Dayton Audio PC68-4 2-1/2 Full-Range Poly Cone Driver – Smooth Output

Overview

The Dayton Audio PC68-4 is a compact 2-1/2 inch full-range driver designed for small enclosures where space is at a premium. It can be used as a stand-alone full-range driver or as a midrange in a 3-way design, and it shines in line arrays, portable speakers, or integrated sound bars. The combination of a small footprint and smooth, balanced response makes it a flexible option for a variety of compact audio projects without demanding oversized cabinets.

Key design elements

• Poly damped woven glass fiber cone controls cone break-up and provides a smooth roll-off
• High energy ferrite magnet increases BL for higher efficiency and increased output
• Rubber surround improves cone linearity and transients
• Smooth response with true full-range reproduction for simple speaker designs

Performance and practicality

Designed to deliver reliable, even response from a small cone diameter, the PC68-4 emphasizes efficiency and consistent behavior across the audible band. The ferrite magnet contributes to higher efficiency and the ability to produce meaningful output without excessive enclosure volume. The rubber surround helps maintain linear motion for clearer transients, which can improve perceived detail in dialogue and musical transients alike.

Ideal setups

• Line arrays for compact, scalable installations
• Portable or ruggedized speaker systems where weight and size matter
• Sound bars needing a dedicated high-fidelity midrange
• One-driver designs or as the midrange in a 3-way configuration

Why choose this driver?

The PC68-4 offers a practical path to smooth, full-range performance in designs that prioritize compact size and straightforward implementation. Its built-in strengths come from the cone material, magnet geometry, and surround damping, all contributing to a balanced and natural listening impression. While performance will depend on enclosure and crossover choices, the driver is positioned to enable clean, confident midrange and extended highs within a compact form factor.

Notes on integration

When integrating into a project, consider enclosure volume, porting (if any), and crossover points that preserve the natural roll-off of the driver. This approach helps you get the most from a small driver without overloading the system.

Practical use and guidance

In real-world builds, the PC68-4 can pair well with compact enclosures to achieve balanced sound across genres, from spoken word to light percussion. Its smooth full-range response may reduce the need for complex crossovers in simple setups, while still offering the flexibility to tailor the sound with careful enclosure tuning.

Durability and reliability

Dayton Audio products are designed for consistent performance. The PC68-4 uses proven materials and construction to support reliable operation across a range of environments, making it a dependable option for hobbyists and professionals alike.
