The CMS 503DC PI has been fundamentally re-engineered to deliver wider and more consistent broadband directivity, even greater intelligibility, and a more accurate and linear response.The new Dual Concentric driver design features Omnimagnet™ technology and patent-pending Torus Ogive Waveguide™ device, together providing more consistent and controlled directivity along with improved high frequency response. Improved time-alignment and greater coherence between LF and HF results in a wider sweet spot for enhanced performance both onand off-axis. The re-designed baffle provides a subtle extension to the waveguide effect for additional sonic benefits.
