The Sub10 Mk2 is a powerful active subwoofer that extends the playback range of near- and midfield monitors down to 25 Hz. A robust special woofer with a large excursion and a highly durable voice coil has been optimized for precise reproduction in a bass reflex enclosure. The downward-firing bass reflex port is designed to minimize disruptive wind noise through generous sizing and shaping. The PWM amplifier achieves an efficiency of over 90%, allowing even critical passages to be played for extended periods without overheating. An additional output allows for cascading an unlimited number of subwoofers. For medium to large control rooms, this subwoofer offers an excellent combination of low cutoff frequency (-3 dB at 25 Hz) and high undistorted sound pressure (113 dB SPL at 1 m). All Adam subwoofers feature differentiated options to adapt them to the respective room or satellites. There are controls for volume (-60 to +6 dB), phase switching (180°), and a variable upper cutoff frequency for the subwoofer (50-150 Hz). A filter can be activated for the satellite outputs that blocks signals from the satellites below 85 Hz, allowing for Dolby-compliant film sound reproduction and relieving them from low frequencies. Additionally, the subwoofer can be manually turned on or off, or set to automatically activate when it receives signals (signal-on/continuous).
