  • The tweeter – Is a new 25mm (1″) diameter soft dome tweeter, that employs Morel’s external voice coil technology (EVC™) developed specifically for the Maximo Ultra. The tweeter design sets new standards for power handling and low distortion for this price level while delivering an enjoyable musical sound reproduction. Its four mounting options make installation effortless and trouble-free.
  • The midrange – Is a new 2.5″ premium wide-range midrange that employs a powerful double Neodymium magnetic system that features a full Copper sleeve to ensure smooth frequency response and low distortion. It delivers amazing detail and a lush midrange in a compact size.
  • The woofer – Features a high grade Ferrite magnet motor that provides increased magnetic energy with higher power handling and better efficiency than ever before. The new design uses a specially treated paper cone and computer-modeled suspension for a highly linear movement during low midrange frequency reproduction, thus reducing distortion and increasing bass dynamics.
  • The crossover network – Built to handle more power than the speakers using high-grade components. This minimizes component saturation that can make the speakers prematurely distort, allowing the Maximo Ultra to play to its fullest potential.
