The Alesis Monitor 1 MKII Passive Monitors (Pair) gived you great accuracy and flat response at an unbeatable price. The 6.5" polypropylene low-frequency driver has a mineral-filled cone and damped linear rubber surround for tighter, more accurate bass response. Features a redesigned pure silk-dome, high-frequency transducer for smooth, accurate high-end detail and response, and a broad sound stage. Magnetically shielded to allow close proximity to video and computer monitors. The cabinet has also been redesigned with SuperPort venting technology to prevent choking and provide low-frequency response well below comparable near-field monitors. The cabinets have a more attractive finish and they're now mirrored for symmetrical speaker placement.
