Frequency response of the Focal subwoofer from 35-200 Hz: Deep bass, clear treble

The frequency range of 35 to 200 Hz makes this BMW subwoofer ideal for virtually all music genres. The lower frequency of 35 Hz means you'll experience deep bass, adding impressive depth to your car audio system. The upper frequency of 200 Hz allows for clear, undistorted mid-range reproduction. A slight increase in the upper frequency range could offer the potential for extended mid-frequency reproduction without losing the bass punch needed for deep beats.

Sensitivity of 86 dB: Optimal tunability for maximum sound

With a sensitivity of 86 dB, the Focal subwoofer is optimally tuned to achieve impressive volume even at low amplifier power levels. Higher sensitivity values ​​could increase efficiency, but this can often come at the expense of bass quality. Here, the ISUB-BMW-4 strikes the perfect balance between richness and efficiency. Typically, values ​​above 85 dB are considered efficient, with values ​​above 90 dB often optimized for even quieter listening environments.

Paper cone and butyl surround: materials for long-lasting sound

The paper cone and butyl surround are essential features that contribute to the subwoofer's sound quality. Paper cones are known for their lightweight yet rigid structure, which allows for rapid response to audio signals. This results in a precise and clean sound. The butyl surround provides lasting flexibility and damping, ideal for minimizing unwanted vibrations and distortion. Switching to a different material could drastically alter the sound, often at the expense of precision and resonance.

4-ohm DC resistor for efficient power handling

The 4-ohm DC resistance is ideal for efficient use of electrical power in BMW systems. A 4-ohm resistor is common in car hi-fi technology and ensures that neither energy efficiency nor sound dispersion are compromised. Reducing this value could cause the subwoofer to draw more current, which could lead to overheating in extreme cases, while a higher resistance could place greater strain on the amplifier.

VC diameter and copper wire: Optimized vibration properties

With a voice coil diameter of 50 mm, the subwoofer offers excellent control over the cone movements. Copper as the wire material ensures ideal conductivity and heat dissipation. The aluminum former, combined with the copper coating, ensures durability under variable temperature conditions and enables precise, rapid movements, which are crucial for sound quality. Larger diameters could theoretically offer greater stability, but usually come with increased weight and inertia.

Net weight of 970g: Lightweight subwoofer for easy installation

The net weight of 970g makes the Focal Inside ISUB-BMW-4 one of the lighter subwoofers on the market, simplifying installation and maintaining the vehicle's bulk. This lightness also facilitates integration and reduces potential vibration issues typically associated with heavier systems. However, a lower weight would be critical to acoustic performance, as it would significantly affect the vibrating mass and thus the bass pressure.

Aluminum former and dual-layer copper winding for robustness and performance

The use of aluminum in the former underscores Focal's commitment to high-quality materials to promote resistance to thermal expansion and contraction. The two-layer copper winding offers both sensitivity and power, ideal for dynamic audio reproduction. Other configurations could either optimize heat treatment or reduce the moment of inertia, thus producing different acoustic results that deviate from the original design intent.

Connections and installation: Suitable solution for BMW vehicles

With the specific connection options, installing your new subwoofer in BMW vehicles is incredibly easy. The precise fit supports seamless integration, which is specifically tailored for brand compatibility. Failure to comply with the connectivity specifications could compromise performance, which is why Masori offers specialized on-site installation in Frankfurt (Oder) .
