Audison Door speakers Prima AP 6.5 (2 ohm)Front/Rear
Product description

The AP 6.5 Ω2 woofer was developed with a nominal impedance of 2Ω to utilize all the power made available by the AP8.9 bit amplifier, which can deliver 65W to a 2Ω load. To maximize the woofer's efficiency to 95 dB, a coil with a diameter of 25 mm and a winding height of 10 mm was used—a lighter coil, which simultaneously provides a linear excursion that is 2.8 mm higher than that of the AP 6.5 (4Ω), guaranteeing high SPL values with minimal distortion, even at high listening volumes. To extend the woofer's frequency range to low frequencies down to 50 Hz, a 75 Hz resonant frequency was chosen, achieving excellent low-frequency reproduction even without the use of a subwoofer.
