Audison Prima AP 6.5 2 ohm 6.5" 17cm Car Midbass Woofer Door Speakers 70w RMS

The Audison Prima AP 6.5 2 ohm is a 6.5" (165 mm) midbass woofer from the Audison Prima range, rated at 70 W RMS and 210 W peak with a 2 ohm impedance — engineered specifically to pair with the Audison AP8.9 bit amplifier.

This listing is the 2 ohm version. The AP 6.5 is also available as a 4 ohm woofer. If you need a full component kit, the Audison Prima APK 165P is a 2-way 6.5" component set from the same Prima range, or the Audison Prima APX 6.5 offers a coaxial option at the same size and power rating.

Audison Prima

Audison Prima is designed for car enthusiasts who want to retain OEM integration while improving sound quality. The focus is on components that fit existing door locations without compromise on space or finish.

The AP 6.5 2 ohm has been developed specifically to exploit the full 65 W per channel at 2 ohm available from the AP8.9 bit amplifier.

• 2 ohm impedance, matched to the 65 W per channel at 2 ohm output of the AP8.9 bit amplifier.
• 75 Hz resonance frequency, extending usable bass output down to 50 Hz without a subwoofer.
• 25 mm voice coil with 10 mm winding height, maximising efficiency at 95 dB and linear excursion up to 2.8 mm.
• Water-repellent treated paper cone, profiled using FEM simulation and validated with the Klippel Scan Vibrometer.
• TPU (Thermoplastic Polyurethane) surround with exclusive "Triple Wave" shallow profile for maximum excursion linearity.
• Reduced mounting depth for straightforward installation in OEM door locations.
• Compact basket with abrasion-resistant, scratch-proof coating and damping epoxy coupling to the motor system.
• High-current fast-on terminals with double contact on positive and negative poles and a temperature-resistant cover to prevent accidental short circuits.
• Developed using the KLIPPEL suite.

The lightweight 25 mm / 10 mm coil achieves 95 dB sensitivity while delivering a linear excursion of 2.8 mm — greater than the 4 ohm AP 6.5 variant — keeping distortion low even at high listening levels.

The 75 Hz resonance frequency extends the woofer's range down to 50 Hz, providing solid low-frequency output in installations where no subwoofer is used.
