DIY Audio Note AX Two Speaker Demo (Ten Past Midnight) 

High efficiency two way speaker with external crossover. Perfect pairing with low power tube amplifier. DIY Audio Note Meishu Tonmeister 300B is used in this demo. Extremely coherent as if it is a single driver. Mesmerizing. Natural 3D soundstage. Even at low volume, the sound is balanced. In my setup, it's best at 9-10 o'clock. Results have exceeded my expectation.
