WG165-557A 6.5-Inch Coaxial Speaker – 4 Ohm, 30W RMS, Green Sand-Textured Composite Cone

The WG165-557A is a 6.5-inch coaxial speaker featuring a green sand-textured composite cone, a 25mm voice coil, and a ferrite magnetic circuit. With a nominal impedance of 4 ohms, it is rated for 30W RMS power handling and 60W maximum power handling.

Its specified frequency response extends from 67Hz to 20kHz, with a sensitivity of 91dB and a resonant frequency (Fs) of 67Hz. The coaxial configuration provides a single speaker assembly for compatible audio systems requiring coverage across multiple frequency bands.

The green composite cone and sand-textured finish give the WG165-557A a distinctive appearance for speaker installations with visible drivers. For custom audio builds, DIY speaker projects, or coaxial replacement applications, its stated electrical and acoustic specifications provide reference points for component selection and system matching.
