Prima AP 6.5 4Ohm

Woofer | 210 W Peak Power | 165 mm | 4 ohm

Audison Prima

Audison Prima was designed to meet the interest of the car model enthusiasts who like to appreciate all the nuances of the musical message with components that are perfectly integrated in the car OEM system, preserving the most precious Prima on Audison requirement of OEM integration: space.

• 75 Hz resonance frequency, to extend the frequency range down to low frequencies up to 50 Hz and increase the SPL in the low range.
• 25 mm mobile voice coil to maximize efficiency achieving 95 dB.
• 10 mm winding height mobile voice coil to increase maximum linear excursion up to 2,8 mm and minimize distortion, even at high listening levels.
• Water-repellent treated paper cone, featuring profile developed with FEM simulation technology and optimized with the Klippel Scan Vibrometer.
• Reduced mounting depth, providing ease of installation in OEM placements.
• TPU (Thermoplastic Polyurethane) surround, featuring the exclusive “Triple Wave” shallow profile, for maximum excursion linearity.
• Compact basket, protected by abrasion-resistant and scratch-proof coating. Damping epoxy glue provides perfect coupling with the motor system.
• High current fast-on terminal with double contact on positive and negative poles for high flexibility and quick connection. The terminal features a temperature resistant plastic cover, protecting it against accidental short circuits.
• Developed with the KLIPPEL suite.

To maximize the woofer efficiency achieving 95 dB, a 25 mm diameter 10 mm winding height coil, so a more lightweight coil, has been employed, at the same time also providing a linear excursion 2.8 mm higher than the one of AP 6.5 (4 ohm), therefore ensuring high SPL values with minimum distortion even at high listening levels. To extend the woofer's frequency range down to low frequencies up to 50 Hz a 75 Hz resonance frequency has been chosen, achieving excellent low frequency output even without the use of a subwoofer.
