Dual Opposed Mounting and Direct Servo Technology

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.

Some of the benefits of Direct Servo include:

• Dramatic reduction of the re-radiation of bass from inside the box, which is commonly referred to as boxy bass.
• The effects of thermal compression are eliminated under normal operation
• Higher efficiency allowing output which would normally require a more powerful amplifier
• Deep bass extension can be achieved using a low mass driver with superior transient response
• Mechanical and thermal memory effects are reduced, further improving transient response
• The (temperature-independent) effective in-box Q value is 0.3 (0.1 for driver itself) resulting in much tighter and accurate bass than conventional designs with typical value of 0.8-0.9 (and even higher when voice coil becomes hot)
