Perfect Match For the Prima Range of Compact Amplifiers! AP 6.5 2OHM Prima Line - Individual Speaker Components The Audison AP 6.5 2 OHM woofer has been developed with a 2-ohm nominal impedance with the purpose of exploiting all the power made available by the AP8.9 Bit Amplifier capable of 65W into a 2-Ohms load. To maximize the woofer efficiency achieving 95dB, a 25mm diameter 10mm winding height coil, so a more lightweight coil has been employed, at the same time also providing a linear excursion 2.8mm higher than the one of AP 6.5 (4-Ohms), 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 50Hz a 75Hz resonance frequency has been chosen, achieving excellent low-frequency output even without the use of a subwoofer. Features: 2 Ohm impedance, to fully exploit the 65W power per channel at 2-Ohms of the AP8.9 Bit amplifier. 75Hz resonance frequency, to extend the frequency range down to low frequencies up to 50Hz and increase the SPL in the low range. 25mm mobile voice coil to maximize efficiency achieving 95dB. 10mm winding height mobile voice coil to increase maximum linear excursion up to 2.8mm 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.
