Dayton Audio 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 Product Manuals / Spec Sheets / Downloads Dayton Audio GF180-4 Specification Sheet Dayton Audio GF180-4 Data FilesBuying Options Buy NowBuy Internationally Product Description With flat response to 4,000 Hz and excellent low frequency extension, the GF180-4 6-1/2” glass fiber cone woofer from Dayton Audio is ideal for use in low cost 2-ways speaker designs. The naturally damped woven fiberglass cone is driven by a 4-layer voice coil wound on an aluminum former. This driver is a great choice for you next bookshelf speaker, multiple driver tower, or even portable sound systems.
