Don't let the lower prices of this line of subs fool you. While these subwoofers sacrifice some features to offer better affordability, no sacrifices have been made to overall performance and accuracy.
Rythmik subwoofers feature patented Direct Servo technology which provides major advantages to more common accelerometer based servo systems.
Direct Servo uses a very thin sensing coil which is wound adjacent to the voice coil. This coil acts as a custom made microphone which creates a signal that is then fed back to the amplifier to correct differences in real-time. Non linearities are instantly corrected.
