WG87-2A-PR-15-D 3-Inch Kevlar Cone Speaker Driver – 4 Ohm, 20W RMS, 25mm Voice Coil

The WG87-2A-PR-15-D is a 3-inch speaker driver featuring a Kevlar cone and a 25mm voice coil. With a nominal impedance of 4 ohms, it is rated for 20W RMS power handling and 40W maximum power handling, providing a compact component option for compatible speaker designs.

This Kevlar cone speaker driver has a specified sensitivity of 85dB and a resonant frequency (Fs) of 121Hz. These parameters provide reference points for driver selection, while enclosure design and the intended operating range should be evaluated using the complete driver specifications.

For custom speaker assembly, DIY audio projects, or replacement applications, the WG87-2A-PR-15-D combines a 3-inch nominal size with clearly stated impedance, power, and voice coil specifications. Confirm its electrical compatibility and physical mounting dimensions before integrating it into a speaker system.
