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
  • Light weight, paper cone
  • High compliance, multi-roll surround cloth
  • Quick connect dual terminals for easy connection
