The water-repellent press paper membrane of the Prima APBMW K4M midrange driver ensures a natural sound free from unwanted plastic resonances. This is particularly beneficial in a vehicle environment, where moisture is a common challenge. Especially if you enjoy listening to music loudly while wanting to experience clear and precise sound, this special membrane structure provides an optimized listening experience. Additionally, the water-repellent property enhances the durability of your speaker system, protects against environmental influences, and ensures long-lasting sound quality. The speaker remains stable and functional even in high humidity.

What specific performance data does the Prima APBMW K4M have?

The Prima APBMW K4M offers a peak power of 100 watts and a continuous power handling of 50 watts, providing a remarkably powerful listening experience. The Crossover operates with a high-pass cutoff in the range of 150-200 Hz and offers a Hi-Pass: 6 KHz @ 6dB/Oct. The woofer shows a sensitivity of 89 dB at an impedance of 4 ohms, making it ideal for use in vehicles that require high output power with optimal energy operation. These parameters, especially the peak power, make it a powerful addition to your vehicle.

What are the Thiele-Small parameters for the woofer of the Audison Prima APBMW K4M?

The Thiele-Small parameters for the woofer of the Prima APBMW K4M include a Re value of 3.3 ohms, a resonance frequency (Fs) of 90 Hz, and an equivalent volume (Vas) of 1.8 liters. Furthermore, the moving mass (Mms) is 6.4 g, the compliance (Cms) is 0.5, and the force factor (Bxl) is 4.8. With a total Q factor (Qts) of 0.48, the woofer shows a balanced performance between power and compliance, ideal for detailed audio reproduction. Qms is at 8.9, while the magnet system has also been optimized to deliver an impressive sensitivity of 88 dB.

How does the neodymium magnet of the Prima APBMW K4M affect sound performance?

The neodymium magnet in the Prima APBMW K4M maximizes performance while minimizing weight and mass, which is particularly advantageous in vehicles. Neodymium is known for its high magnetic strength, allowing for more precise movement of the speaker diaphragm, resulting in a more dynamic auditory experience. The emphasis on clarity and precision in every frequency range, from deep bass to high frequencies, is enhanced by the magnetic force. This technical component is invaluable for users who need a detailed and powerful soundstage in their car.

What installation options does the Prima APBMW K4M set offer for BMW models?

The Prima APBMW K4M set is specifically designed for a variety of BMW models such as the BMW 1 Series, 2 Series, 3 Series, 4 Series, 5 Series, 6 Series, 7 Series, as well as Mini models. With plug-and-play connections and a supplied 30 cm extension, the system can be integrated with minimal effort. The aluminum die-cast basket and the Tetolon tweeter are tailored to OEM fixtures, allowing for easy installation. Due to specific compatibilities, such as with the BMW 3 Series F30 center and top Hi-Fi midrange and parcel shelf, the speakers can be easily integrated into existing systems. The comprehensive installation solution offers flexibility and significantly simplifies the mounting process.

What functions does the crossover in the Prima APBMW K4M have?

The crossover in the Prima APBMW K4M is equipped with high-pass and band-pass filters that separate frequencies at 6 kHz @ 6dB/Oct.

How does the Tetolon tweeter of the Prima APBMW K4M contribute to sound quality?

The 25 mm Tetolon tweeter of the Prima APBMW K4M is optimized for reproducing high-precision and clear highs. This component was developed using FEM simulations to achieve an ideal radiation characteristic, creating a comprehensive soundstage. Tetolon is a special material known for providing balanced and smooth frequency reproduction. In conjunction with the flexible adjustment level of -3 dB to 0 dB for different acoustic requirements, the tweeter allows for personalized audio playback. These features make the tweeter an essential component for enthusiasts expecting the highest sound fidelity in the vehicle interior.

What is the function of the aluminum die-cast basket in the Prima APBMW K4M?

The aluminum die-cast basket of the Prima APBMW K4M serves multiple purposes: it provides a stable and resonance-free structure that enhances sound quality by minimizing vibrations. Aluminum is lightweight yet robust, which helps reduce distortion at high volumes. Additionally, the die-cast basket is specifically made for BMW models, ensuring a precise fit and easy installation.
