Dayton Audio DMA70-4 2-1/2" Aluminum Cone Full-Range Driver

The Dayton Audio DMA70-4 2-1/2" Aluminium Cone Full-Range Driver is a compact yet powerful broadband transducer designed to deliver clear, articulate sound across the frequency spectrum. This driver is ideally suited for portable Bluetooth speakers, desktop monitors, and small-scale audio projects where space is at a premium but sound quality cannot be compromised. Its full-range capability eliminates the need for a separate tweeter in many designs, simplifying crossover networks and reducing overall system complexity.

Engineered with a lightweight aluminium cone, the DMA70-4 offers excellent rigidity and low moving mass, resulting in fast transient response and reduced distortion. The copper voice coil and a total Q factor (Qts) of 0.44 ensure controlled bass response even in small enclosures, while the 86.2 dB sensitivity (2.83V/1m) provides efficient power handling. With a maximum linear excursion (Xmax) of 2 mm and a nominal impedance of 4 ohms, this driver is versatile for both sealed and ported cabinet designs. Its compact 69.9 mm square frame and 63.8 mm cutout diameter make integration straightforward, while the four mounting holes secure installation. Whether for a custom boombox or a high-fidelity mini monitor, the DMA70-4 delivers exceptional performance in a diminutive package.
