Eighteen Sound’s XG10 line source waveguide with a 1-inch throat entry was featured at the 2014 Prolight+Sound show in Frankfurt, Germany. The XG10 has a transmission line acoustic design that minimizes internal reflections and acoustic loss, while the throat shape has been optimized for lowering air distortion. When paired with an Eighteen Sound 1-inch exit high frequency compression driver it delivers an unmatched level of performance. The waveguide has been optimized to provide a 10o vertical dispersion angle, while the horizontal coverage angle can vary from 80o to 120o depending upon the specific cabinet design.
