Dayton Audio PC68-4 2-1/2" Full-Range Poly Cone Driver

The Dayton Audio PC68-4 is a 2.5-inch full-range poly cone driver that delivers remarkably clear and balanced audio from a compact footprint. Designed as a broadband driver, it excels in applications where space is at a premium but sound quality cannot be compromised. Whether you are building a small bookshelf speaker, a desktop monitor, or a custom sound installation, this driver provides a versatile solution for reproducing the full frequency range with surprising authority.

At the heart of the PC68-4 is a polypropylene cone that offers excellent stiffness and damping, ensuring low distortion and natural vocal reproduction. The driver features a copper-clad aluminium voice coil, which combines lightweight construction with efficient heat dissipation for reliable performance. With a sensitivity of 86.1 dB SPL at 1 metre with 2.83V input, it pairs well with modest amplification. The total Q factor of 0.65 indicates a well-damped response suitable for sealed or small ported enclosures. A maximum linear excursion of 2 mm allows for respectable bass output given its size, while the 4-ohm impedance makes it easy to integrate into multi-driver arrays. The mounting cut-out diameter is 64 mm, with four screw holes on a 73 mm fixing circle, ensuring straightforward installation. For compact, high-fidelity designs, this driver offers an exceptional balance of performance and practicality.
