Speaker Driver Woofer Glass Fiber 40W 8 Ohm 87dB 50Hz-5000Hz Ø16.5cm
With a flat response down to 4000Hz and excellent low-frequency extension, Dayton Audio's GF180-8 fiberglass diaphragm woofer is ideal for low-cost two-way speakers. The naturally damped, woven fiberglass cone is driven by a four-layer voice coil wound on an aluminum support. This speaker is an excellent choice for a bookshelf speaker, a floorstander or even a portable sound system.
