Frequently Asked Questions about Inside ISUB-BMW-4


What is the nominal power of the Inside ISUB-BMW-4?

The Inside ISUB-BMW-4 from Focal has a nominal power of 90 watts. This power rating indicates how much energy the BMW Subwoofer can continuously handle without overheating or sound distortion. Especially during longer listening sessions and at high volumes, the nominal power of 90 watts is an important aspect to ensure consistent and clear audio playback.

What is the maximum power of the Inside ISUB-BMW-4 Subwoofer?

The maximum power of the Inside ISUB-BMW-4 Subwoofer is 180 watts. This is the peak power that the Subwoofer can handle for short periods to achieve maximum volume levels. For an optimal listening experience, it is important that this peak power is only temporarily utilized to maintain the integrity of the device.

What is the sensitivity of the Inside ISUB-BMW-4?

The Inside ISUB-BMW-4 from Focal has a sensitivity of 86 dB. This figure indicates how efficiently the Subwoofer converts sound in relation to the input power. A higher dB value means that the Subwoofer requires less power to produce the same volume. With a sensitivity of 86 dB, it is ensured that good volume can be achieved even at moderate power.

What is the significance of the nominal impedance of 4 ohms in the Inside ISUB-BMW-4?

The nominal impedance of 4 ohms in the Inside ISUB-BMW-4 is crucial for compatibility with amplifiers. Impedance describes the electrical resistance and affects how much current the Subwoofer draws from the amplifier. At 4 ohms, the Subwoofer can efficiently work with typical amplifiers and ensure stable audio performance without overload.

What materials are used in the Inside ISUB-BMW-4?

The Inside ISUB-BMW-4 uses a cone made of paper and a surround made of butyl. Paper cones are known for their lightness and stiffness, allowing for quick response times and low distortion. The butyl surround ensures excellent durability and flexibility at high excursions. This combination of materials contributes to a balanced and dynamic sound profile.

What are the dimensions and weight of the Inside ISUB-BMW-4?

The Subwoofer Inside ISUB-BMW-4 has a net weight of 970g. Although no explicit dimensions are provided, this weight is relevant for installation and handling in the vehicle. It allows for easy integration without excessive strain on the vehicle structure. When installing, it is important to consider the weight of the subwoofer to ensure proper mounting.

What frequency response does the Focal Inside ISUB-BMW-4 offer?

The frequency range of the Inside ISUB-BMW-4 extends from 35 to 200 Hz. This bandwidth allows for deep bass and lower midrange to be reproduced accurately and powerfully. As a result, particularly low frequencies in music tracks are impressively enhanced, immersing the listener in an engaging sound experience. Frequency response is a crucial factor for sound dynamics in the car.

How is the voice coil in the Inside ISUB-BMW-4 constructed?

The Inside ISUB-BMW-4 is equipped with an aluminum former voice coil that has a diameter of 50 mm and is wrapped with double copper layers. This construction optimizes the thermal efficiency and durability of the subwoofer during intense use. The materials used, especially the aluminum former, ensure improved heat dissipation, leading to a stable and distortion-free sound profile.

How does the DC resistance affect the Inside ISUB-BMW-4?

In the Focal Inside ISUB-BMW-4, the DC resistance is 4 Ohm. This figure is directly linked to the nominal impedance and affects how much current flows through the voice coil. A DC resistance of 4 Ohm ensures efficient power intake and guarantees that the subwoofer is optimally compatible with common amplifiers. This contributes to stable sound performance, even at high volumes.

What compatibility does the Inside ISUB-BMW-4 have regarding BMW models?

The Inside ISUB-BMW-4 is specifically designed for integration into BMW models. Technical adjustments such as the specific nominal impedance of 4 Ohm, as well as the tailored shape and material selection, allow for seamless installation in the pre-configured subwoofer factories of BMW vehicles. This eliminates the need for major modifications while ensuring top-notch sound reproduction in line with BMW audio standards.
