Motus Audio drivers
Solen is the authorized dealer for Motus Audio loudspeaker drivers, designed in the US and manufactured in China.
The units used in the speakers seen here (a 6” midwoofer and 1” tweeter) would cost around $570/pair. Interested hobbyists could purchase a kit, including enclosures and crossovers, for under $1000/pair. The system I heard was made of a MacMini, the versatile Resonessence Labs Invicta DAC, and Ayre amplification. Music files were played using the Fidelia playback software. Cables were provided by Cardas. I noted a sweet, smooth sound.
