Dayton Audio DMA105-8 4" Aluminum Cone Full-Range Driver

The Dayton Audio DMA105-8 4" Aluminum Cone Full-Range Driver delivers exceptional clarity and detail in a compact form factor, making it an ideal choice for high-fidelity audio projects. This versatile driver excels in applications such as desktop speakers, portable Bluetooth enclosures, and small-scale sound systems where space is limited but audio quality cannot be compromised. Its full-range capabilities allow it to handle both midrange and bass frequencies with precision, eliminating the need for a separate tweeter in many designs.

Technically, the DMA105-8 features an aluminium cone diaphragm that provides excellent rigidity and low mass, ensuring accurate transient response and reduced distortion. The copper voice coil, with a DC resistance of 7.5 ohms, contributes to efficient power handling and thermal stability. With a sensitivity of 84.8 dB at 2.83V/1m, this driver offers reliable output even with modest amplification. The total Q factor (Qts) of 0.63 indicates a well-damped response suitable for sealed or small vented enclosures, while the 2.5 mm Xmax ensures linear excursion for clean bass reproduction. The 4-inch nominal diameter and compact 47.2 mm depth allow for easy integration into tight spaces, with a cutout diameter of 89.9 mm and four mounting holes for secure installation.

Whether you are building a custom sound system or upgrading an existing design, the DMA105-8 provides a balanced, detailed audio experience that belies its small size.
