Why do non servo subwoofers seem to have a higher crossover frequency than servo subwoofers?
Our Direct Servo subwoofers utilize a frequency region that voice coil inductance has the least effect in impairing the cone control. That is the reason we limit our crossover to frequencies lower than non servo subwoofer. It is possible to achieve a crossover as high as non servo subwoofers, but performance is compromised as the effectiveness of the servo is reduced. In practical use, many subwoofers lack adequate accuracy to be crossed as high as ours. Often one needs to cross low in order to “minimize the damage”, since most subwoofers have inferior sound quality to the bass of the main speakers.
