The Maximo Ultra MKII components are designed for easy installation in the factory locations of most vehicles with excellent off-axis dispersion, high resolution, and crisp detail to overcome some of the acoustic limitations of original speaker placement. The 1-inch (25mm) soft dome tweeter and a 2.5-inch (51mm) midrange are both developed using Morel's EVC technology for high-power handling, and naturally sounding response, and the 5.25″ or 6.5″ woofers utilize large 1-inch diameter voice coils and high-grade ferrite magnet motors capable of excellent bass performance for that instantly recognizable warm Morel sound.
