Prima APK 570 by Audison

The APK 570 system is ideal for car models with doors designed to accommodate elliptical speakers with 5×7-inch woofers and AP 1 tweeters with special crossovers APCX TW 570. The crossovers are ultra-compact to facilitate installation and feature attenuation of the tweeter output level for excellent fine-tuning. The research and development team has optimized the electroacoustic parameters of the new woofers for installation in the car door, while retaining all the features of the Prima speakers, such as the compact size of the basket to ease installation. The mechanical cutoff of the cone dust cap system of the woofer ensures that they can be used without filters and maximizes efficiency, allowing them to be easily powered by any type of amplifier. The large voice coil ensures high power handling and flawless control even with the most aggressive dynamic transients. The dual Faston connectors with direct connection to the tweeter speed up the speaker connection and always ensure a perfect contact.

Audison Prima APK 570 Datasheet

Frequently Asked Questions about Prima APK 570


What size are the woofers and tweeters of the Prima APK 570 system?

The woofers in the Audison Prima APK 570 system have an elliptical size of 570 mm, while the tweeters have a diameter of 26 mm. These specific formats are designed to be compatible with the common doors of car models that can accommodate 5×7-inch woofers. The compact design of the woofers also allows for efficient installation in various vehicles. The size of the voice coil in the woofer is 32 mm, which ensures high load capacity and control, especially at low frequencies. The tweeters feature a voice coil with a diameter of 20 mm for precision in the high-frequency range.

What power does the Audison Prima APK 570 system offer?

The Audison Prima APK 570 system provides a peak power of 300 watts and an RMS power of 100 watts. These power values allow the system to deliver clear and distortion-free audio playback even at high volumes. The efficient use of the 4-ohm impedance ensures optimal power consumption and enhances the overall performance of the system. At the same time, the large voice coil in the woofer guarantees a high load capacity, which is necessary to produce the powerful and precise bass frequencies that are especially important during aggressive dynamic peaks.

How is the crossover of the Audison Prima APK 570 designed?

The crossover of the Audison Prima APK 570 is of the HP 6 dB/octave type at 3 kHz and features a specially ultra-compact design that allows for easy integration into various vehicles. It is equipped with a damping switch that allows the tweeter output level to be adjusted by 0 dB or +2 dB to optimize the response in the vehicle. These adjustment options are particularly useful for personalizing the sound output depending on the vehicle environment. The crossover is also designed to minimize potential connection errors, as it comes with quick connections.

How do the electroacoustic parameters affect the performance of the woofer in the Prima APK 570?

The electroacoustic parameters of the woofer in the Prima APK 570 are precisely optimized to deliver impressive performance. The nominal impedance (Re) is 3.1 Ohms, while the free air resonance frequency (Fs) of the woofer is set at 70 Hz to effectively reproduce deep bass tones. The mechanical quality (Qms) is 6.5 and the electrical quality (Qes) is 0.85, resulting in a Qts of 0.85. Vas, which represents the equivalent volume, is 10.5 liters, minimizing the impact of the enclosure on performance. The large copper wire of the voice coil also ensures excellent control.

What special features do the woofers of the Audison Prima APK 570 have?

The woofers of the Audison Prima APK 570 have several outstanding features. The paper cone, treated to be water-resistant and optimized with FEM technology, ensures robust and precise bass reproduction. The 'Triple Wave' surround profiling allows for maximum excursion linearity, providing smooth and distortion-free bass performance. A compact basket structure facilitates installation in OEM positions. Additionally, a wear- and scratch-resistant coating protects the basket. High-current quick connectors simplify the connection, while the 32 mm voice coil made of pure copper ensures high load capacity and fine control of low frequencies.

How does the AP 1 tweeter of the Prima APK 570 enhance the sound image in the vehicle?

The AP 1 tweeter of the Prima APK 570 is specifically designed to refine the sound image in the vehicle. With a 26 mm diaphragm diameter and a wide roll surround, it optimizes efficiency and reduces unwanted resonance frequencies. The acoustic lens of the tweeter compensates for discrete frequency response errors in the critical range of 10 kHz to 13 kHz, where challenging OEM setups often cause issues. The tweeter is also equipped with a 20 mm voice coil that ensures targeted and clear sound reproduction, especially at high frequencies.

What materials are used in the Prima APK 570?

The Audison Prima APK 570 uses high-quality materials to ensure the best sound performance. The woofer features a voice coil made of pure copper, known for its high load capacity and exceptional control. The cone is made of water-resistant treated paper, designed for robustness and precise sound reproduction. The mechanical shutdown of the dust cap system in the woofer is another constructive advantage that allows operation without a crossover. The basket is coated with a wear- and scratch-resistant finish, and the motor is secured with damping epoxy glue, increasing overall durability.

What is the load capacity of the woofers and tweeters in the Prima APK 570?

The maximum load capacity of the woofers in the Prima APK 570 system is 300 watts, while the continuous power handling is limited to 100 watts. This allows for distortion-free playback even during dynamic music reproduction. The tweeter, with a peak load capacity within its own performance range, enhances the sound profile with clear and precise highs. Notably, the large copper voice coils used in both the woofer and tweeter provide high load capacity and control, allowing them to be easily powered by various amplifiers.

What installation advantages does the Audison Prima APK 570 system offer?

The Audison Prima APK 570 system offers several installation advantages, especially for vehicles with limited door space. The compact design of the woofers facilitates installation in common OEM positions. The ultra-compact crossover adapts to spatial conditions without hindering installation. Additionally, high-current quick connectors speed up the installation by allowing electrical connections without specific tools. The handy size of the system and the protective coating of the basket ensure smooth and flexible integration into various car models that support 5×7-inch woofers.

What frequency ranges does the Prima APK 570 system cover?

The Audison Prima APK 570 system covers a wide frequency range from 55 Hz to 20 kHz, allowing for comprehensive sound adjustment from deep bass notes to high frequencies. The woofer is optimized to efficiently reproduce low frequencies, thanks to a large voice coil and a special cone and surround construction. The tweeter complements this range with its precise reproduction of high frequencies, made possible by the acoustic lens and optimized voice coil. This combination creates a complete and nuanced sound image.
