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.

Lowell CT830A Construction/Features/Specifications:

  • 8" 20W coaxial speaker
  • High frequency driver with first-order high-pass filter to protect it from harmful bass energy
  • Frequency response is 57 Hz - 14 kHz (+6 dB); 44 Hz - 20 kHz (+7.6 dB)
  • Dispersion angle of 80° @ 2000 Hz (-6 dB)
  • Precision-ground, highly efficient ceramic magnets (12 oz. LF, 2.1 oz. HF) and permanently-aligned voice coils (1" LF; 0.563" HF) achieve outstanding smoothness and intelligibility
  • 20-ga. stamped steel frame with zinc-plated finish to prevent corrosion and punched holes (to mount a transformer)
  • Provides optimum low-end performance when teamed with Lowell's acoustic DX-Series backbox (1-3 ft³) or protective backbox with acoustic fiberglass batting
  • Made in the USA with domestic and imported components
  • Meets or exceeds all applicable EIA standards
  • Compatible with Lowell 8" grilles
