MediaOne M30BT are compact, active 3-inch studio monitors with Bluetooth. Each channel is driven by a built-in Class AB amp of 10 W (20 W total), delivering full-range sound from 3-inch woven carbon-fiber woofers and 3/4-inch silk-dome tweeters. The black vinyl enclosures feature tuned porting and a Bass Boost switch. Front-panel volume and headphone out, rear RCA inputs, and a 1/8-inch stereo output for subwoofer connection complete the system.
