Lowell CT830A
8" 20W Coaxial Speaker


A high performance 8" 20W coaxial speaker, the Lowell CT830A comes with a post-mounted, coaxially-positioned tweeter, improving performance over a traditional full-range (dual cone) speaker. It includes a 3" tweeter that offers broad dispersion in the high-frequency range, enhancing speech/music intelligibility in areas between speakers. It's an outstanding choice for quality public address, paging, and background music applications that demand accurate voice/music reproduction.
