DAYTON AUDIO PC105-4 Full Range Speaker Driver 40W 4 Ohm 90.3dB 80Hz-15kHz Ø12.6cm
With the PC105-4, Dayton Audio unveils a full-range speaker driver with a compact form factor and 40Wrms power handling. This speaker delivers smooth, natural sound reproduction. It is ideal for DIY construction or repair of small audio systems, or as a building block for more complex assemblies requiring several drivers of the same type. Despite its small size, the PC105-4 4" delivers good sound reproduction and is suitable for a wide range of uses. It performs well when used as a midrange driver in a three-speaker system. It can also be used in the design/repair of portable speakers, line arrays, soundbars or any other configuration requiring speaker networking.
Here are some of the highlights of the Dayton Audio PC105-4:
- Poly-damped woven fiberglass cone.
- Copper cap maintains inductance and extends frequency response.
- 25.4mm ventilated aluminum voice coil for high power handling.
- High-energy ferrite magnet for high efficiency and performance.
- Harmonious frequency response over a wide soundstage (ideal for single-HP systems).
