Dayton Audio PC105-8 Full-Range Driver

The Dayton Audio PC105-8 4" Full-Range Poly Cone Driver is a versatile and high-performance transducer designed to deliver clear, balanced audio in a compact form factor. Engineered for a wide variety of applications, this broadband driver excels in small-scale sound systems, portable speakers, multimedia enclosures, and custom audio projects where space is at a premium but sound quality cannot be compromised. Its full-range capabilities make it an ideal choice for both DIY enthusiasts and professional installers seeking a reliable, single-driver solution for near-field listening or distributed audio setups.

At the heart of this driver lies a polypropylene composite cone, which provides a smooth frequency response and excellent damping characteristics, reducing unwanted resonances for natural, articulate sound. The total Q (Qts) of 0.64 indicates a well-balanced design suited for sealed or small vented enclosures, while the 86.3 dB sensitivity ensures efficient power handling. With a maximum linear excursion (Xmax) of 2 mm and a robust 6.7-ohm DC resistance, the driver offers controlled bass extension and reliable performance. The 4-ohm voice coil uses CCA wire, and the chassis features a 101.6 mm cutout diameter with four mounting holes for straightforward installation. Whether for upgrading existing systems or building new creations, the PC105-8 delivers dependable, full-range audio with Dayton Audio's hallmark quality.
