Dayton Audio CX120-8 4" Coaxial Driver with 3/4" Silk Dome Tweeter

The Dayton Audio CX120-8 is a 4-inch coaxial driver that delivers impressively full-range sound from a remarkably compact footprint. Designed to serve as a complete audio solution in space-constrained applications, this driver combines a capable woofer with a dedicated tweeter to eliminate the need for separate components. It is ideally suited for use in small bookshelf speakers, surround sound channels, portable Bluetooth enclosures, or any custom project where size is at a premium but audio quality cannot be compromised.

At the heart of the CX120-8 lies a polypropylene cone woofer, chosen for its low mass and excellent damping characteristics, which together produce a clean, articulate midrange and controlled bass. The 3/4-inch silk dome tweeter is seamlessly integrated coaxially, ensuring a coherent point-source presentation and delivering crisp, airy high frequencies without harshness. Technical specifications reveal a total Q factor of 0.48, indicating a well-balanced design suitable for both sealed and ported enclosures. With a sensitivity of 88.5 dB and a maximum linear excursion of 3 mm, this driver offers efficient performance and surprising dynamic capability for its size. The 8-ohm impedance and CCA voice coil further contribute to reliable, long-term operation. Whether upgrading an existing design or starting a new build, the CX120-8 provides a versatile, high-quality foundation for compact full-range audio.
