This 100-Watt 6.5" pro-audio style mid-woofer covers a lot of frequency band - from 40 Hz to over 6,000 Hz. Using an edge wound coil in a strong magnetic field, creates excellent transient response and sensitivity. The cone is light weight engineered paper pulp and is supported by a treated m-roll cloth surround.  The spider is flat - formed to provide optimal suspension linearity.

  • 100 watt maximum power handling,
  • 20 oz ferrite magnet with vented pole for optimal thermal management
  • 1.5" Edge wound voice coil
  • Engineered treated cone and m-roll surround

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. From elegantly simple to highly specialized designs for unique and demanding applications, there is an Oaktron loudspeaker perfectly suited for your needs.
