Dayton Audio ND65-8 2-1/2" Aluminum Cone Full-Range Driver

The Dayton Audio ND65-8 is a compact 2-1/2" full-range driver that delivers remarkably clear and detailed sound across the frequency spectrum. Featuring a lightweight aluminium cone and an efficient motor system, this driver is engineered to produce articulate midrange and extended high frequencies, making it an ideal choice for high-fidelity applications where space is at a premium.

This versatile driver excels in a variety of settings, from desktop speakers and portable Bluetooth enclosures to multi-room audio systems and custom sound installations. Its full-range capability eliminates the need for a separate tweeter in many designs, simplifying crossover requirements while maintaining excellent sonic coherence. With a total Q factor (Qts) of 0.41, it is well-suited for both sealed and ported enclosures, offering flexibility in cabinet design.

Technically, the ND65-8 boasts a copper voice coil with an inductance of 1.04 mH and a DC resistance of 7.4 ohms, ensuring stable performance. The aluminium cone provides rigidity and low mass, contributing to a sensitivity of 80.8 dB SPL at 1m/2.83V. A linear excursion (Xmax) of 3.5 mm and a displacement volume (Vd) of 5.4 cm³ allow for surprising bass output from such a small driver. The mechanical (Qms) and electromagnetic (Qes) Q factors are 4.01 and 0.46 respectively, resulting in a well-damped response.

Whether you are designing a compact bookshelf speaker or a bespoke audio project, the Dayton Audio ND65-8 offers exceptional performance and reliability in a small footprint.
