When you need a woofer for a professional, high-quality listening experience, choose the 93045. This high sensitivity, “pro-sumer” style woofer uses its low moving mass to create both an excellent transient response and a top-tier level of musical detail. A copper phase plug reduces frequency-phase cancellations and aids internal cooling to reduce power compression. An 8-inch, heavy gauge, stamped steel basket and quick-connect terminals allow for easy, drop-in installation into many enclosures and set-ups.

  • Woofer with copper phase plug
  • 8" (203 mm) basket diameter
  • 75 watts, 8 ohms, 95 dB SPL
  • Light weight, paper cone
  • High compliance, multi-roll surround cloth
  • Quick connect dual terminals for easy connection

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.
