FEATURES
The hd 181 speaker is a 2-way passive bass-reflex system featuring an 8″ woofer and a 1″ high-frequency driver, loaded with an 80° x 60° biradial horn. Special loudspeakers and careful tuning have resulted in a speaker with high power handling and durability. The natural and detailed sound is particularly evident with acoustic instruments and vocals, making it pleasant for listeners. All these features make the hd 181 the perfect solution for live music, DJ, touring, as well as for fixed installations. It impresses with its elegant design in a cabinet with rounded corners for heavy-duty use on the road, compact dimensions, high power handling, excellent dynamics, and long throw, as well as excellent speech intelligibility, eliminating typical horn problems.
