Soft Dome Tweeter
A high-frequency driver design employed by studio monitors (like the PreSonus Eris-series monitors). The round shape of this type of design radiates sound with a wide dispersion pattern to create a larger sweet spot. The larger the diameter of the dome, the wider the sweet spot. Usually made from a high-quality textile, like the silk, these designs are known for their smooth and refined sound. For more information on studio monitors, please see this article.
