The SS-AR2's incorporated drivers support a maximum input power of 100 watts through a 25 mm (one inch) soft dome, a 130 mm (five inch) sliced-paper cone and a 165 mm (six and a half inches) aluminum cone (double-drive system), producing a frequency response from 42 Hz to 60kHz.
The improved bass and low-mid response we noted in our review falls in line with iFixit's confirmation that the new driver in each Pod is made with a paper speaker cone -- in contrast to the plastic used on the older model.
