Technical performance: Neodymium magnet for unprecedented control

Equipped with a neodymium magnet, the subwoofer impresses with outstanding power and control. Neodymium magnets are significantly more powerful than their ferrite counterparts, meaning they better compensate for the suboptimal frequency response at lower volumes. The APBMW S8-4.2 strikes an elegant balance between depth and clarity in the bass frequency range, which is evident in its frequency response from 40 to 500 Hz.

Size and compatibility: Perfect for BMWs and Mini models

With dimensions of 217 mm (A) and an installation depth of 55.2 mm (D), the subwoofer is optimally adapted to the OEM installation position under the front seats of BMWs. The special BMW adaptation ensures that sound quality and bass reproduction are maximized even without major structural modifications. Complemented by its low weight of just 1.21 kg, it fits seamlessly into specific models of the BMW 1, 2, 3, 4, 5, 6, and 7 series, as well as BMW Mini vehicles.

Unique design: housing material and membrane

The subwoofer utilizes a precision-engineered plastic chassis and a molded paper cone. This material combination provides an excellent stiffness-to-weight ratio and reduces unwanted resonances and distortion. Therefore, the cone's vibration behavior is optimally aligned for precise bass reproduction.

Thiele-Small Parameters: Performance Drivers in Perfection

The technically ambitious design of the Prima APBMW S8-4.2 is reflected in its excellent Thiele-Small parameters: a Vas of 21 liters and a resonant frequency (Fs) of 40 Hz. The moving mass (Mms) is comparatively low at 43 g, enabling fast and precise response to various frequencies. Together with the overall quality factor (Qts) of 0.65, this creates an optimal balance between electroacoustic efficiency and bass resonance.

Displacement volume and membrane area: Maximized bass performance in a compact design

The driver displacement is 1.2 liters, while the diaphragm area is 198.6 cm². This combination contributes to the effective conversion of electrical signals into acoustic energy without increasing the overall footprint. An Xmax of 7 mm and an Xmech of 10 mm ensure sufficient excursion, resulting in voluminous, undistorted low frequencies, even at higher volumes and under extreme conditions.

Limited installation options with the OEM seals

Another feature is the inclusion of two 5 mm thick OEM gaskets, ensuring seamless integration into the existing installation position. This customization option not only ensures high efficiency but also contributes to optimizing sound quality by fully utilizing the acoustic capabilities of the installation environment.

Bass amplification through powerful drive: 38 mm copper coil

The 38 mm voice coil, wound on an aluminum core, offers excellent power dissipation and thermal stability. This increases the power handling under operating conditions where continuous and intense sound tuning is required. A copper coil is known for its excellent electrical conductivity, thus offering an optimal balance between power and efficiency.

Low-maintenance properties and excellent workmanship

With high-quality materials ensuring excellent durability, the subwoofer requires little maintenance. The durable rubber surround material minimizes distortion at high volumes and ensures consistent resonance control. All this in a product precisely designed for BMW vehicles, promising you the ultimate acoustic experience.

2-ohm configuration for maximum flexibility in use

This 2-ohm configuration offers remarkable advantages in an actively separated system, especially when used in combination with the Audison AP 8.9 bit. The configuration allows for maximum power extraction and efficient signal processing without compromising sound quality. This is especially useful when you need high power reserves to achieve massive sonic dynamics.

Cone and surround for flawless sound

The pressed paper cone combined with the rubber surround provides excellent control of bass vibrations. This design ensures that the Prima APBMW S8-4.2 delivers deep, punchy frequencies that remain clear and clean even at high volumes. This construction minimizes distortion and transforms every musical journey into a first-class acoustic experience. Are you interested in the Audison Prima APBMW S8-4.2 or looking for expert advice?
