ADAM Audio Sub10 MK2 10-Inch Active Studio Subwoofer with 200W PWM Amplifier, Down-Firing Bass Reflex Port, and XLR/RCA Connectivity

A sturdy special woofer with extended cone travel and a heavy-duty coil have been optimized for accurate reproduction from a bass reflex enclosure. The down-firing bass reflex tube avoids intrusive ventilation noise because of its generous size and shape. The PWM amplifier produces over 90% efficiency and can handle critical passages without overheating for long periods of time. An additional output allows you to cascade as many subwoofers as needed. The Sub10 MK2 subwoofer provides a precise combination of low cutoff frequency (-3 dB at 25Hz) and an undistorted high sound pressure level (113dB at 1m).
