How does Direct Servo affect the physical property of drivers so that I can feel it in action? And how does it act differently than accelerometer-based servo subwoofers?
Our Direct Servo technology improves cone control in the form of increased damping. The best way to feel servo in action is to connect the Direct Servo subwoofers in free air and then gently push the cone. One can feel the cone as if it is immersed in a highly viscous oil in both fast push (high frequency) and slow push (low frequency). That is how the driver cone in our Direct Servo subwoofers dissipates unwanted energy from inside the enclosure. On the other hand, accelerometer-based will make it feel like pushing a heavy brick. In other words, its net effect is like adding a heavy mass to the cone. That means more of the internal reflected energy bounces back off the driver cone until other elements in the system such as enclosure walls dissipate that energy. Adding damping is good but adding cone mass should be avoided.
