WILSON AUDIO ALEXIA

摘要

Wilson Audio claims 90dB sensitivity for the Alexia which accords very well with our measured pink noise figure, averaged for the review pair over the range 400Hz to 20kHz, of 89.8dB. Although this sensitivity isn't particularly high for a system of this size, very low impedance is used to help attain it. Wilson Audio claims a nominal impedance of 4ohm with a minimum of 2ohm at 80Hz but our measurement recorded an even lower minimum of 1.8ohm at 85Hz. Impedance phase angles are quite well controlled but even so the EPDR (equivalent peak dissipation resistance) falls to a scary 0.9ohm at 65Hz.
