The 93082 is a 6.5” 4 ohm, coaxial speaker mounted with a 1” mylar tweeter set with an 8.4 kHz 1st order crossover. The precision design of this extended range driver allows for optimal sound production in either sealed or vented enclosures, and a Santoprene surround gives longer life to sound systems in hot and cold environments. Ideal for installing in distributed music ceiling systems, or vehicle systems looking for high-power audio and a smooth crossover.

  • Extended voice and music speaker
  • 6.5" (165 mm) steel basket diameter
  • 25 watt, 4 ohm, 90 dB SPL
  • 1" copper voice coil, Kapton former
  • Mylar tweeter, coaxially mounted
  • Polypropylene cone, ferrite magnet

MISCO engineers test and analyze the performance of these speakers using the world's most sophisticated loudspeaker measurement systems including the Klippel Analyzer and the Klippel QC, which confirm the final design.
