Frequently Asked Questions about Prima AP 6.5 Ohm2

What are the main technical features of the Prima AP 6.5 Ohm2?

The Audison Prima AP 6.5 Ohm2 is a 6.5-inch mid-bass speaker with a nominal impedance of 2 Ohms, designed to fully utilize the power of the AP8.9-Bit Amplifier. Key features include a peak power of 210 W, a 25 mm voice coil for high efficiency, and a sound pressure level of 95 dB. The speaker offers a frequency range of 60 Hz to 5 kHz and has a reduced mounting depth, allowing for easy installation. Additional technical details include Thiele-Small parameters such as Qes 0.73 and Vas 8.5 l, contributing to impressive low-frequency reproduction.

What Thiele-Small parameters does the Prima AP 6.5 Ohm2 have?

The Audison Prima AP 6.5 Ohm2 speaker has important Thiele-Small parameters: Qes 0.73, which describes electrical damping; Qms 4.8, an indicator of mechanical damping; and Qts 0.63, the total quality factor. It also has a Vas of 8.5 l, which describes the equivalent air volume corresponding to the elasticity of the speaker system's suspension. The resonance frequency Fs is 75 Hz, and the moving mass Mms is 10.5 g, which describes the total moving mass including the air mass. These parameters are crucial for optimal low-frequency reproduction and efficiency of the speaker.

How does the 2 Ohm impedance affect the performance of the AP 8.9-Bit Amplifier?

The 2 Ohm impedance of the Audison Prima AP 6.5 Ohm2 speaker is specifically designed to take full advantage of the AP8.9-Bit Amplifier's power. Low impedance means that the amplifier can deliver more current, which is why the 2 Ohm configuration maximizes output power on each channel. This feature allows the amplifier to achieve 65 W per channel at 2 Ohms and provides better control of the speaker at high volumes. The design choice of a 2 Ohm nominal impedance optimizes efficiency and increases the sound pressure level, which is particularly noticeable when listening to music with bass-heavy elements.

What power does the Prima AP 6.5 Ohm2 provide at different frequencies?

The Prima AP 6.5 Ohm2 speaker offers a frequency response of 60 Hz to 5 kHz. At low frequencies, it ensures powerful bass reproduction with its extension down to 50 Hz. The peak power handling is 210 W, which meets complex music demands, while the continuous power is rated at 70 W. The resonance frequency (Fs) is specified at 75 Hz, and the voice coil with a diameter of 25 mm maximizes efficiency at 95 dB SPL. At mid frequencies, the speaker provides a detailed and balanced reproduction, enhanced by the precision of the voice coil and the lightweight construction.

How do I install the Prima AP 6.5 Ohm2 in my vehicle?

The installation of the Prima AP 6.5 Ohm2 speaker from Audison is relatively straightforward thanks to its shallow mounting depth of 58.5 mm and dimensions of 165 mm in diameter. These measurements allow the speaker to be integrated into OEM placements commonly found in vehicle doors. Note the compact size and the protective coating of the basket, which support the placement process. It is advisable to use the high-current quick-start terminal for a robust connection during installation. This allows for quick access and flexible connection, while the plastic cover prevents short circuits.

What aspect of the Prima AP 6.5 Ohm2 contributes to its low distortion?

The Prima AP 6.5 Ohm2 achieves low distortion through an optimized voice coil with a height of 10 mm, allowing for a linear excursion of up to 2.8 mm. The innovative voice coil is equipped with an exclusive "Triple Wave" flat profile TPU surround, which ensures maximum linearity. This structure minimizes distortion even at high sound levels. Additionally, the speaker's paper cone is treated to be water-resistant, and the entire system is optimized using KLIPPEL simulation technology. These advanced manufacturing technologies ensure that distortion-free and clearly defined sound characteristics are guaranteed.

Which car brands is the Prima AP 6.5 Ohm2 compatible with, based on the dimensions?

Although the exact compatibility of the Prima AP 6.5 Ohm2 speaker may vary, its dimensions of 165 mm (diameter) and installation depth of 58.5 mm allow for versatile integration into many common OEM placements. Typical compatibilities can be found in vehicles from leading brands that support such dimensions. The compact basket supports installation in various vehicle models by minimizing space requirements. Before installation, you should check your vehicle's speaker cutouts to ensure this adjustment, and you may need to make minor adjustments for a perfect fit.

What materials are used in the Prima AP 6.5 Ohm2?

The Audison Prima AP 6.5 Ohm2 uses high-quality materials to ensure optimal performance. The voice coil is made from a lightweight material for high efficiency. The paper cone is water-resistant with a special profile developed through FEM simulation technology to maximize sound quality and durability. The surround is made from TPU with an exclusive "Triple Wave" flat profile, ensuring the highest displacement linearity. The basket is robust, abrasion-resistant, and scratch-resistant coated, protecting it from physical influences and thereby extending the speaker's lifespan.

How does the lightweight voice coil affect the speaker's efficiency?

The lightweight voice coil of the Audison Prima AP 6.5 Ohm2 is crucial for its high efficiency of 95 dB. Its reduced mass minimizes inertia, allowing the speaker to respond more quickly to electrical signals. This results in higher sound pressure at the same power consumption, which is particularly advantageous in scenarios with low power reserves, as can occur in many vehicles. Additionally, the lighter voice coil helps reduce distortion, as it reproduces high amplitude signals with less phase lag, which is especially beneficial at high volumes.

What role does the damping epoxy adhesive play in the speaker system?

The damping epoxy adhesive in the Audison Prima AP 6.5 Ohm2 secures the connection of the motor system components and reduces vibrations. This special adhesive minimizes mechanical losses and ensures stable acoustic performance. The firm connection avoids unwanted resonances in the speaker system, contributing to the clarity of the emitted sound. The use of a damping epoxy adhesive is particularly crucial at high sound reproductions, as it ensures the structural integrity of the speaker and extends its lifespan by effectively damping vibrations.
