Lowell Model CT830 is a high performance 8-inch coaxial speaker. The 20 watt assembly features a two driver system (woofer and tweeter) with a post mounted, coaxially positioned tweeter for improved performance over a traditional full-range (dual cone) speaker. The 3-inch tweeter provides wide dispersion in the high frequency range; helping to enhance speech and music intelligibility in the region between speaker locations. The high frequency driver is equipped with a first order high pass filter to protect it from harmful bass energy. Frequency response of the assembly is 50Hz-17.5kHz+6dB with a crossover at 4000Hz. The CT830 is an outstanding choice for quality paging, public address and background music applications that demand clear intelligibility with accurate voice and music reproduction. Model CT830 utilizes precision ground, highly efficient ceramic magnets (10oz. LF, 2.1oz. HF) and permanently aligned voice coils (1" LF, .563" HF) to achieve outstanding smoothness and intelligibility. Optional factory-wired transformer for ready-to-install convenience in 70V or 25V distributed system applications.


  • Speaker frame is 20-ga. stamped steel with zinc-plated finish to prevent corrosion and punched holes to mount a transformer.
  • Provides clear, accurate reproduction of music and voice communications.
  • Made in the USA; meets or exceeds all applicable EIA standards
  • Provides optimum low-end performance when teamed with Lowell's acoustic DX-series backbox (1-3 cu.ft.) or protective backbox with acoustic fiberglass batting.
  • Compatible with Lowell 8" grilles.


  • See specification sheet under "Documentation" tab.
