Dual opposed subwoofers mount two drivers on opposite walls of enclosures in an effort to reduce the reaction force exerted onto the enclsoure from drivers . However, the disadvantage of the conventional non-servo dual opposed subwoofers is the boxy bassinside the enclosure is still audible with re-radiation via the cones. With our patented Direct Servo technology, it enables precise control over the cone to resist and dissipate any energy acting on the cone and the so-called re-radiation of boxy bass coloration can be reduced by up to 10x in energy. This is essential for tight, dynamic and accurate bass. It also counteracts many different driver non-linearities and allows us to use lighter drivers which avoid the need for excessive amounts of amplifier power.
