Häufige Fragen zum Prima AP 4

What technical features does the Audison Prima AP 4 have?

The Audison Prima AP 4 is a 4" (10cm) mid-bass speaker with a power handling of up to 120 W peak and 40 W continuous. The impedance is 4 Ohms, and the frequency response ranges from 80 Hz to 7.5 kHz. The 25 mm voice coil is made of pure copper, allowing for a balanced performance in the mid-high frequency range. The speaker has an SPL value of 91 dB and a Qts value of 1, ensuring high efficiency and effective sound reproduction. The water-resistant treated paper cone was developed using modern FEM simulation technology.

How does the integration of the Prima AP 4 into an audio system work?

The Audison Prima AP 4 can be easily integrated into OEM installation locations due to its shallow installation depth of only 41 mm. The TPU surround with the exclusive 'Triple Wave' profile ensures maximum excursion linearity and stable performance. Installation does not require a passive crossover, as the diaphragm has a calibrated mechanical low-pass cutoff frequency. These features make it suitable for both simple and more demanding audio systems without the need for additional filters. The installation is also protected by the compact, abrasion-resistant coated basket.

What speaker characteristics optimize the sound of the Prima AP 4?

With the Prima AP 4, the optimized diaphragm design provides a wide frequency response from 80 to 7.5 kHz, achieving excellent sound quality in both the high and low frequency ranges. The 3.2 Ohm voice coil and a BL value of 3.4 T•m contribute to the speaker's efficiency. A Qes value of 1.2 and a Qms of 7.6 support the balance between acoustic pressure and mechanical loss. The combination of these values ensures a harmonious audio tuning, suitable for both music lovers and everyday listening situations.

What does the water-resistant treatment of the diaphragm mean for the Prima AP 4?

The membrane of the Audison Prima AP 4 is treated to be water-repellent, which means it is protected against moisture and dripping water. This treatment increases durability and minimizes the risk of water damage, especially in humid environments or during inclement weather. The water-repellent layer ensures stable performance under various conditions and allows for reliable acoustics even with changing humidity levels. This design makes the Prima AP 4 particularly suitable for applications where high environmental resistance is required.

How does KLIPPEL technology affect the performance of the Prima AP 4?

The Audison Prima AP 4 utilizes KLIPPEL R&D Scan Vibrometer technology in its development to optimize membrane movement and thus sound precision. This technology helps minimize distortions in the sound profile and ensures a homogeneous sound image at different volume levels. Through this technology, the speaker achieves very precise and consistent performance across the entire frequency range. The use of KLIPPEL technology also improves the mechanical cutoff frequency, leading to clear and pure audio playback.

What installation tips are there for the Audison Prima AP 4?

The Prima AP 4 is characterized by its compact dimensions with a size profile of A 103 mm, B 93 mm, C 43 mm, and D 41 mm, allowing for easy installation in existing OEM mounting locations. Tip: The speaker has a shallower installation depth, making it ideal for limited mounting depths. Although no specific car brands are mentioned in the product description, the Prima AP 4 can be integrated into many common car models due to its dimensions and features. Make sure that the installation location has an appropriate opening to fully utilize the speaker's efficiency.

What materials are used in the Prima AP 4 and how do they affect the sound?

The Audison Prima AP 4 uses a 25-mm voice coil made of pure copper, providing excellent conductivity and low distortion. The paper cone, treated to be water-resistant, supports clear midtones and powerful bass. The thermoplastic polyurethane (TPU) used for the surround offers flexibility and durability while ensuring consistent sound characteristics. These high-quality materials contribute to the acoustic quality and longevity of the speaker, making it well-suited for both demanding musical experiences and everyday use.

How effective is the Prima AP 4 in terms of frequency response?

The Prima AP 4 impresses with an extremely wide frequency response of 80 Hz to 7.5 kHz. This capability allows it to reproduce both deep bass and high clear tones evenly. The specially designed diaphragm with FEM simulation technology supports the reproduction of frequency-specific nuances. The high efficiency of 91 dB helps to utilize this bandwidth efficiently, even at lower amplifier power levels. This means that both pop tracks and orchestral works can be reproduced in detail and vibrantly.

What are the load limits of the Audison Prima AP 4?

The Audison Prima AP 4 has a peak power handling of 120 W and a continuous power handling of 40 W, allowing it to handle high volumes without sacrificing sound quality. These power handling values indicate the maximum performance the speaker can process without damage. Ideal for anyone seeking a powerful sound experience. Especially during intense use, the continuous power handling is crucial as it reflects the daily peak performance the speaker can handle, while the peak power handling can cover short-term, higher power consumption.

What sound characteristics result from the Thiele-Small parameters of the Prima AP 4?

The Thiele-Small parameters of the Prima AP 4, such as Fs of 125 Hz and Vas of 1.5 l, provide insight into the bass reproduction performance and efficiency of the speaker. The Qts value of 1 indicates a well-damped resonance and optimal combination of Qes (1.2) and Qms (7.6). These parameters directly affect the speaker tuning in the enclosure and determine the low-frequency dynamics. The low mechanical loss and controlled elasticity lead to precise and clearly defined bass reproduction, ideal for dynamic musical pieces.
