Their last few generations of models have added some things to Wilson’s attractive mix of sonic characteristics: airy, open highs, as well as transparent and silky-smooth mids. The Alexx exhibited all of these desirable qualities, each of them done better, and with greater top-to-bottom coherence, than I’ve heard from any other Wilson speaker here... The very-limited-edition WAMM Master Chronosonic aside, the Alexx is easily the best big speaker Wilson Audio Specialties has produced.
