GF180-4 6-1/2" Glass Fiber Cone Woofer 4 Ohm

Quick Overview

Dayton Audio’s GF180-4 6-1/2” glass fiber cone woofer is built to produce powerful bass with smooth midrange response. The woven fiberglass cone and rubber surround damps cone resonances allowing an easy transition to tweeters when crossed over at 2,000 Hz. This affordable woofer is a great choice for 2-way bookshelf speaker designs.

Product Highlights

  • Woven fiberglass cone lowers resonances for smooth response and natural sound
  • 4-layer voice coil on an aluminum former provides excellent heat dissipation
  • Rubber surround helps damp the outside edge of the cone improving high frequency response
  • Vented pole piece releases air trapped under the dustcap for quiet operation
  • Low-profile frame minimizes diffraction making these drivers suitable for surface mount applications
