Stunningly accurate for totally reliable monitoring. The Alesis Monitor One MKII Passive Monitors gived you great accuracy and flat response at an unbeatable price. A few short months after their introduction, the Monitor One Studio Reference Monitors became winners of a TEC Award, the reason being that they provided a wide frequency range, clear imaging, high-power handling and excellent bass transient response, all at an affordable price. The Monitor One Mk2 Studio Reference Monitors build on that tradition while delivering even better performance. New 6.5" polypropylene low-frequency drivers deliver tighter, more accurate bass response. These are matched with newly redesigned 1" pure silk-dome high frequency transducers that deliver a smooth and even response, provide more detail and a broader sound stage. The overall frequency response of the Monitor One Mk2 monitors has been increased at the top end, coupled with more efficient power handling. The cabinets of the Monitor One Mk2 have been redesigned and are now mirror image, left/right pair for symmetrical speaker placement. They also feature radiused edges for reduced edge diffraction, along with improved porting which delivers an improved low-frequency response. Magnetic shielding is provided to allow for their use in close proximity to video and computer monitors.
