This is an “Old School Classic 6x9 Speaker.”  This full range speaker was wildly popular for automotive installations but works great today in line arrays, organ installations, or PA products. It’s a very efficient full range speaker and it features “whizzer cone” over the voice coil for increasing high frequency dispersion. But don’t under estimate the performance of this speaker. It’s a perfectly suitable speaker for any enclosure. This speaker is front or rear mountable. 

  • Powerful 20 ounce ferrite magnet
  • Engineered paper cone with a high compliance corrugated cloth surround
  • High frequency dual cone for extention and off-axis response.
  • Black powder coated steel basket
  • 70 watts program power

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 are used to validate final design.  Oaktron by MISCO is the premium line of high performance, ready-to-ship transducers for a wide variety of applications including high fidelity, musical instrument, automotive and many more.
