WG165-543A-PR-60-D 6.5-Inch Paper Cone Speaker Driver – 4 Ohm, 60W RMS, Ferrite Magnet

The WG165-543A-PR-60-D is a 6.5-inch speaker driver featuring a paper cone with a “watermelon-rind” designation, a 25mm voice coil, and a ferrite magnetic circuit. With a nominal impedance of 4 ohms, it is rated for 60W RMS power handling and 120W maximum power handling.

Its specified frequency response extends from 50Hz to 4,500Hz, with a sensitivity of 89dB and a resonant frequency (Fs) of 50Hz. These specifications provide reference points for selecting the driver and matching it to the intended speaker system’s operating range.

For custom speaker assembly, DIY audio projects, or compatible replacement applications, this 6.5-inch paper cone driver combines clearly stated electrical ratings with a total weight of 1,779g. The enclosure, mounting arrangement, amplifier, and crossover should be selected to suit the driver’s complete specifications.
