WG165-558A 6.5-Inch Coaxial Speaker – Blue Magnesium-Aluminum Cone, 4 Ohm, 30W RMS

The WG165-558A is a 6.5-inch coaxial speaker featuring a blue magnesium-aluminum 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 57Hz to 20kHz, with a sensitivity of 88dB and a resonant frequency (Fs) of 57Hz. The coaxial configuration provides a single speaker assembly for compatible audio systems requiring coverage across multiple frequency bands.

The blue magnesium-aluminum cone combines a metal diaphragm construction with a distinctive appearance for installations with visible drivers. For custom speaker assembly, DIY audio projects, or coaxial replacement applications, the WG165-558A offers clearly stated electrical and acoustic specifications to support component selection and system matching.
