2 ohm
AP 6.5 ohm2 woofer has been developed with 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 ohm load. 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.

Features
- 2 impedance, to fully exploit the 65 W power per channel at 2 of the AP8.9 bit amplifier.
- 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.
