Here's what Adam say about the sub12:
The Sub12 is a powerful subwoofer designed to extend the low frequency capabilities of any near or midfield monitoring system down to 22 Hz.
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 Sub12 subwoofer provides a precise combination of low cutoff frequency (-3dB at 22Hz) and an undistorted high sound pressure level (115dB SPL at 1m).
