Designed for small-to-midsized control rooms, the ADAM Audio Sub12 is a powerful subwoofer that extends the low-frequency range of any nearfield or midfield monitoring system down to 22Hz. The Sub12 houses a robust 12" extended-cone-travel woofer with a 2" voice coil driven by a 200W PWM power amplifier which combines low heat generation with high performance to handle maximum power levels during marathon sessions. The rear panel is fitted with two knobs that let you tweak the input level and crossover frequency settings to optimize your monitor setup from your preferred listening position. An additional output lets you cascade as many subwoofers as required for any monitoring setup.
