A neodymium magnet, a standard for most sound devices works with a 1" Fabric/Polymer composite dynamic balance dome tweeter which serves the purpose of clarifying high frequency response for reproduction of vocals and instruments. A tuned flared port reduces "chuffing" port noise and increases the quality of the sound. Lightweight Bi-laminate composite dynamic balance drivers are used to create damping for high efficiency, bass, and lower distortions. It has a non-resonant all-MDF enclosure and reversible designed cabinents that can be turned upside down to aim up. The Polk Audio CS1 uses magnetic shielding to make sure it is safe to put near other electronic equipment.
