Frequently Asked Questions about Inside ISUB-BMW-4


What is the power of the Focal ISUB-BMW-4 Subwoofer?

The Focal ISUB-BMW-4 Subwoofer has a nominal power of 90 watts and a maximum power of 180 watts. This means it is capable of performing well both in regular operation and in more intense audio scenarios. The nominal power of 90 watts ensures that the subwoofer continuously delivers a stable sound, while the peak power of 180 watts allows for higher volumes when needed, without compromising the integrity of the device. These power specifications are ideal for music lovers seeking quality sound support.

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

The sensitivity of the Focal ISUB-BMW-4 Subwoofer is 86 dB. A value in this range means that the subwoofer operates efficiently and can produce a relatively good volume with lower power consumption. This technical specification is particularly important for integration into vehicles, as it indicates how much power is needed to achieve sufficient volume. The sensitivity value thus supports the selection of the appropriate amplifier power to ensure optimal playback quality.

What frequencies can the Focal ISUB-BMW-4 process?

The frequency range of the Focal ISUB-BMW-4 Subwoofer is between 35 Hz and 200 Hz. This means that the subwoofer is specifically designed for reproducing low tones and is capable of enhancing the deep bass that is often not optimally reproduced by audio systems. Sub-frequencies at 35 Hz provide a powerful deep experience and are important for the high-quality playback of modern music. At the same time, the upper limit of 200 Hz ensures that the subwoofer remains balanced and does not encroach into the mid-range of other speakers, minimizing distortion.

What is the design of the Focal ISUB-BMW-4 cone?

The cone of the Focal ISUB-BMW-4 Subwoofer is made of paper, while the surround is made of butyl. Paper cones are known for their lightweight and ability to produce precise sounds. Butyl, on the other hand, as a material for the surround, is extremely elastic and durable, making the subwoofer resistant to environmental factors and heavily used situations. These materials combined offer high damage resistance and ensure that the subwoofer can operate stably and efficiently under various conditions.

What are the technical details of the voice coil of the Focal ISUB-BMW-4?

The voice coil of the Focal ISUB-BMW-4 has a diameter of 50 mm, which ensures high load capacity. The former is made of aluminum, known for its good heat dissipation, and is crucial for the thermal stability of the subwoofer. The wire of the voice coil is made of copper, which is characterized by excellent electrical conductivity, thus ensuring the efficiency of the coil. Additionally, the layers of the voice coil consist of two layers, which increases its durability and contributes to the improved overall performance of the subwoofer.

Which vehicles is the Focal ISUB-BMW-4 Subwoofer compatible with?

Since the Focal ISUB-BMW-4 is specifically designated as a BMW Subwoofer, it is designed for BMW vehicles. With its specially tuned dimensions, it offers seamless integration into the original installation locations of many BMW models. If you have a different vehicle model and are planning the installation, it is important to compare the exact dimensions of the installation space with the product specifications. Accurate measuring and considering the information in the vehicle manual are crucial. It is recommended to clarify compatibility and installation with professionals.

What impedance does the Focal ISUB-BMW-4 have?

The Focal ISUB-BMW-4 Subwoofer has a nominal impedance of 4 Ohm. This impedance is ideal for use in vehicle audio systems, as it provides a good balance between power consumption and output. Additionally, a DC resistance of 4 Ohm is specified, which ensures consistent performance. 4-Ohm impedances are also advantageous, as they can be integrated into most common amplifier configurations without issues. When connecting to existing systems, it is crucial to check compatibility with the amplifiers present to ensure optimal sound quality.

How to optimally install the Focal ISUB-BMW-4?

When installing the Focal ISUB-BMW-4 Subwoofer, it is important to consider the technical specifications such as dimensions and electrical connections. The subwoofer should be properly mounted in the designated installation frame, usually in the trunk or in the spare wheel well of BMW models. Correct wiring with the vehicle amplifier is essential to ensure stable and powerful sound reproduction. It is advisable to follow the installation instructions from Focal closely, also to make individual adjustments and achieve maximum performance.

What materials are used in the construction of the Focal ISUB-BMW-4?

The Focal ISUB-BMW-4 Subwoofer uses high-quality materials. The cone is made of paper, known for its clear and natural sound. The surround is made of butyl, which is characterized by long durability and resilience. The voice coil former is made of aluminum, ideal for heat dissipation, while the wire is made of copper, valued for its high electrical conductivity. This choice of materials ensures that the subwoofer meets the high demands in the vehicle interior both acoustically and mechanically.

What role does the weight of the Focal ISUB-BMW-4 play?

The Focal ISUB-BMW-4 has a net weight of 970 grams. This lightness not only simplifies the installation process in the vehicle but also minimizes the impact on the overall weight of the vehicle, which is particularly of interest to sports car enthusiasts. Despite its low weight, there are no compromises in stability and sound quality, as each component has been carefully selected to ensure optimal performance.
