High Definition DriverThe powerful, high-definition driver used in the ProSub 60 was specifically engineered by Definitive for their task: to deliver rock-solid low distortion bass, reaching down to the lowest subsonic frequencies, with an outstanding quality of superior transient response unequaled in the world. The special ultra-stiff, low-mass cones (for super-fast transient response) are joined to specially formulated surrounds and long-throw voice coils and spiders. The incredibly rigid baskets are engineered to hold the massive magnet structures and large voice coils in absolute alignment. The high temperature voice coils are made of aluminum wound with triple insulated ultra-pure copper wire and baked in epoxy for power handling in excess of 750 watts.
Definitive's Exclusive Infinite Power Source MOSFET Power AmplifiersThe ProSub 60 incorporates Definitive’s digitally-coupled Infinite Power Source amplifier with high-current direct coupled power supply and discrete MOSFET output devices to ensure perfect high-definition resolution and reproduction of the most dynamic program material and demanding sub-bass transients. Construction quality is absolutely state-of-the-art with only the highest quality components used including mil-spec glass epoxy circuit boards and precision resistors and capacitors for many years of faultless superior performance. In addition, tremendous current reserves, high peak-power capabilities and two special sonically invisible protection circuits ensure that this subwoofer can never be overdriven. There is also a convenient, signal-sensing, auto on/off feature.
