About the Sophia 3
The Wilson Audio Sophia Series 3 is a three-way, ported floorstanding loudspeaker with a 1-inch inverted titanium-dome tweeter, 7-inch cellulose/paper-pulp composite midrange driver, and 10-inch aluminum-cone woofer. It has a sensitivity of 87 dB, a nominal impedance of 4 ohms, and a minimum impedance of approximately 3.1 ohms at 98 Hz. Wilson Audio specifies a minimum amplifier power of 20 watts per channel. Its reworked crossover and rigid, internally braced cabinet are designed to reduce resonances and time-domain distortion. The stated frequency response is 20 Hz–22.5 kHz, room-average response. Each speaker measures approximately 41.2 inches high without spikes, 13.6 inches wide, and 18.9 inches deep, and weighs approximately 165 pounds. The Sophia Series 3 is no longer in current production.
