The AP 6.5 Ω2 wooferhas been developed with 2Ω nominal impedance with the purpose of exploiting all the power possible. 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 (4Ω), therefore ensuring high SPL values with minimum distortion even at high listening levels.
