High frequency reproduction thanks to 25 mm Tetolon tweeter

The 25 mm Tetolon tweeter in Audison's Prima APBMW K4E delivers exceptionally clear and detailed high-frequency reproduction. The optimized dispersion pattern, achieved through FEM simulations, ensures a linear frequency response, which is crucial for the detailed treble reproduction. At frequencies from 90 Hz to 23 kHz, the APBMW K4E tweeter can cover a wide spectrum, resulting in natural sound reproduction. A smaller tweeter or lower power might result in less precise treble reproduction.

Efficient energy conversion with 25 mm midrange voice coil

The midrange voice coil of the Audison Prima APBMW K4E has a diameter of 25 mm, resulting in efficient conversion of electrical energy into acoustic energy. Thanks to the use of fiberglass material, the voice coil guarantees high power handling and rigidity, resulting in distortion-free sound reproduction. The voice coil also contributes to the speaker's resistance to thermal stress. A smaller voice coil could result in inefficient energy conversion and lead to power loss.

Installation accessories specifically for BMW compatibility

Included accessories, such as the APBMW A4E, significantly simplify speaker installation in BMW models with non-standard mounting brackets. This plug-and-play solution allows for easy installation without the need for modification or adapter-related issues. An additional plus point is the 30 cm extension kit, which increases installation flexibility. These features are crucial for BMW owners seeking straightforward upgradeability of their audio systems.

Neodymium magnet for maximized performance and minimized weight

The neodymium magnet in the Audison Prima APBMW K4E improves the speaker's overall performance while minimizing weight. Measuring 50 x 29 x 3 mm, the magnet enables strong magnetic field performance in a compact size. Neodymium magnets are known to be more efficient than conventional ferrite magnets, resulting in significant energy savings. A smaller magnet would have compromised energy conversion and potentially reduced the speaker's efficiency.

Adjustable tweeter level for individual sound control

The Audison Prima APBMW K4E features tweeter level adjustment, which can be set to either -3 or 0 dB. This feature allows the treble to be adjusted to suit individual listener preferences and the vehicle's acoustic environment. The adjustable crossover frequency at 6 kHz ensures that only the desired frequencies are passed to the respective speakers. Without these adjustment options, there is a risk of less flexible sound reproduction in the vehicle.

Optimized woofer performance through Thiele-Small parameters

The Thiele-Small parameters of the Prima APBMW K4E woofer, including an Re of 3.3 ohms, an F of 90 Hz, a Vas of 1.8 liters, an Mms of 6.3 g, a Cms of 0.5 mm/N, a Qts of 0.48, and a Qms of 8.2, provide comprehensive technological insights. In particular, the low Qts value of 0.48 indicates precise control of the cone movements, which is important for tight bass response. A higher Qts could result in a less precise bass response.

Durable woofer cone made of waterproof, pressed paper

The primary woofer of the Audison Prima APBMW K4E uses a water-resistant pressed paper cone, ensuring natural mid-frequency reproduction without plastic resonances. This design choice supports durability in changing environmental conditions. A lower-quality material would increase the risk of vibrating resonances and a reduced cone lifespan, especially in humid environments.

High sensitivity for efficient signal conversion

With a sensitivity of 89 dB, the Audison Prima APBMW K4E ensures efficient conversion of amplifier signal to sound pressure. A higher sensitivity value means less amplifier power is required to achieve the same volume, resulting in more economical operation. A lower sensitivity value would require more power to achieve the same volume, which could reduce efficiency.

Precise Xmax for minimal distortion at high volume

The woofer's Xmax value of 0.5 mm allows for precise control of the voice coil within a single sweep. This measure of maximum linear travel ensures minimal distortion even at high volumes. A higher Xmax offers the advantage of reproducing low bass frequencies without audible distortion. Lack of this precision could result in increased distortion, especially at high volumes.

Lightweight and durable construction materials for high-quality sound

With a weight of just 0.46 kg for the woofer and 0.06 kg for the tweeter, Audison has opted for lightweight construction with the Prima APBMW K4E without compromising on sound quality. Lightweight speakers are easier to install and have a minimal impact on the overall weight of the vehicle. A higher weight could result in unnecessary stress and complicate the installation process, especially in vehicle-specific installation situations.
