Description
The ADAM Audio Sub12 is a powerful 12″ active studio subwoofer designed to extend the low-frequency performance of nearfield and midfield monitoring systems down to 22 Hz, making it ideal for larger control rooms. It features a robust 12″ woofer with extended cone travel, driven by a 300 W RMS high-efficiency PWM amplifier that delivers stable, cool-running performance during long sessions. Down-firing bass reflex tubes minimize ventilation noise while maintaining deep, controlled bass. Rear-panel gain and filter controls allow precise system tuning, while XLR and RCA I/O ensure easy integration into professional setups. With a maximum output of 115 dB SPL, the Sub12 delivers powerful, accurate low-end reproduction and can be cascaded with additional units for expanded coverage.


Deep Bass Output
The Sub12 uses a 12″ long-throw woofer powered by a 300 W RMS high-efficiency PWM amplifier to deliver accurate low frequencies down to 22 Hz with up to 115 dB SPL, making it ideal for larger studio environments.


Flexible Studio Integration
Down-firing bass reflex tubes minimize ventilation noise, while rear-panel gain and filter controls, XLR and RCA I/O, and cascading support allow seamless integration into stereo or surround monitoring systems.
