    Frequently Asked Questions about Inside ISUB BMW 8

    What is the power output of the Focal Inside ISUB BMW 8 Subwoofer?

    The Focal Inside ISUB BMW 8 Subwoofer offers a nominal power of 90 watts and reaches a maximum power of 180 watts, making it a powerful addition to your sound system. With a sensitivity of 89 dB, it is designed to deliver impressive volume even at lower input power. If you enjoy listening to music at high volumes, you will benefit from its high performance, as the subwoofer provides a consistent and dynamic sound across the entire frequency range of 35 to 200 Hz. The combination of high power and wide frequency response ensures an excellent sound experience.

    What is the frequency response of the Focal Subwoofer for BMW?

    The Focal Subwoofer for BMW, known as the Inside ISUB BMW 8, has a frequency response of 35–200 Hz. This allows for powerful bass reproduction that accurately covers both deep bass and upper bass frequencies. If you prefer music genres that thrive on strong bass, such as hip-hop or electronic music, the subwoofer will meet your needs. The paper cone and butyl surround work together to provide responsive and precise bass reproduction. With the extensive frequency range, you get detailed low-frequency playback.

    What materials are used in the Focal BMW Subwoofer?

    The Focal BMW Subwoofer features a paper cone that provides a lightweight yet stiff diaphragm, enhancing responsiveness. The surround material is made of butyl, an extremely durable rubber that effectively dampens vibrations and ensures longevity. The voice coil former is made of aluminum and has two copper layers, allowing for better heat dissipation and high power stability. This choice of materials combines robust properties with optimized sound quality and is essential for accurate low-frequency reproduction.

    What are the technical parameters of the Focal Inside ISUB BMW 8?

    The Focal Inside ISUB BMW 8 features versatile technical parameters such as a nominal impedance of 8 Ω, making it excellent for integration into existing audio systems. The DC resistance is 6.6 Ω. The resonance frequency Fs is 40 Hz, while the moving mass Mms weighs 40 g. The compliance Cms is 0.3 mm/N, indicating the flexibility of the diaphragm. The mechanical loss factor Qms is 3. A BxL value of 9.2 N/A and a radiation factor Sd of 213 cm² contribute to the efficiency and overall optimization of the subwoofer.

    What Thiele-Small parameters are specified for the Focal Subwoofer?

    The Focal Subwoofer, Inside ISUB BMW 8, offers specific Thiele-Small parameters that are essential for sound optimization. Qts is 0.65, which, along with Qes of 0.9, shows that the subwoofer is optimized for electroacoustic efficiency. A Vas value of 18 liters indicates the equivalent volume. The Xmax of 6.5 mm describes the maximum linear excursion of the diaphragm, important for loud and distortion-free playback. Particularly helpful is the SPL value of 84 dB, which describes the expected volume under standard conditions. These parameters are crucial for understanding performance in an enclosure.

    How is the compatibility and installation of the Focal Subwoofer in the vehicle?

    When installing the Focal Subwoofer, Inside ISUB BMW 8, compatibility with various vehicles is a central aspect. Due to the specific dimensions and parameters, special attention must be paid to integration into BMW models. Before installation, it must be ensured that the available installation space matches the subwoofer dimensions. Thanks to the compact design with a net weight of only 990 g, installation in tight spaces can be realized. Be sure to consider the technical specifications, such as the nominal impedance of 8 Ω, when integrating into the existing audio system to ensure sound optimization.

    How does the voice coil affect the performance of the Focal Subwoofer?

    In the Focal Inside ISUB BMW 8 Subwoofer, the voice coil, consisting of an aluminum former and copper wire in two layers, has a significant impact on performance. The voice coil diameter of 50 mm ensures effective control of diaphragm movement and allows handling of higher power without overheating. Aluminum as a material provides an optimal combination of high conductivity and rapid cooling behavior. This construction ensures that the subwoofer operates consistently and reliably, even at higher volumes, achieving bulletproof precision in playback.

    What influence does the surround material butyl have on the sound of the subwoofer?

    The butyl surround material in the Focal Inside ISUB BMW 8 has a significant impact on the sound quality of the subwoofer. Butyl is known for its high elasticity and durability, making the subwoofer particularly resistant to mechanical wear. This results in excellent damping of unwanted vibrations, ensuring clean bass reproduction. In environments with varying temperature and humidity conditions, butyl remains dimensionally stable, keeping the playback quality consistent and minimizing distortion. Thus, the sound comes across as denser and fuller.

    What effects does the sensitivity of 89 dB have on the Focal subwoofer?

    The sensitivity of 89 dB of the Focal subwoofer, Inside ISUB BMW 8, means that it can produce high volume even with lower power input. This is ideal for reducing the load on the amplifier, which in turn improves the efficiency of the system. High sensitivity allows the subwoofer to unleash maximum power in conjunction with various amplifier specifications. Especially in vehicles that rely on limited amplifier power, a sensitivity of 89 dB provides the advantage of delivering powerful bass without the amplifier having to operate continuously in the high-performance range.

    How does the paper cone optimize sound quality in the subwoofer?

    The paper cone in the Focal Inside ISUB BMW 8 subwoofer significantly contributes to improving sound quality. Paper is a lightweight material that allows for quick and precise response of the diaphragm, achieving clear and accurate bass reproduction. This material property ensures that the subwoofer remains consistent at both low and high volumes without showing significant distortion. The effectiveness increases with the use of butyl surround, as this stabilizes the material and further refines the playback. Overall, the paper cone greatly enhances dynamics and sound fidelity.
