    Häufige Fragen zum Inside ISUB BMW 8

    What is the rated power of the Focal ISUB BMW 8 Subwoofer?

    The Focal ISUB BMW 8 offers a rated power of 90 watts. This means it can continuously deliver 90 watts of power without distortion, ensuring a clean and clear sound. The maximum power is 180 watts, which means the Subwoofer can also operate at higher volumes without sound loss. These power specifications make the ISUB BMW 8 ideal for use in BMW vehicles seeking a high-quality audio solution.

    How sensitive is the Focal ISUB BMW 8?

    With a sensitivity of 89 dB, the Focal ISUB BMW 8 is designed to operate efficiently even with lower amplifier power. Sensitivity indicates how much sound pressure in decibels the Subwoofer can produce at a power of one watt. A sensitivity of 89 dB means the Subwoofer is capable of delivering strong bass without requiring a particularly powerful amplifier. This is ideal for integration into existing audio systems without much effort.

    What are the dimensions of the Focal ISUB BMW 8 Subwoofer?

    The Focal ISUB BMW 8 has a diaphragm area of 213 cm², which is crucial for bass reproduction. The diameter of the voice coil is 50 mm, also known as 2", which benefits the stability of sound at high volumes. These dimensions ensure that the Subwoofer can be perfectly integrated into specific BMW models. With a weight of 990 g, the Subwoofer is also light enough not to affect the vehicle dynamics while still providing sufficiently deep bass reproduction.

    What materials are used in the Focal ISUB BMW 8?

    The cone of the Focal ISUB BMW 8 is made of high-quality paper, known in the audio world for its excellent sound quality and lightness. This allows for a quick and precise response to sound waves. The surround material is made of butyl, also known for its durability and ability to dampen vibrations. The former of the voice coil, made of aluminum, increases thermal resilience and ensures stable performance even under intense use. This combination of materials supports the high sound quality of the Subwoofer.

    What are the Thiele-Small parameters of the Focal ISUB BMW 8?

    The Thiele-Small parameters of the Focal ISUB BMW 8 are crucial for understanding its performance. The DC resistance (Rdc) is 6.6 Ω, Fs is 40 Hz, which indicates the resonance frequency of the Subwoofer and defines its deep bass range. The moving mass (Mms) is 40 g and the compliance of the suspension (Cms) is 0.3 mm/N. The equivalent volume Vas is 18 l, and the Q factors are Qts 0.65, Qes 0.9, and Qms 3. These parameters significantly influence the bass reproduction and response behavior of the Subwoofer in various enclosures.

    What sound quality does the Focal ISUB BMW 8 offer through its frequency response?

    The frequency response of the Focal ISUB BMW 8 ranges from 35 Hz to 200 Hz, covering a wide range of low frequencies that are crucial for rich bass reproduction. This means that the Subwoofer is capable of clearly reproducing both deep bass and mid-range frequencies. The combination of these frequencies provides a full, powerful sound that enhances the listening experience in the car. Especially for discerning music lovers, this Subwoofer offers a high-quality extension of the existing sound system.

    How does the nominal impedance of the Focal ISUB BMW 8 affect the sound?

    With a nominal impedance of 8 Ohms, the Focal ISUB BMW 8 is designed to be used in many audio systems. The impedance affects compatibility with Amplifiers. A lower impedance means that the Amplifier can deliver more power, resulting in louder playback. When installed in car systems, the 8 Ohm impedance allows for flexible adjustment options to maximize performance from the audio system without sacrificing sound quality.

    What is the maximum power of the Focal ISUB BMW 8?

    The Focal ISUB BMW 8 reaches a maximum power of 180 Watts. This specification is crucial for determining the peak load capacity of the Subwoofer. During deep bass lines or extreme music peaks, the Subwoofer can reach this value without damage. This ensures that even with demanding music pieces or higher volumes, a rich and precise sound without distortion is guaranteed. This maximum power is important for understanding the performance limits and optimal integration into the audio system.

    What is the weight of the Focal ISUB BMW 8 and why is it important?

    The Focal ISUB BMW 8 weighs 990 grams, which is relatively light for a Subwoofer in this power class. This low weight is advantageous as it allows for easy integration into the vehicle without significantly affecting its overall weight. This feature is particularly beneficial for vehicles where weight plays a crucial role. A lower weight can also improve resonance characteristics, as it puts less strain on the enclosure and minimizes vibrations, ultimately contributing to better sound quality.

    How do you install the Focal ISUB BMW 8 Subwoofer in the car?

    Installing the Focal ISUB BMW 8 Subwoofer requires precise knowledge of the mechanical dimensions. With a diaphragm area of 213 cm² and a sound pressure level of 84 dB SPL, suitable placement in the vehicle is necessary to ensure optimal bass reproduction. During installation, existing speaker interfaces from BMW should be used to avoid compatibility issues. It is important to ensure that the Subwoofer is securely mounted to avoid compromising sound quality and to minimize vibrations.
