Dayton Audio PC105-4 Full-Range Driver

The Dayton Audio PC105-4 4" Full-Range Poly Cone Driver is a versatile and high-performance broadband driver designed to deliver clear, natural sound across the entire frequency spectrum. Engineered for compact audio systems, this driver excels in applications where space is limited but sound quality cannot be compromised. It is ideally suited for use in small bookshelf speakers, multimedia monitors, portable Bluetooth enclosures, and custom DIY audio projects. Its full-range capability also makes it an excellent choice for voice coil replacement or upgrading existing multi-way designs where a single driver can handle both midrange and treble duties.

At the heart of the PC105-4 lies a polypropylene composite cone, chosen for its rigidity and low mass, which contributes to a sensitivity of 90.3 dB at 2.83V/1m. The motor system features a 0.32 mH voice coil inductance and a 3.3 ohm DC resistance, ensuring efficient power handling. With a total Q factor (Qts) of 0.51, the driver offers a balanced blend of transient response and low-frequency extension, while the 2 mm linear excursion (Xmax) allows for controlled bass output. The 4-inch nominal diameter fits a 101.6 mm cutout, and the 59.9 mm depth accommodates shallow enclosures. Four mounting holes simplify installation, and the CCA voice coil wire provides reliable conductivity. Priced at 7,390 HUF, this driver delivers exceptional value for compact, full-range audio solutions.
