keeps the installation depth minimal. Additionally, the Subwoofer is supported by the massive motor assembly, which was developed through finite element modeling (FEM) for flawless performance under high load.

What impedance does the Prima APS 8 D Subwoofer have?

The Audison Prima APS 8 D Subwoofer has an impedance of 2 Ohms, making it ideal for use with various amplifier units. The lower impedance allows more current to flow through the voice coil, resulting in overall higher power and efficiency of the Subwoofer. This feature enables the Subwoofer to work with systems that require stronger bass support for a more powerful sound. Dual voice coil designs further expand the connections compatible with various amplifier configurations.

What Thiele Small parameters does the Audison Prima APS 8 D have?

The Audison Prima APS 8 D Subwoofer has specific Thiele-Small parameters that are crucial for enclosure design. With a Qes value of 0.46 and a Qms of 5.1, the total quality factor Qts is 0.44, describing the balance between electrical and mechanical losses. Xmax is specified at 8.8 mm and Xmech at 16.5 mm, which define the maximum excursion and the mechanical limit of the voice coil, respectively. These parameters are essential for optimally operating the Subwoofer within a closed enclosure and controlling resonance effects.

What compatibility exists with amplifiers for the Audison Prima APS 8 D?

The Prima APS 8 D is compatible with several amplifier models from the Audison range, including the AP8.9 bit (2 CH + 2 CH bridged), the AP5.9 bit (Sub CH), and AP4.9 bit/AP4 D (2 CH bridged). This allows for flexible configurations for various applications and offers high adaptability to existing Audison systems. The dual voice coil design enables multiple wiring options to achieve maximum output power and efficiency with these specific amplifiers. This compatibility maximizes the potential of the Subwoofer in a variety of audio networks.

What specific enclosure size is recommended for the Prima APS 8 D?

The Audison Prima APS 8 D Subwoofer is recommended for use in a sealed enclosure with a volume of at least 7.5 liters. This enclosure configuration is optimal for maximizing both bass levels and preserving sound clarity. The enclosure-specific recommendations help to properly tune the Subwoofer and avoid unwanted resonances. The specially designed geometry of the cone-dust cap-basket construction allows for powerful bass even in this compact size, making the Prima APS 8 D an excellent choice for space-constrained applications.

What is the weight of the Audison Prima APS 8 D?

The Audison Prima APS 8 D Subwoofer weighs a total of 3.1 kg. This moderate weight significantly facilitates handling and installation without compromising structural integrity or sound quality. Despite its relatively low weight, the Subwoofer, due to its massive motor assembly and solid enclosure construction, has the ability to deliver high performance and impressive bass with minimal space requirements. This weight specification is another indicator that the APS 8 D Subwoofer has been carefully designed to provide both performance and user-friendliness.
