Alesis has been creating studio monitors for nearly a quarter century. In that time, we’ve learned a thing or two about optimizing sound and sonic clarity. Built using technology adopted from Alesis' Monitor One and M1 Active professional studio monitors, the M1 Active 330 USB Desktop Studio Monitors are the perfect way to upgrade your computer or mobile device experience. Each speaker is housed in a custom-designed anti-resonant wood cabinet that helps provide natural bass. It features an elliptical waveguide with directional articulation technology.
