Dayton Audio GF180-4 Woofer

The Dayton Audio GF180-4 6-1/2" Glass Fiber Cone Woofer delivers powerful, accurate bass and mid-bass response for a wide range of audio projects. Its lightweight yet rigid glass fibre cone ensures clean, low-distortion sound, making it an excellent choice for hi-fi loudspeakers, car audio upgrades, or custom subwoofer enclosures. With a 4-ohm impedance and a total Q factor of 0.42, this woofer is well-suited to both sealed and ported designs, offering flexibility for DIY enthusiasts and professional builders alike.

Technically, the GF180-4 features a copper voice coil wire and a ferrite magnet structure, providing a sensitivity of 90.7 dB at 2.83V/1m for efficient power handling. The 4.4-ohm DC resistance and 1.1 mH voice coil inductance contribute to controlled performance, while the 4 mm maximum linear excursion (Xmax) ensures solid, articulate bass without excessive distortion. The woofer’s 144 mm cut-out diameter and four mounting holes simplify installation, and its 81 mm depth accommodates compact enclosures. With a nominal diameter of 165.1 mm and overall dimensions of 177.8 mm, this driver combines robust build quality with precise engineering for reliable, high-fidelity sound reproduction.
